Hi I have a Multiplus 2 (3kw 12 v to 240v UK) I’m installing in a 1966 Citroen HY van which is being used as a Coffee van , I’m obviously wanting to run all appliances during day off the 12v battery bank but of an evening during battery recharging stage off residential 240v AC I’m wanting the fridges to stay live through the 240 AC in. Does this configuration mean that the circuit for the fridges has to be wired to AC 2 output and I’ll have to have a separate circuit and plug the fridges from AC1 circuit to AC 2 circuit every night or am I missing the trick here??
