Inverter Use Notice
1. The starting power of inductive load electrical appliances shall be at least three times of the rated power of the electrical appliances. If the starting power exceeds the inverter power, the inverter may be damaged. Please select a suitable model before purchasing.
2. Please connect the circuit correctly according to the instructions, and install switches for each circuit.
3. Starting sequence: first turn on the battery switch, start the inverter, and turn on the PV, mains and load switches.
4. Shutdown sequence: turn off the switches of load, PV and mains, turn off the inverter, and finally turn off the battery.

FAQ:
Q:Whether it can be connected to the grid?
A:PV gives priority to power supply to the load, and extra to charge the battery, and more can be integrated into the grid (need to be based on local government policies)
Q: Is it possible to use PV, battery, grid supply at the same time?
A: YES. The default PV priority mode, when the PV input is insufficient, the battery and utility will be used.
Q: Can inverters be connected in series or parallel?
A: NO.
Q: Can the utility be used to power the inverter when there is no sun?
A: YES.
Q: How to choose the power of the inverter according to the household appliances?
A: If household appliances contain inductive load appliances, such as refrigerators, washing machines, air conditioners, etc., the power of the inverter is at least three times the total power of the inductive load appliances, otherwise the appliances may not be able to start.
Q: How many solar panels need to be connected?
A: In order to start the inverter normally, the voltage of the solar panel is recommended to be 300V-400V, The maximum does not exceed 500V.
