I'm building a portable battery box with a 400W inverter, some usb ports, and a couple of 12v cig adapters powered by an optima yellow top and a 48w old arco solar panel. I plan on using this as a standalone unit for trips/camping.
However, I'm not really on the up and up with regard to solar controllers. I'm looking for a cheap one that is reliable and won't over charge my optima. Any suggestions?
