Hey everyone pretty new here. I've looked at other questions and can't seem to find the answer. 48 volt system, fixed structure. I have a 10kw nominal solar array, two 150/100 charge controllers, 3 quattro 48/5k/70 split phase setup (planned on 3 phase but somewhat led astray by my vendor so moving on), 3 kilovault Habs 7.5kw LiFePo batterys and a victron smart shunt. Also cerbo gx and digital dispaly. I know that grounding and bonding is a can of worms especially when you talk about lightening/static protection but for now this is only related to the suggested system installation and proper safe operation. I have a series of questions but I'll do one at a time to keep it flowing smooth. I can tell there are quite a few questions on the forum that are somewhat unanswered so I'm hoping this will help me and maybe a lot of others. I want to do what the experts say but also understand why
So..... Do i understand correctly that my negative main bus bar must be earth grounded to provide proper operation of my dc ground fault circuit breaker?
As I said I have several other questions on connection locations and wire sizes but I'd like to ask those based on this answer to create a simpler flow for understanding the how and the why. Thanks again.
