Looking for some advice again from wise heads here.
summery of setup:
I have 3 x growatt SPF 6000 ES in single phase parallel (230v EU).
I have 4 x 14.3kw battery banks paralelled with centalised busbar.
Solar and battery working but I have not connected Utility back or loads yet.
Id like to add a transfer switch, but its not essential
Im unsure on breaker types and positioning. Growatt manual is vague at best "Before connecting to AC input power source, please install a separate AC breaker between inverter and AC input power source."
I have attached a schematic of what I think I should do. I thought to use type B MCB's on the live only.
Does this all look safe and right?
Should these be 2 pole and break the neutral also?
Should there be an RCD or RCBO somewhere between utility and ac in ouf inverters?
Do the paralellel block positioning make sense?
thanks
