Once upon a time, I found a couple websites that had instructions and illustrations on how to build a emergency power battery bank. I believe it was four very large Ah batteries banked together and hooked to a controller, charged by a trickle charger or a solar charger or the combination of both. It was housed in a vented rubbermaid container and had DC power points built in and a DC to AC inverter mounted to the top. I can't for the life of me find those pages.
Has anybody seen this done or does anyone know where I can find these or any instructions on how to construct this?
Do you connect the batteries pos to neg or pos to pos neg to neg?
Any help would be appreciated.
