This is a system to keep up to 4 isolated batteries charged from a single solar/wind power generator. It's using aPIC18F8722 Microcontroller from http://www.futurlec.com/PIC18F8722_Controller.shtml as the controller with software written in C18 from Microchip. Most of the parts came from junk from old equipment at work but I need to buy a full array of solar to make it useful.
The plan is to monitor the batteries and have it select the best one to charge and to alert via RS-232 link any abnormal conditions.
Most of the basic hardware/software is in place for testing. Nothing fancy just relays for switching and some A/D inputs for monitoring voltages and current. For now it's just running outdoor lights and music but the plan is to use an inverter for AC power during the summer for cooling a outdoor room.
