ASSEMBLE

1. The position of mounting First ensure that there is enough space to install the inverter, while the installation location must meet the following requirements:

2. Drying: Do not use water or other liquids dripping on the inverter.

3. Cool: a working environment temperature of the product is 32 ~104 °F, preferably a temperature of 50~77°F, at a temperature as low as possible within this range.

4. Ventilation: There should be a certain distance between inverter and other objects, to avoid blocking the products vents.

5. Clean: Do not install the products in the dusty, wood chips or other particles. If cooling fan is on, the particles involved in the inside of the product, thus affecting the normal work.

6. Inverters and batteries when connected, will produce arcs or sparks, so there should not be around flammable objects such as gasoline, alcohol, etc.

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

8. Assemble the remote controller box

9. Fix the remote box on flat surface where a hole should be made, and use 2 screws to fix it through the two mounting holes on the remote controller.

10. Hang the remote on the fixing screws.

11. Connect the remote box and inverter with the wire.

Note: In case not connect to the remote controller, the inverter can be also used as a normal pure sine wave inverter, turned on by the power switch on the item.

BATTERY

1. Current and voltage
   The battery is designed to supply the unit with DC input voltage and the rated voltage should be in accordance with the rated input voltage of the inverter. Any voltage exceeds the range of the input voltage of the inverter will cause over voltage or under voltage protection.
   In the meantime, the battery should supply sufficient current. The small capacity battery cannot drive the large power electrical appliance. In this case, the battery will be in under voltage protection because of the over- discharge of the battery.
   The simple calculation method of battery current is: load power divided by battery voltage. Due to the consumption of the inverter itself, the actual current will be about 10% larger. For example, the voltage of battery is 12VDC, and load power is 1000W, therefore, the actual current of the battery is about 1000W÷12V×110%≈91.6A.

2. Battery operating time
   Battery operating time depends on battery capacity and current, and the calculation formula of operating time is: battery capacity÷current=battery capacity÷(the load power÷battery voltage×110%). For example, battery specification is 12V, 2000Ah, load power is 1000W, so the total discharging time is 2000Ah÷(1000÷12×110%)≈21.8 hours.
   Note: The result of formula above is on the basic of discharging rate of 20 hours of the battery, that is, the result is from the discharging current of 2000Ah battery not exceed 100A. When the charging current exceeds this value, the discharging period will reduce. And the quantity of the electricity of the battery may also influence the result.
   Please refer to the specification of the battery manufacturer.

CONNECTION

1. Grounding
   The power inverter has a terminal on the rear 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 AC output receptacle through the internal connecting wire.
   The ground terminal must be connected to the ground wire, which depends on where the power inverter is installed. In a vehicle, connect the ground terminal to the chassis of the vehicle. In a boat, connect it to the boat’s grounding systems. In a fixed location, connect the ground terminal to earth.

Warning:

• To make sure the firmness of the connection. The ground wire must be 14AWG2 (2.08mm ) or even larger.
• Do not operate the power inverter without connecting to the ground. Electric shock may be resulted.

1. Connect to the battery
2. 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 accords with the requirements can be allowed to connect with the inverter.
3. The connecting wire must bear enough current. Depending on the table below, please choose the input DC wire or larger one.

SOFT START TECHNOLOGY

The soft start technology built into this inverter protects the unit from delivering too much AC power at once by gradually increasing the AC voltage pushed out.
To make sure that you are utilizing this feature, turn on the appliance being used before turning on the inverter. This is especially necessary for equipment that has an inductive load or electrical motor.

OUTPUT WAVE FORM

The output wave form of this inverter is Pure Sine Wave, which is much like the one from utility-supplied AC electricity, even more purer; pure sine wave is applicable in most of loads, including electrical equipments, such as Linear Adaptor, switching power supply, transformer, and motor and so on. Comparing with Modified wave form, for inductive loads such as refrigerator and electric fans, pure sine wave form can improve its power factor and the battery’s efficiency and reduce working noises effectively from appliances. For capacitive loads such as adapter of lap-top, pure sine wave can lower the rush current at work and reduce interferences to increase reliability and prolong the life of the product.

TROUBLESHOOTING TIPS

Input DC Voltage
High Input DC Voltage| ● Do not use it when the battery is charging
● Check the rated voltage of the battery and make sure that it is in the allowable range of the input voltage.
Overload| Reduce the load power
Over temperature| ● Cut off the load and let it cool naturally for 10 to 30 minutes.
● Restart it after it resumes to normal temperature. Reduce the load. avoid blocking the vent and improve the ventilation condition.
No AC output voltage?| 1.The power switch is off. 2.Poor contact  with battery.| ● Press the power switch for 1-2 second to turn it on. it is a long press type switch
● Check the cables and make sure they are tightly connected.
Output voltage below 100 V AC?| “True RMS”voltage meter is required to properly measure output voltage of modified wave inverter| ● Test output voltage with a True RMS meter
● Try to maintain the input voltage in the range of rated power
● Change the battery of the meter then test again.
Cannot drive the load?| 1. Load power is too large. Or the actual power of the appliance exceeds nominal power.
2. The starting power is larger than rated power (especially for appliances with motor)
3. Battery is too small.| ● Reduce the load power, or turn on the appliance first, then turn on the inverter.
● Choose a bigger inverter
● Change a bigger battery and ensure fully charged.
Tester indicated “Open Ground”?| This is because it is not connected to a”true Earth ground “, meaning it is not connected to a metal rod stuck in the Earth. it would be impossible to do so in a boat or car while moving. The power inverter DOES NOT and cannot create a true Earth ground on its own.| ● Don’t need the tester to do the Grounding Test.
● Refer to the manual to do the Grounding
Starting alarm ?| The main reason is that ths instantaneous current is too large, which leads to the detection of low voltage and trigger under-voltage alarm.| Please restart the inverter several times.
Got 40V or so while testing inverter’s ground wire and zero line?| This voltage has no meaning, zero line can be ground.| This is normal, there is no current leakage.

If the unit still doesn’t work normally after using all the methods above, it maybe the internal faults of the circuit. Please contact us: [email protected]
