Hello!
I have a setup where the Multiplus II 48/5000 is in a garage workshop, fed from the main consumer unit with a 32A supply. It imports from and exports to the grid, and the AC outputs power the garage (I chose this topology instead of grid parallel mostly to provide power assist, but more importantly to limit total input current if I am running stuff in the workshop while the battery is charging).
What I am trying to figure out is the RCD setup.
The output side is easy - 30mA Type A RCD for the load. But what about the input side?
I believe in the UK the code of practice requires an RCD on inverter inputs (may be wrong on that). However, if I put another Type A RCD (even if it's less sensitive) on the input, there would not be discrimination. What are people doing with that? Just no RCD protection for the inverter? Or a time delay (Type S) RCD?
This is in the UK.
Thanks!
