July 7, 20215 yr I have an a current installation of a 8-KW Deye inverter with 16 420-W solar panels. I have installed an external earth leakage breaker but I saw a manual on another Deye inverter that says the inverter has a built in earth leakage protection, and that if I install an external earth leakage it must be set to 300-mA. I further checked the inverter manual and noted that it has a normal AC breaker between the Grid and the inverter (and NOT EARTH Leakage). My worry is that when you have bypassed the inverter, the earth leakage must be available for Grid supply, and if you remove it then you are defeating the whole protection purpose.
