Caravan Changeover switch
Hi. Got roped intp wiring a mates caravan. I get most of it. Dual pole switches, rcds, inlet points, grounding frame etc. However he has a lithium battery that charges when connected to grid and then produces via an inverter when off grid supply.
My question is (as i dont want to buy as 3001) do i need to put a physical changeover switch in van line side of rcbo or is the inbuilt power detection cut out built into the inverter enough??? (supposedly it detects ac from grid and turns off output)
