Parts list

1. Drying: Do not use water or other liquids dripping on the inverter
2. Cool: a working environment temperature of the product is 0-40t. preferably a temperature of 10-25`C, at a temperature as low as possible within this range
3. Ventilation: There should be a certain distance between the inverter and other objects, to avoid blocking the product’s vents.
4. Clean: Do install the products in dusty, wood chips or other particles. If the cooling fan is turned on, the particles are involved in the inside of the product, thus affecting the normal work.
5. While inverters and batteries are connected, will produce arcs or sparks, so there should not be around flammable objects such as gasoline, alcohol, etc.

Assemble the inverter

For this big power inverter, because of the heavier weight, preferably mounted on a solid platform, such as the floor, table, or mounting bracket fine. In order to avoid falling off, a platform for supporting the product should bear the weight of sufficient capacity, and it is good with four screws to secure the product.

BATTERY

Voltage and current of the battery

The battery will provide the DC input voltage to the inverter. The voltage rating must comply with the inverter’s input voltage. Excess voltage may cause over-voltage protection and will likely destroy the inverter.

The battery must be capable of supplying enough current for the inverter to operate, and a small battery can not support power for a large load. Under a large load, the battery voltage will drop and may cause the inverter to shut down due to low voltage.

To calculate battery load (current) = Power (W) / Battery rated voltage. Since the inverter uses about 10% additional the actual battery drain is 110% of the load. For example: battery voltage is 12V DC, load is 400W, and the actual current is: 400W+12Vx110%=37A

Battery operating time

Battery operating time depends on battery capacity (AH) and load power (W), the calculation formula as below
Operating Time: battery capacity (AH)/actual current=battery capacity (AH) / (load/battery output voltage x110%)
For example: battery specification: 12V 200Ah, load power is 400W. then the operating time is: 200+ (400+12×110%) “5.4hours

Notice: The nominal battery capacity is the discharge capacity in 20 hours discharge rate. under the condition when the discharge current exceeds this value, the discharge capacity will be reduced. the corresponding discharge time will be shortened than the calculation value. this part of the specification can refer to battery manufacturer, and whether the battery fully charged will also affect the results.

CONNECTION

1. Grounding
   The power inverter has a terminal on the back panel marked ‘Grounding” or . This is used to connect the chassis of the power inverter to the ground.
   The ground terminal has already connected to the ground wire of the AC output receptacle through the internal connecting wire. The ground terminal must be connected to the ground wire, which will vary depending on where the power inverter is installed. In a vehicle. connect the ground terminal to the chassis of the vehicle. On the ship. connect the ground terminal to the ship grounding system: in a fixed position, connect the ground terminal to the earth.
   Warnings:
   • Wake sure the connections are well. The ground wire must be 14AWG 2.08mm’ ) or even larger.
   • Do not operate the power inverter without connecting to the ground. Electric shock hazard may result.

Connect to the battery

1. Please do all the safety precautions before connection. and then check whether the battery voltage is in accordance with the input voltage of the inverter. Only the voltage of the battery according to with the requirements can be allowed to connect with the inverter.
2. The connecting wire must be big enough to bear current, or else the inverter can not support big load because of voltage reduce caused by the small cross-sectional wire. Depending on the below table, please select the input DC wire or larger one.

Notice :

The above table is only for your reference. In practice, the thick wire can be replaced by two thin parallel wires if only the total section acreage of the wire meets the requirements. In high current, the input DC wire may produce voltage drop, therefore, the operating voltage should be subject to the value on the terminals. If the voltage drop is too large, it can increase the acreage of the section or reduce the length of the lead. The recommended length of lead is less than 1m.
Connect the cathode wire of the battery to the cathode terminal (black) on the back panel of the inverter and then connect the anode wire of the battery to the anode terminal (red) on the inverter, and fix them.

Warnings :

1. 1. Please wear an eye patch and work clothes when working around the battery to avoid the acid and corrosive objects harm your eyes and skin.

2. Prepare enough water and soap. In case the acid materials contact eyes or skin, clean it with soap and water as soon as possible. If the acid materials spay to your eyes accidentally, clean it with cold water immediately and then sent it to the hospital.
3. Do not put any combustible material in the location of installation for spark will result when it is connected to the battery.
4. Keep good ventilation. The battery may produce a little inflammable gas when it works, so keep away from the inverter and it is better to install them in different spaces.
5. Fix the connecting wire of the input DC, or it will result in the over-reduction of the voltage or over-temperature of the wire.
6. Reverse connection of the polarities or the short circuit will burn the fuse or result in the permanence damage of the internal elements of the inverter.
7. Take away the metal accouterment, such as ring or watch, when installation to avoid the short circuit.
8. Although there is over-voltage protection, it may also cause damage of the inverter if the input voltage is too high.

How to use solar charging

1. Firstly connect the battery correctly, switch to the correct battery types (Lead Acid or GEL)
2. Connect the solar panel’s positive and negative electrode to the positive and negative terminal of the solar input of the inverter, pay attention to the correct polarity.
3. Normal charging panel quantity of electric charge indicator lights light up, the user can know the size of the battery charging voltage, when the “full” indicator lights up, indicating that the battery is fully charged, the user should promptly disconnect the solar cell and product connected to stop charging, avoid overcharge. Notice: It will destroy the inverter when solar charging input voltage is too high, so please choose a suitable solar panel.

Operational principle:

The inverter converts DC to AC. the conversion process is divided into two steps. the first step is to convert low voltage DC to high voltage DC. and the second step is using the full-bridge converter tech to convert high voltage direct current into alternating current.
The conversion circuit adopts advanced power devices and high-frequency power conversion technology. Compared with the traditional inverter using the power frequency transformer, it has the characteristics of small size, lightweight and high conversion efficiency etc.

Output voltage and waveform:

The output voltage waveform of the inverter is called “quasi sine wave” or “modified sine wave”, it is a step waveform similar to household alternating current, this type of waveform is applicable to most of the load, including linear or switching power supply, transformer, electric motor etc.

Since the output voltage waveform of the inverter is different from AC, RMS with a general analog or digital multimeter can not accurately measure the output of the inverter; please use the true RMS digital multimeter to measure, such as FLUKE 177/179 multimeter.

About soft start technology

1. This inverter has an advanced soft start function. The output voltage rises up from low to normal when the inverter is turned on. Its advantages as below. 1. This can reduce high startup currents, which can make startup easier for large inductive loads.
2. when the cold starts high power load, the inverter may switch off the output because the instantaneous current is too big. At this point, the switch will not turn off the load, and the inverter will automatically switch to soft start mode As for the large inductive loads, such as electric tools and capacitive loads, we suggest turning on the switch of the appliance firstly and then power on the inverter.

Protection Features

1. Input under-voltage alarm: When the input DC voltage is lower than 1V/20.2V, the buzzer will whistle intermittently to remind that the inverter will go into the under-voltage protection. Pay attention to save the data if you are using the computer.
2. Under-voltage protection: The inverter will automatically shut down when the input DC voltage is lower than 9.8V/19.6V. The buzzer will whistle continuously and the green light is off, the red light is on. Please turn off the inverter and use it after recharging the battery.
3. Overvoltage protection: The inverter will automatically shut down when the input DC voltage is higher than 16V/32V.The buzzer will whistle continuously and the green light is off, the red light is on. Please turn off the inverter and adjust the input voltage to the admissible range.
4. Overload protection: The inverter will automatically shut down when the load is higher than the rated power. The buzzer will whistle continuously. Turn off the inverter and resume normal operation after taking away the excessive
5. Short-circuit protection: The AC output will be automatically shut down when short-circuited. It will automatically reset after the problem is solved.
6. Thermal protection: The unit will get hot during operation. If the temperature is higher than 65″C, the inverter will automatically shut down. Then the buzzer will whistle continuously and the green light is off, red light is on. Please turn off the inverter, and continue using it after the temperature goes back to normal naturally. Meanwhile find out the factors causing the fault, such as ventilation, ambient temperature, vent, load power, and so on. It can avoid similar things from happening again.

How To Change Fuse:

1. Firstly disconnect the inverter and external batteries, solar panels, load, etc all the connections.
2. Unscrew the side plate screws and pull out the bottom plate.
3. Use pliers to clamp car fuse inside the product, and pull it out.
4. Replace the same specifications of the car fuse. and then install the bottom and side panels, and screw well.
