The EG4 6000XP manual states the inverter has "safety features such as PV Arc Fault Protection and PV Ground Fault Protection." Does anyone know how these are implemented. If it detects a fault, Does it stop drawing power from the PV array? Does it trigger RSD? Does it simply post a fault warning in the inverter display? I find no discussion of AFCI or GFDI implementation in the EG4 literature.
Especially; does the EGC from the solar array need to be connected to the 6000XP PE bus for PV arc fault protection and/or PV ground fault protection to work (rather than running the EGC directly to the main load center ground bus and the "One" grounding electrode for the system)?
Thank you.
