The inverter reports"SPD fault alarm (Warning 202)"

Analysis

    Growatt inverter has SPD on the AC & DC sides. If the machine is subjected to surge or lightning strike, it will play a protective role, and then the lightning protection device of the machine will fail and give an alarm.

Solution: 

    The failure of the SPD will not affect the power generation of the inverter, but it will not benefit the long-term work of the inverter. Therefore, when the fault occurs, you need to contact our after-sales engineer to deal with it.


The inverter reports "Fan fault (Warning 400)"

Analysis: 

    When the inverter reports this fault, it is necessary to check whether the cooling fan on the back of the inverter is rotating. If it does not rotate, you can use external force to rotate the fan blades to see if there is any resistance. If there is, it means that the fan is stuck inside or there is a problem with the bearing, and the fan needs to be replaced.

Solution: 

    As long as it is determined that it is a fan problem, please replace it directly. If all the fans have been replaced and it still doesn't work, there may be a problem with the power supply of the fans inside the machine, please contact our after-sales staff to deal with it.
