New Project: Battery Bank

I want to build a small battery bank in the workshop that will power the fridge/freezer for a few days enough to keep them cold and the food in them good. I can also use this to power my work computers so I can work if needed.

I'll charge the batteries with a charge controller plugged into the wall that will keep the batteries topped off all the time. In case the power goes out and I need to charge the batteries, I'll charge them from the truck engine. It's a generator after all.

I'll be using notes/instructions created by Steven Harris. He's an alternate energy engineer and I really respect him and his knowledge.

I also want to have an inverter that can cool the fridge/freezer when needed.
