Not all over my head!
Enjoying the great replies and reading them closely. Sounds like the consensus is that I can get away with a much smaller set up. I am intrigued by the GC battery idea, but think I'm going to go with the simpler project of swapping 12v batteries with smaller/cheaper new ones. Then at least I'll keep a charge overnight!
