Inverter for Solar Panel System

700 watt to 6000 watt off grid inverter system


In the photovoltaic off-grid system, the power of the off-grid inverter is generally confirmed according to the load type and power of the user.

The load is classified into the following types according to the impedance property: Resistive load, inductive load, and capacitive load. The resistive load: The load with no phase difference between current and voltage is a resistive load, such as the electric cooker, bulb, electric furnace, electric soldering iron and so on. The inductive load: It is an inductive load if the current is one phase difference lagging behind the voltage, such as the washing machine, air conditioner, refrigerator, water pump, kitchen ventilator, load with motor, transformer, relay, compressor and so on. The capacitive load: It is a capacitive load if the current is one phase difference leading ahead the voltage, such as the compensation capacitor, computer, television and other household switching power supplies. The start-up power of the motor and other inductive loads is 5-7 times the rated power. In calculating the power of the solar inverter, the start-up power of these loads should be taken into account.

Without issue for over 7 months
I have been using this 700 watt off grid solar inverter without issue for over 7 months. Instructions are clear, easy to program. I'm very satisfied with this purchase.

The off-grid solar inverter works well
Good results. Most functions have been evaluated and tested using oscilloscopes, power analyzers, and bench testing. The internal battery current indication is down 2%, but expected. The conversion efficiency is well above 90%, and the fans are turned off or off during periods of low power consumption.

Great off grid solar inverter
I am using an off grid solar inverter for about 3 months now, it is a very good inverter! I use it in a van to power a 1000-watt induction cooker, and the inverter runs completely quietly and will not disturb me. If it is hot in summer, the internal fan may be turned on for a few minutes.
