(1) Input overvoltage protection: when the input terminal voltage is higher than 130% of the rated voltage, the inverter shall be protected and displayed (2) Input undervoltage protection: when the input terminal voltage is lower than 85% of the rated voltage, the inverter shall be protected and displayed (3) Input reverse connection protection:

When the input terminals are connected to the negative and positive, the inverter should have protection function and display (4) lightning protection: the inverter should have lightning protection (5) over current protection:

Over-current protection of the inverter, should be able to ensure that the load short circuit or current exceeds the allowable value when the timely action, so that it is free from the damage of the surge current when the working current exceeds 150% of the rated, the inverter should be able to automatically protect (6) output short circuit protection inverter short circuit protection action time should not exceed 0.5s

(7) overtemperature protection, etc

Please kindly take a view and better to understand us:
