I have a switch that I can switch manually between banks but am wondering if anyone has a simple way to charge both banks while they remain isolated from each other. I have seen commercial battery isolators but the diagrams show a separate alternator input into the isolator and then FETS to feed the power to both banks I can't easily isolate the solar inputs from the main battery as I also backfeed through two GTI inverters as well. I am under the weather a bit with RSV at the moment and my brain is fuzzy and not working too well. I have two Kilovacs that I can use, but am wondering about using a diode or a FET. To keep the batteries isolated. Ideally I want both banks to be charged and to be able to switch between banks manually when the weather is not so good for solar inputs. Cheers Pete
