Nearing the end of my solar install (major works due to ground mount being over 60m away) and ive been pondering about options for the backup supply from the batteries. I obviously want to keep my 5 freezers and 3 fridges going in the event of a power cut (very common here in the sticks) but the 20A supply isnt really man enough for day to day usage when i use other equipment such as various tooling and large valve amplifiers.
So for days of heavy usage, i was thinking of a changeover switch with supplies from the batteries and the mains via henleys. (Please see picture) Question is, do i need the supply from the henleys fused? or can i just feed directly into the switch? The backup supply to the house is protected at the battery end of things via an RCBO on a consumer board and an MCB directly off the inverter. So can i feed this directly into the switch as well? The feedout supply from the switch will be going into a consumer board with an RCD incomer.
As ever thanks for any advice.
