I am connection a ESS system and got this problem:
For the Multiplus 2 you need to keep AC In N and AC Out N separate or it will not pass ground rele test. How should Multiplus 2 be wired when you add one of those to 3 phase switchboard?
All N of the phases are connected together on the switchboard. Is there any other way to solve this than taking all the N separately on that phase that is connected to Multi?
