Thank you. I'll certainly enjoy looking at your wiring diagram for clues regarding circuit changes.
I use a Morningstar TriStar solar charger (60 Amp, 24 volt) for the charging of the batteries. Thus I want to disable the UPS charging circuit.
There was a point made regarding the UPS installed relays and that has given me an idea. I'll just have to look at the circuit again. Does anyone have schematics for UPS's?
