As an important component of the entire power station, the inverter can detect almost all parameters of the power station, from the DC components on top to the grid connected equipment on the bottom. If there is an abnormality, the health status of the supporting equipment in the power station can be checked through the feedback information from the inverter. No mains connection Reason for malfunction: Indicates that there is no connection to the mains or the AC circuit breaker is disconnected, causing the inverter to not detect the voltage of the mains. Solution: Determine whether the power grid has been cut off. If the power grid has been cut off, wait for the power grid to resume supply. If the power supply of the grid is normal, use a multimeter to measure the AC output voltage in the AC voltage range to see if it is normal. First, measure the output port of the inverter and check if there [...]
