Electrical Performance

Invert

Topology

The Sigineer Power pure sine wave inverter/charger is built according to the following topology.
Invert : Full Bridge Topology.
Charge : Isolated Boost Topology
When operating in invert mode, the direct current (DC) that enters the inverter from the batteries is filtered by a large input capacitor and switched “On” and “Off” by the Metal Oxide Silicon Field Effect Transistors (MOSFET) at a rate of 50 Hz or 60Hz, and directed into the transformer which steps the voltage up to 230 or 120 volts. The unit has a 16bit, 4.9MHZ microprocessor to control the output voltage and frequency as the DC input voltage and/or output load varies.
Because of high efficiency MOSFETs and the heavy transformers, it outputs PURE SINE WAVE AC with an average THD of 7% (min 3%, max 10% under full linear loads) depending on the load connected and battery voltage.
The peak invert efficiency of Sigineer Power is 90%.

Overload Capacity

The Sigineer Power inverter/charger has different overload capacities, making it ideal to handle demanding loads.
1 For 110%<Load<125%(±10%), no audible alarm in 14 minutes, beeps 0.5s every 1s in the 15th minute, and Fault(Turn off) after the 15th minute.
2 For 125%<Load<150%(±10%), beeps 0.5s every 1s and Fault(Turn off) after the 1 minute.
3 For 300%≧Load>150%(±10%), beeps 0.5s every 1s and Fault(Turn off) after 20s.

Soft Start in Inverter Mode

The inverter is engineered with a “Soft Start” feature.
When the inverter is turned on, the output voltage gradually ramps up from 0VAC to rated voltage in about 1.2 sec. This effectively reduces otherwise very high starting inrush current drawn by AC loads such as Switched Mode Power Supplies and inductive loads. This will result in lower motor inrush current, which means less impact on the loads and inverter.

Caution:

After the inverter is switched on, it takes a finite time for it to self diagnose and get ready to deliver full power. Hence, always switch on the load(s) after a few seconds of switching on the inverter. Avoid switching on the inverter with the load already switched on. This may prematurely trigger the overload protection. When a load is switched on, it may require an initial higher power surge to start. Hence, if multiple loads are being powered, they should be switched on one by one so that the inverter is not overloaded by the higher starting surge if all the loads are switched on at once.

AC Charger

The Sigineer Power pure sine wave inverter/charger is equipped with an active PFC (Power Factor Corrected) multistage battery charger. The PFC feature is used to control the amount of power used to charge the batteries in order to obtain a power factor as close as possible to 1.
Unlike other inverters whose max charging current decreases according to the input AC voltage, Sigineer Power pure sine wave inverter/charger is able to output max charge current as long as input AC voltage is in the range of 164-253VAC for 240Vac models (95-127VAC for 120V models), and AC frequency is in the range of 48 54Hz for 50Hz (58-64Hz for 60Hz).
The Sigineer Power pure sine wave inverter/charger has a very rapid charge current available, and the max charge current can be adjusted from 0%-100% via a liner switch on the DC side of the inverter. This will be helpful if this powerful charger apply charging on a small capacity battery bank.
Choosing “0” in the battery type selector will disable charging function.

There are three main charging stages:
Bulk Charging : This is the initial stage of charging. While Bulk Charging, the charger supplies the battery with controlled constant current. The charger will remain in Bulk charge until the Absorption charge voltage (determined by the Battery Type selection) is achieved.
Software timer will measure the time from charger start until the battery charger reaches 0.3V below the boost voltage, then take this time as T0 and T0×10 = T1.
Absorb Charging : This is the second charging stage and begins after the absorb voltage has been reached. Absorb Charging provides the batteries with a constant voltage and reduces the DC charging current in order to maintain the absorb voltage setting.
In this period, the inverter will start a T1 timer; the charger will keep the boost voltage in Boost CV mode until the T1 timer has run out. Then drop the voltage down to the float voltage. The timer has a minimum time of 1 hour and a maximum time of 12 hours.
Float Charging : The third charging stage occurs at the end of the Absorb Charging time. While Float charging, the charge voltage is reduced to the float charge voltage (determined by the Battery Type selection*). In this stage, the batteries are kept fully charged and ready if needed by the inverter.
If the A/C is reconnected or the battery voltage drops below 12Vdc/24Vdc/48Vdc, the charger will reset the cycle above.
If the charge maintains the float state for 10 days, the charger will deliberately reset the cycle to protect the battery.

De-sulphation

The de-sulphation cycle on switch position 8 is marked in red because this is a very dangerous setting if you do not know what you are doing. Before ever attempting to use this cycle you must clearly understand what it does and when and how you would use it.
What causes sulphation? This can occur with infrequent use of the batteries, nor if the batteries have been left discharged so low that they will not accept a charge. As the saying goes, desperate diseases must have desperate remedies. This cycle is a very high voltage charge cycle especially designed to try to break down the sulphated crust that is preventing the plates from taking a charge and thus allow the plates to clean up and accept a charge once again.

Warning!

The de-sulphation charging should not be carried out on batteries with good conditions.

For Sigineer Power’s model of APC6024D and APC6048D Inverter chargers, the battery type selector position of “9” is customized with special charging algorithm for lithium battery modules from Tesla ModelS.
The algorithm has only Bulk Charging (Constant Current) to charge the battery, when the battery is charged to high voltage alarm, the charger will shut off and inverter goes to battery mode.

Warning : The output of these units will be de-rated by about 10% when the battery voltage drops below the nominal cut off of 20V and 40V.
For other models, the battery type selector position of “9” is customized with special charging algorithm for Sigineer Power lithium battery packs.

Note : The battery type selector of “0” will disable the charger when the battery voltage is over 11.25Vdc for 12V models, 22.5V for 24V models, 45V for 48V models.

Charging depleted batteries

Unlike some other competing inverters that need a qualified DC voltage to activate its charger, the Sigineer Power pure sine wave inverter/charger allows start up and power bypass with depleted batteries. As long as qualified AC power inputs, these inverters will charge batteries even when the battery voltage is 0 volt. This is a great feature to wake up lithium batteries.

Charging current for each model

The charging capacity will go to peak in around 3 seconds, this may probably cause a generator to drop frequency, making inverter transfer to battery mode.
It is suggested to gradually put charging load on the generator by switching the charging switch from min to max, together with the 15s switch delay, our inverter gives the generator enough time to spin up.

Changing max charging current

The battery type selector position of “0” will disable battery charger when battery voltage is over 11.25Vdc for 12Vdc models, 22.5V for 24V models, 45V for 48V model.
If the battery voltage is below this level, the inverter will force the charging when AC input is qualified.

The “Charge Current Control” knob will enable the user to control the max charging current from 15% to maximum.

Caution Please use a small jeweler’s style flat-head screwdriver to turn the charge current control switch gently to avoid breakage due to over- turning.
To guarantee the best performance of AC charger when the AC input is from a generator, the standby generator should be of at least 150% higher capacity than the inverter.
Warning! Operation with an under-rated generator or generator with unqualified wave form may cause premature failure which is not under warranty.

Transfer

While in the Standby Mode, the AC input of the inverter is continually monitored. Whenever AC power falls out of the trip voltages, the inverter automatically transfers back to the Invert Mode with minimum interruption to your appliances.
The transfer from Standby mode to Inverter mode occurs in approximately 6 milliseconds, with the worst case of 10 milliseconds. And it is the same time from Inverter mode to Standby mode.
Though it is not designed as a computer UPS system, this transfer time is usually fast enough to hold them up as devices like computers can generally tolerate a max power loss of 20ms.
There is a 15-second delay from the time the inverter senses that continuously qualified AC is present at the input terminals to when the transfer is made. This delay is built in to provide time for a generator to spin-up to a stable voltage and avoid relay chattering. The inverter will not transfer to generator until it has locked onto the generator’s output. This delay is also designed to avoid frequent switch when input utility is unstable.

Power Saver

There are two different working statuses for SIGINEER POWER inverter: “Power On” and “Power Off”.
When power switch is in “Unit Off” position, the inverter is powered off.
When power switch is turned to either “Power Saver Auto” or “Power Saver Off”, the inverter is powered on.
Power saver function is dedicated to conserve battery power when AC power is not or little required by the loads.
In this mode, the inverter pulses the AC output looking for an AC load (i.e., electrical appliance). Whenever an AC load (greater than 25 watts) is turned on, the inverter recognizes the need for power and automatically starts inverting and output goes to full voltage. When there is no load (or less than 25 watts) being detected, the inverter will automatically goes back into search mode to minimize energy consumption from the battery bank.
In “Power saver on” mode, the inverter will draw power mainly in sensing moments, thus the idle consumption is significantly reduced.
The inverter is factory defaulted to detect load for 250 ms in every 3 seconds. This power sensing can be customized to “Unit off charging” via the SW3 on DIP switch.

• Power saver on

• Power saver off

• Power saver on (Load detected)

Note : The minimum power of a load to take inverter out of sleep mode (Power Saver On) is 50 Watts. For split phase models, the power threshold of sleep mode is 50W between Hot1 and Neutral and 200W between Hot 1 and Hot 2. There is no load detection between Hot2 and Neutral.
The whole Sigineer Power inverter line is designed with extraordinarily low idle power consumption which is approximately 2.5% of its rated power.

Sigineer Power Inverter/Charger Idle Power Consumption(in Watts)

For more detailed technical information, please contact us at [email protected].

When in the search sense mode, the green power LED will blink and the inverter will make a ticking sound.
At full output voltage, the green power LED will light steadily and the inverter will make a steady humming sound. When the inverter is used as an “uninterruptible” power supply, the search sense mode function should be deactivated.

Exceptions

Some devices when scanned by the load sensor cannot be detected. Small fluorescent lights are the most common example. (Try altering the plug polarity by turning the plug over.) Some computers and sophisticated electronics have power supplies that do not present a load until line voltage is available. When this occurs, each unit waits for the other to begin. To drive these loads either a small companion load must be used to bring the inverter out of its search mode, or the inverter may be programmed to remain at full output voltage.
Note : For split phase models, the power saver functionality is only available on Hot 1.

Protections

The Sigineer Power inverter/charger is equipped with extensive protections against various harsh situations/faults.
These protections include:
AC Input over voltage protection/AC Input low voltage protection
Low battery alarm/High battery alarm
Over temperature protection/Over load protection
Short Circuit protection (1s after fault)
Back feeding protection

When Over temperature /Over load occur, after the fault is cleared, the master switch has to be reset to restart the inverter.
The Low battery voltage trip point can be customized from defaulted value of 10 VDC to 10.5VDC through the SW1 on the DIP switch.
The inverter will go to over temperature protection when the heat sink temperature is ≥105ºC(221℉), and will go to Fault (shutdown Output) after 30 seconds. After temperatures drops to 90ºC(194℉), the switch has to be reset to activate the inverter.
The Sigineer Power Inverter is with back feeding protection which avoids presenting an AC voltage on the AC input terminal in Invert mode.
After the cause for fault is cleared, the inverter has to be reset to resume working.

LED Indicator

Please refer to ‘Indicator and Buzzer’ for the detailed information.

LCD Remote Control

Apart from the switch panel on the front of the inverter, an extra LCD remote control panel connected to the RJ45 port at the DC side of the inverter through a standard CAT-7 cable can also control the operation of the inverter remotely.
If an extra LCD remote control panel is connected to the inverter via “remote control port”, together with the power switch panel on the inverter case, the two panels will be connected and operated in parallel.

Whichever first switches from “Unit Off” to “Power saver off” or “Power saver on”, it will power the inverter on.
If the commands from the two panels conflict, the inverter will accept command according to the following priority:
Power saver on> Power saver off> Power off
Only when both panels are turned to “Unit Off” position, will the inverter be powered off.
The suggested length between the switch panel and inverter is 10 meters.
Never cut the remote cable when the cable is attached to inverter and battery is connected to the inverter.
Even the inverter is turned off, this will damage the remote PCB inside if the cable is short circuited during cutting.

LCD remote control panel(optional)

Note:

When the inverter is in Battery Priority mode, “AC: abnormal” will also be displayed when the inverter finishes a complete charging circle and switches to inverter mode.
“AC: abnormal” only means the inverter doesn’t accept AC input or there is no AC input, it doesn’t mean the inverter is abnormal.
In AC mode, the LCD will not display the status of AC load.

Audible Alarm

The inverter also gives audible alarms when the following situations occur.

Battery Voltage Low| Inverter green LED Lighting, and the buzzer beep 0.5s every 5s.
---|---
Battery Voltage High| Inverter green LED Lighting, and the buzzer beep 0.5s every 1s, and Fault after 60s.
Invert Mode OverLoad|

1. 110%<load<125%(±10%), No audible alarm in 14 minutes, Beeps 0.5s every 1s in 15th minute and Fault after 15 minutes;
2. 125% <load<150%(±10%), Beeps 0.5s every 1s and Fault after 60s;
3. Load>150%(±10%), Beeps 0.5s every 1s and Fault after 20s;

Over Temperature| Heat sink temp. ≥105ºC(221℉), Over temp red LED Lighting, beeps 0.5s every 1s;

FAN Operation

For Sigineer Power 1500W-6000W models, there is one multiple controlled DC fan.
The DC fan is designed to operate according to the following logic:

Allow at least 30 CM of clearance around the inverter for air flow. Make sure that the air can circulate freely around the unit.
Fan noise level <60db at a distance of 1m.
The transformer is rated at 180 degrees Celsius, special attention should be paid to the hot inverter box around it. Don’t touch it.

DIP Switches

On the DC end of inverter, there are five DIP switches which enable users to customize the performance of the device.

SW1:Low Battery Trip Point

Deep discharge of the lead acid battery leads to high losses in capacity and early aging. In different applications a different low voltage disconnection level is preferred. For example, for solar applications, user may intend to have less DOD to prolong the battery life cycle. While for mobile applications users may intend to have more DOD to reduce battery capacity and on board weight.
For 12VDC models, the inverter Low Battery Trip Point is selectable at 10.0/10.5VDC.
For 24VDC models, the inverter Low Battery Trip Point is selectable at 20/21VDC.
For 48VDC models, the inverter Low Battery Trip Point is selectable at 40/42VDC.

SW2:AC Input Range

There are different acceptable AC input ranges for different kinds of loads.
For some relatively sensitive electronic devices, a narrow input range of 176-242VAC for 120/240 Vac split phase models (100-135V for 120Vac models) is required to protect them.

While for some resistive loads which work in a wide voltage range, the input AC range can be customized to 160-264VAC for 120/240Vac split phase models (90-135V for 120Vac models), this helps to power loads with the most AC input power without frequent switches to the battery bank.
In order to make the inverter accept dirty power from a generator, when the SW2 is switched to position “1”, the inverter will bypass an AC input with a wider voltage and frequency (40Hz plus for 50Hz/60Hz).
Accordingly, the AC charger will also work in a wider voltage and frequency range (43Hz plus for 50Hz/60Hz).
This will avoid frequent switches between battery and generator. But some sensitive loads will suffer from the low quality power.
The pros and cons should be clearly realized.

SW3: Power Save Override ON/OFF

Under the Battery Priority Mode (SW5 in position “1”), the inverter can be switched between two modes:
Power Saver Mode (SW3 in position “1”) and Unit Off Charging Mode (SW3 in position “0”). The power Switch should be in “Power saver on” position all the time for using these functions.
In Power Saver Mode, the inverter is initially in standby mode and sends a pulse to detect the presence of a load every 3 seconds. Each pulse lasts for 250ms. The inverter will remain in standby mode until a load has been detected. Then it will wake up from standby mode and start to invert electricity from the battery bank to supply the load. As this function is under Battery Priority, the inverter will always prefer to invert electricity from battery first even there is a qualified AC input present. Only when the battery voltage is lower than the low voltage alarm point, will the inverter switch to AC input power to charge the battery and supply the load at the same time.
This Power Saver Mode can be changed to Unit Off Charging mode via SW3 by switching it to “0” position (SW5 still in “1”).
“Unit Off Charging” will enable the inverter charger to charge batteries as much as possible while without discharging them.
In “Unit Off Charging” mode, the inverter will stay in standby mode without sensing loads. It won’t output any power even if a load is turned on, and only stay idle in this mode when there is no AC input.
When a qualified AC input is present, it will start charging the battery and transfer power to loads.
This feature is ideally suitable for applications where energy conservation for batteries is required.
Charging will be activated once qualified AC exists, while discharging is disabled.
The inverter only consumes as little as 3 watts in “Unit Off Charging” mode.

SW4: Output Frequency

The output frequency of the inverter can be set at either 50Hz or 60Hz by SW4 which make the inverter charger an international models for most electricity systems.

SW5: AC/Battery Priority

The Sigineer Power inverter chargers are designed with AC/Battery priority switch (DIP switch #5).
Switch the battery priority selector to Position “0” for AC priority mode, Position”1” for battery priority mode. In AC priority mode, when AC input is present, the battery will be charged first, and the inverter will transfer the input AC to power the load. Only when the AC input is stable for a continuous period of 15 days will the inverter start a battery inverting cycle to protect the battery. After one normal charging cycle is completed, ac power bypass will be restored.
When you choose battery priority, the inverter will invert from battery despite the AC input.
When the battery voltage reaches the low voltage alarm point higher than “Low Battery Trip Point” (the gap between low battery alarm and cut off is 0.5Vdc for 12Vdc, 1Vdc for 24Vdc, 2V for 48Vdc), the inverter will transfer to AC input, charge battery, and switch back to battery when the battery is fully charged. This function is mainly for wind/solar systems using utility power or generator as back up.

The AC/Battery Priority function can be activated by sliding the switch even when the inverter is in operation

Note: In battery priority mode, when qualified AC inputs for the first time and the battery voltage is below 12.5Vdc (12.5Vdc for 12Vdc, 25Vdc for 24Vdc, 51Vdc for 48Vdc), the inverter will first carry out a cycle of bulk charging and absorb charging, the inverter will not go into float charging mode. Choosing the battery type selector to “0” will disable the built-in battery charger while still allow transfer through. When battery charger is disabled, if the battery is charged by external DC power to 13.5Vdc (13.5Vdc for 12Vdc, 27Vdc for 24Vdc, 54Vdc for 48Vdc), the inverter will go to battery priority mode again.

Auto Generator Start

The inverter can start up generator when battery voltage goes low.
When the inverter goes to low battery alarm, it will send a signal to start a generator and turn the generator off after battery charging is finished.
The auto gen start feature will only work with generators which have automatic starting capability. The generator must have start and stop controls [i.e., an electric starter and electric choke (for gasoline units)], and the safety sensors to be able to start and stop automatically.
There is an open/close relay (constant open) that will close and short circuit the positive and negative cables from a generator start control. The input DC voltage can vary, but the max current the relay can carry is 16Amp.
The Auto Generator Start terminal pins are not polarized.
In addition, these two pins can also be used as dry contacts to send out “Low Battery Voltage” signal to an external alarm device.
This AGS relay can also carry AC voltage within its capacity.
This inverter will skip the float charging when it is set at battery priority mode, so that the generator will no longer be kept running to maintain a small charge on the batteries.

Battery Temperature Sensing

Applying the proper charge voltage is critical for achieving optimum battery performance and longevity. The ideal charge voltage required by batteries changes with battery temperature.
The battery temperature sensor allows the charge controller to continuously adjust charge voltage based on actual battery temperature.
Temperature compensation of charge voltage assures that the battery receives the proper charge voltage as battery temperature varies.
The entire line are compatible with Battery Temperature Sensing for increased charging precision.
It sends precise information to the charger, which automatically adjusts voltage to help ensure full battery charge depending on the ambient temperature of your battery installation.
When the battery temperature is over 40℃(104℉), it will reduce the charging voltage by 0.1Vdc with every degree of temperature rise.
We recommend that you install Battery Temperature Sensors on all banks to protect your batteries and to provide optimal charging of each bank.
The battery temperature sensor mounts on the side of a battery or any other location where the precise temperature of battery can be detected such as battery mounting racks.
The following table describes approximately how much the voltage may vary depending on the temperature of the batteries.

down point by 0.5Vdc
BTS ≥ 50℃(122℉)| Over Temp Fault
A Battery Temperature Sensor has been provided as an optional accessory, it should be bought separately. It comes with 32.8’/10m cable.|
---|---

Important : If the battery temperature is allowed to fall to extremely cold temperatures, the inverter with a BTS may not be able to properly recharge cold batteries due to maximum voltage limits of the inverter.
Ensure the batteries are protected from extreme temperatures.

GFCI Outlet

For Sigineer Power 1500W to 6000W 120Vac single phase and 120/240Vac split phase models, there is a GFCI (ground-fault circuit interrupter) outlet in the vicinity of the AC terminal block.

The GFCI is an electrical safety device that quickly breaks an electrical circuit with leakage current to ground. It is to protect equipment and to reduce the risk of serious harm from an ongoing electric shock.
This GFCI is wired in parallel with the AC terminal block and they can output a maximum of nominal power.
For the 120/240Vac split phase models, the GFCI is installed on the Hot 1 line.
The GFCI amperage rating is 20A for all models.
The GFCI has no overload protection.

Automatic Neutral-to-Ground Bonding

The automatic neutral-to-ground bonding feature uses an internal relay that automatically connects the AC neutral output to the vehicle/boat’s safety ground (“bonding” it) in Inverter Mode and disconnects it (“un-bonding” it) when they have connected to a qualified external AC source.
The inverters with model # of APC3012NC/APC3024NC/APC3048NC are equipped with automatic neutral-to-ground switching.

This design avoids two neutral-to-ground connections from existing at the same time, thereby preventing an electrical shock hazard between the vehicle/boat’s neutral and the external AC source’s neutral.

Disabling the Automatic Neutral-to-Ground Connection

In some installations, this feature must be disabled.

To accommodate these situations, the automatic Neutral-to-Ground Connection system can be deactivated, so it will not bond the neutral in any mode of operation.
If you are not sure whether you must disable this feature, please refer to your local code requirements or contact us at [email protected] for details.
There is a section of green wire with the insulated connector at the left side of the AC terminal block. This insulated connector connects the neutral and ground inside the inverter while inverting.
Pull the two ends of the insulated connector apart to separate the green wire; this will prevent the neutral and ground from connecting inside this inverter.
If possible, use electrical tape to insulate the disconnected ends, move the two ends away from each other and push back out of the way. Typically when connecting to a house panel (after disconnecting city power from it) , you would disconnect this connection as a house panel already has the neutral to ground bond.
Typically in a standalone system or in a vehicle, you would want to keep this connection.

• Automatic Neutral-Ground Bonding Activated
  

• Automatic Neutral-Ground Bonding Deactivated
  

NOTE : The PSW71512NC and PSW1524NC inverter chargers are built with automatic neutral to ground bonding without cable connectors on the AC terminal block, this feature can’t be deactivated.

Lithium Battery Wakeup

Lithium-ion battery will enter sleep mode when it is over discharged. When the protection circuit is triggered, the voltage could drop to 0Vdc.
Such batteries are assumed useless to most competing inverter chargers which require a minimal DC voltage to power on.
This makes it possible for a charger to charge ordinarily.

The whole line of Sigineer Power inverters will use AC input power to wake up over discharged lithium battery by a boost circuitry.
When they detect a 0V battery, the charger will output a small current to awaken the lithium batteries.

Once the lithium battery voltage is charged back to normal or over normal voltage, the charger will proceed with the preset charging settings.

Other Features

Low Battery Voltage Recovery Start

After low battery voltage shut off (10V for 12V model or 20V for 24V model or 40V for 48V model), the inverter is able to restore to work after the battery voltage recovers to 13.5V/27V/54V(with power switch still in “On” position). This function helps to save the users extra labor to reactivate the inverter when the low battery voltage returns to acceptable range in renewable energy systems.
For the models with Tesla model S module algorithms in position 9, the recover voltage is 23.5V for 24V, 47V for 48V models.

WARNING

Never leave the loads unattended, some loads (like a Heater) may cause accidents in such cases. It is better to shut everything off after low voltage trip than to leave your load in the risk of fire. Nobody wants to return home, finding house surrounded by fire trucks and naughty neighborhood kids toasting hot dogs against his house.

Conformal Coating

The entire line of inverters have been processed with a conformal coating on the PCB, making it water, rust, and dust resistant.
While these units are designed to withstand corrosion from the salty air, they are not splash proof.

Warning! Operation in a condensing environment will invalid warranty.

DC Wiring Recommendation

The battery terminal bolt size is M8.
It is suggested the battery bank be kept as close as possible to the inverter. The following table is a suggested wiring option for DC cable with length from 1 meter to 5 meters.

Model Watt| Battery Voltage| Minimum Wire Gage| Model Watt| Battery Voltage| Minimum Wire Gage
---|---|---|---|---|---
0~1.0m| 1.0~5.0m| 0~1.0m| 1.0~5.0m
1.5KW| 12 Vdc| 30mm²| 40mm²| 4KW| 12 Vdc| 120mm²| 150mm²
1.5KW| 24 Vdc| 15mm²| 20mm²| 4KW| 24 Vdc| 60mm²| 75mm²
3KW| 12 Vdc| 90mm²| 120mm²| 4KW| 48 Vdc| 30mm²| 45mm²
3KW| 24 Vdc| 45mm²| 60mm²| 5KW| 24 Vdc| 75mm²| 95mm²
3KW| 48 Vdc| 25mm²| 30mm²| 5KW| 48 Vdc| 40mm²| 50mm²
6KW| 24 Vdc| 90mm²| 120mm²| 6KW| 48 Vdc| 45mm²| 60mm²

Please follow the above minimum wire size requirement.

One cable is always best, but if there is a problem obtaining for example 100mm²cable, use 250mm²or 335mm²instead, as long as the square area adds up. Performance of any product can be improved by thicker cable and shorter runs, so if in doubt round up and keep the length as short as possible.
Battery cables must have crimped (or preferably, soldered and crimped) copper compression lugs unless aluminum mechanical lugs are used. Soldered connections alone are not acceptable. High quality, UL-listed battery cables are available .These cables are color-coded with pressure crimped, sealed ring terminals.
Battery terminal must be clean to reduce the resistance between the DC terminal and cable connection. A buildup of dirt or oxidation may eventually lead to the cable terminal overheating during periods of high current draw. Use a stiff wire brush and remove all dirt and corrosion from the battery terminals and cables.

Reducing RF interference

To reduce the effect of radiated interference, twist the DC cables. To further reduce RF interference, shield the cables with sheathing /copper foil / braiding.
Taping battery cables together to reduce inductance
Do not keep the battery cables far apart. In case it is not convenient to twist the cables, keep them taped together to reduce their inductance. Reduced inductance of the battery cables helps to reduce induced voltages. This reduces ripple in the battery cables and improves performance and efficiency.

WARNING

| The torque rating range for DC terminal is 12.5NM-20.5NM(9.25-15.19 pound- foot), and  the suggested torque rating is 17NM(12.6 pound-foot). Over torquing may cause the bolt to break.
---|---
Equipment Damage
The inverter is not reverse polarity protected. Reversing the battery polarity on the DC input connections will cause permanent damage to the inverter which is not covered under warranty. Always check polarity before making connections to the inverter.
The inverter contains capacitors that may produce a spark when first connected to battery.
Do not mount in a confined a battery or gas compartment.
Ensure the inverter is off before disconnecting the battery cables, and that AC power is disconnected from the inverter input.

AC Wiring Recommendation

We recommend using 10 to 5Awg wire to connect to the AC terminal block.
When in AC mode the AC input power will support both the loads and AC charger, a thicker wire gauge for AC Input is required. Please consult a qualified electrician about the specific wire gauge required in terms of wire material and inverter power.
There are 3 different ways of connecting to the terminal block depending on the model. Contact our tech support if you are not sure about how to wire any part of your inverter. Send email to [email protected].

Caution:
Wiring Option 2 and Wiring Option 3 are only allowed for split phase models.
Please wire all the other models according to Wiring Option 1.

WARNING

| For split phase models, AC input neutral is not required in wiring. Never Connect Input Neutral to Ground or to Output Neutral. Otherwise damage will occur which is not covered under warranty.
The output voltage of this unit must never be connected in its input AC terminal, otherwise, overload or damage may occur.
Always switch on the inverter before plugging in any appliance.
Damages caused by AC wiring mistakes are not covered under warranty.
---|---

Note:

As the two split phase hot lines are 180 degrees out of phase with each other, the inverter is only able to output full power at 240Vac.
Users can only get 50% nominal power from each one of the 120Vac hot lines of the split phase inverter.
The biggest 120V single load the inverter can drive is 50% of its nominal power.
Preventing Paralleling of the AC Output
The AC output of the unit should never be connected to the utility power / generator.
Such a connection may result in parallel operation of the different power sources and AC power from the utility / generator will be fed back into the unit which will instantly damage the inverter and may also pose a fire and safety hazard.

Grounding

Connect an AWG 8 gauge or greater copper wire between the grounding terminal on the inverter and the earth grounding system or the vehicle chassis

Noise from Transformer/case*| Applying specific loads such as hair drier| Remove the loads

*The reason for the noise from transformer and/or case
When in inverter mode and the transformer and/or case of the inverter sometimes may vibrate and make noise.
The noise may come from transformer.
According to the characteristics of our inverter, there is one type of load which will most likely to cause rattles of transformer, that is a half-wave load, load that uses only a half cycle of the power(see figure 1).
This trends to cause imbalance of magnetic field of transformer, reducing its rated working frequency from 20KHz to, say, maybe 15KHz (it varies according to different loads). This way, the frequency of noise falls exactly into the range (200Hz-20KHz) that human ear can sense.

The most common load of such kind is hair drier.
If the noise comes from case.
Normally when loaded with inductive loads, the magnetic field generated by transformer keeps attracting or releasing the steel case at a specific freq, this may also cause noise.
This noise may also be generated the moment a load is detected in the power saver mode.
Reducing the load power or using an inverter with bigger capacity will normally solve this problem.
The noise won’t do any harm to the inverter or the loads.
