I know there's been some questions like this before but I wouldn't mind a check. I have an offgrid only system (currently no AC in and 120V single phase only) with dual 24/3000/120V multiplus in parallel. I am working on my main panel wiring (200A Siemens). I've added a jumper between L1/L2 and have a 60A main breaker. My plan is to have a single ground rod connected to a a ground bus bar (PVs are far away but bond to the EMT then the busbar). My understanding is that the Multis bond neutral to ground in inverter mode. I am a bit unsure how to handle my ground in the panel. Is simply having the ground wire from the multis enough or do I need to create a dedicated ground wire going to the ground bus bar?
