Installation of surge protection at the ac-ouput of solar inverters
It is compulsory to install SPD (surge protection devices) at the ac output of a single phase and three-phase solar inverters. The surge protection module will protect the inverter from high voltages that might be detrimental for the MOSFET and IGBT (internal semiconductors). We recommend the following devices with din-rail mounting.

When using the inverter, the leakage protector must not be used
When the inverter is installed, the three-phase unbalance will generally exceed 50%, so the leakage protector will definitely trip. Here are a few ways: Method 1: There is generally a regulator on the leakage protector, and the regulator can be adjusted to a larger size; Method 2: Replace the leakage protector with a special leakage ...
