I have an MPP Solar U5648MS inverter (manual here) and 8x second hand ET-M660280WB 280W panels (datasheet here) and I'm not entirely sure what to do about grounding.
I think I'm confusing earth and ground here, but in the inverter manual it says:
WARNING: Because this inverter is non-isolated, only three types of PV modules are acceptable: single crystalline, poly crystalline with class A-rated and CIGS modules. To avoid any malfunction, do not connect any PV modules with possible current leakage to the inverter. For example, grounded PV modules will cause current leakage to the inverter. When using CIGS modules, please be sure NO grounding.
I can't see anything about grounding on the panel datasheet, but my understanding is I should connect the panels/rails to the main earth rod that is pounded into the dirt next to my cabin right? This stops lightning from destroying my equipment?
Sorry for what I'm sure is an elementary question.
