Electrical performance

Inverter
Topology

• The inverter/charger is built according to the following topology.
• Inverter: Full Bridge Topology
• AC Charger: Isolate Boost Topology
• Because of high efficiency Mosfets and 16bit, 4.9MHz microprocessor and heavy transformers, it outputs
• The peak efficiency is 88%.

Overload Capacity
The HC series inverters have different overload capacities, making it ideal to handle demanding loads.

• 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.
• For 125%<Load<150%(±10%), beeps 0.5s every 1s and Fault(Turn off) after the 1 minute.
• For 300%≧Load>150%(±10%), beeps 0.5s every 1s and Fault(Turn off) after 20s.

AC charger

• Series 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, charger is able to output max current as long as input AC voltage is in the range of 164-243VAC (95-127VAC for 120V model), and AC freq is in the range of 48-54Hz(58-64Hz for 60Hz model).
• The inverter is with a strong charging current of 120Amp (for 4KW,12V), and the max charge current can be adjusted from 0%-100% via a liner switch at the right of the battery type selector. This will be helpful if you are using our powerful charger on a small capacity battery bank. Fortunately, the liner switch can effectively reduce the max charging current to 20% of its peak.
• Choosing “0” in the battery type selector will disable charging function.

There are mainly 3 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 A/C start until the battery charger reaches 0.3V below the boost voltage, then take this time asT0 and T0×2 = 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 fl oat 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.

  8| De-sulphation| 15.5 (4 Hours then Off)

For 12Vdc Mode Series (2 for 24Vdc Mode ; 4 for 48Vdc Mode)

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), or if the batteries have been left discharged so low that they will not accept a charge. This cycle is a very high voltage charge cycle designed to try to break down the sulphated crust that is preventing the plates taking charge and thus allow the plates to clean up and so accept charge once again.

Charging depleted batteries

• The inverter allows start up and through power with depleted batteries.

• For 12VDC model, after the battery voltage goes below 10V, if the switch is still (and always) kept in “ON” position, the inverter is always connected with the battery, and the battery voltage does not drop below 2V, the inverter will be able to charge the battery once qualified AC inputs are present.

• Before the battery voltage goes below 9VDC, the charging can be activated when the switch is turned to
  “Off”, then to “ON”.

• When the voltage goes below 9VDC, and you accidently turn the switch to OFF or disconnect the inverter from battery, the inverter will not be able to charge the battery once again, because the CPU loses memory during this process.
  Tabel 2.5.3 AC Charging Current for model

• The charging capacity will go to a peak in around 3 seconds. This may cause a generator to drop frequency, making inverter transfer to battery mode.

• It is suggested to gradually put a charging load on the generator by switching the charging switch from min to max.

• Choose the optimal charging current of 0.2C ， The letter C represents the battery capacity

Transfer

• While in the Standby Mode, the AC input is continually monitored. Whenever AC power falls below the VAC Trip voltage (154 VAC, default setting for 230VAC,90VAC for 120VAC), the inverter automatically transfers back to the Invert Mode with minimum interruption to your Hpliances – as long as the inverter is turned on. The transfer from Standby mode to Inverter mode occurs in approximately 8 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 keep your equipment powered up.
• 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 switching when input utility is unstable.

Automatic frequency adjustment

• The inverter is with Auto Frequency adjust function.
• The factory default configuration for 220/230/240VAC inverter is 50Hz, and 60Hz for 100/110/120VAC inverter. While the output freq can be easily changed once a qualified freq is Hplied to the inverter.
• If you want to get 60Hz from a 50Hz inverter, just input 60Hz power, and the inverter will automatically adjust the output freq to 60Hz and vice versa.

Automatic voltage regulation

• The automatic voltage regulation function is for full series of Pure Sine Wave Inverter/ Charger except Instead of simply bypassing the input AC to power the loads, the inverter stabilizes the input AC voltage to a range of 230V/120V±10%.
• Connected with batteries, the inverter will function as a UPS with max transfer time of 10 ms.
• With all the unique features our inverter provides, it will bring you long-term trouble free operation beyond your expectation.

Power saving mode

• There are 3 different working status for this inverter: “Power Saver Auto” 、“Power Saver Off” and “Power Off”.
• When power switch is in “Unit Off” position, the inverter is powered off.
• When power switch is turned to either of “Power Saver Auto” or “Power Saver Off”, the inverter is powered on.
• Power saver function is designed to conserve battery power when AC power is not or rarely required by the loads.
• In this mode, the inverter pulses the AC output looking for an AC load (i.e., electrical Hpliance). 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) detected, the inverter 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 250ms every 30 seconds. This cycle can be customized to 3 seconds turn SW3 on the DIP switch.
• Note : The minimum power of load to take inverter out of sleep mode (Power Saver On) is 25 Watts.
• 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 or “Power Saver On” function should be defeated.

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.

Protect

This series inverter is equipped with extensive protection 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/Overload 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 inverter will go to Over temp protection when heat sink temp. ≥105ºC, and go to Fault (shutdown Output) after 30 seconds. The switch has to be reset to activate the inverter.
• The Inverter has back feeding protection which avoids presenting an AC voltage on the AC input terminal in Invert mode.
• After the reason for fault is cleared, the inverter has to be reset to start working.

WARNING
Never cut the telephone cable when the cable is attached to the inverter and the battery is connected to the inverter. Even if the inverter is turned off. It will damage the remote PCB inside if the cable is short-circuited during cutting.

Fan running
For 1-3KW, there is a temperature-controlled DC fan that starts working according to the following logic. For 4-6 KW, there are two temperature controlled DC fans. The working mode of the DC fan is the same. Therefore, when the inverter is in energy-saving mode, it is controlled by the following logic on the DC terminal side (see Table 2.5.9)

Allow at least 30CM of clearance around the inverter for air flow. Make sure that the air can circulate freely around the unit.
Variable speed fan operation is required in invert and charge mode. This is to be implemented in such a way as to ensure high reliability and safe unit and component operating temperatures in an operating ambient temperature up to 50°C.

• Speed to be controlled in a smooth manner as a function of internal temperature and/or current.
• Fan should not start/stop suddenly.
• Fan should run at minimum speed needed to cool unit.
• Fan noise level target <60db at a distance of 1m.

SW1:Solar/AC Priority :

• Our inverter is designed with AC priority by default. This means, that 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, the inverter will start a battery inverting cycle to protect the battery. After 1 cycle normal charging and AC throughput will be restored.
• The AC Priority and Battery Priority switch is SW1. When you choose battery priority, the inverter will invert from the battery despite the AC input. Only when the battery voltage is reaches a low voltage alarm point(10.5V for 12V), the inverter transfers to AC Input, charge the battery, and switch back to the battery when the battery is charged fully. This function is mainly for wind/solar systems taking utility power as backup.

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 184-253VAC (100-135V for the 120VAC model) is required to protect them. While for some resistive loads that work in a wide voltage range, the input AC range can be customized to 154-264VAC (90-135V for 120VAC model), this helps to power loads with the most AC input power without frequent switches to the battery bank.

SW3:Power Saver Auto Setting :
The inverter is factory defaulted to detect load for 250ms in every 5 seconds. This cycle can be customized to 3 seconds through the SW3 on the DIP switch.

Other features

Battery voltage recovers start After low battery voltage shut off (10V for 12V model/20V for 24V model/40V for 48V model), the inverter can restore operation after the battery voltage recovers to 12Vdc/24Vdc/48Vdc (with power switch still in the “On” position). This function helps to save the users extra labour to reactivate the inverter when the low battery voltage returns to an acceptable range in renewable energy systems. The built-in battery charger will automatically reactivate as soon as the city/generator ac has been stable for 15 seconds.

WARNING

• Never leave the loads unattended, some loads (like a Heater) may cause accidents in such cases.
• It is better to shut everything down after a low voltage trip than to leave your load on, due to the risk of fire.

Conformal Coating

• The entire line of inverters has 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 splashproof.

Please note that if there is a problem obtaining for example 90mm²cable, use 250mm²or 335mm². One cable is always best , but cable is simply copper and all you require is the copper, so it does not matter if it is one cable or 10 cables 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

AC Wiring

We recommend using 10-5Awg wire to connect to the ac terminal block.
There are 3 different ways of connecting to the terminal block depending on the model. All the wirings are CE compliant, Call our tech support if you are not sure about how to wire any part of your inverter.

WARNING

• The output voltage of this unit must never be connected in its input AC terminal, overload or damage may result.
• Always switch on the inverter before plugging in any Hpliance

AC output voltage is low and the inverter turns loads OFF in a short

time.

| Low battery.| Check the condition of the batteries and recharge if possible.
Charger is inoperative and unit

will not accept AC.

| AC voltage has dropped

out-of-tolerance

| Check the AC voltage for proper

voltage and frequency.

Charger is supplying a lower charge rate.| Charger controls are improperly set.| Refer to the section on adjusting the “Charger Rate”.
 | Low AC input voltage.| Source qualified AC power..
 | Loose battery or AC input connections.| Check all DC /AC connections.
Charger turns OFF while charging from a generator.| High AC input voltages from the generator.| Load the generator down with a heavy load.

Turn the generator output voltage

down.

Sensitive loads turn off temporarily when transferring

between grid and inverting.

| Inverter’s Low voltage trip voltage may be too low to sustain certain

loads.

| Choose narrow AC voltage in the DIP switch, or Install a UPS if

possible.

Noise from Transformer/case*| Hplying specific loads such as

hair drier

| Remove the loads

• The reason for the noise from the 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 the transformer.
• According to the characteristics of our inverter, there is one type of load that will most likely to cause rattles of the transformer, that is a half-wave load, load that uses only a half cycle of the power(see figure 1).
• This trends causes an imbalance of the magnetic field of the transformer, reducing its rated working freq from 20KHz to, say, maybe 15KHz (it varies according to different loads). This way, the freq of noise falls exactly into the range (200Hz-20KHz) that the 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.
• Reducing the load power or using an inverter with bigger cHacity will normally solve this problem.
• The noise will not do any harm to the inverter or the loads.
