Charge Controller for Off-Grid Systems
This is a charge controller for use with solar PV, wind and small scale hydro systems. It is designed for off-grid battery based systems at voltage levels of 12 or 24V DC and currents up to 20A DC. It can be used as a series controller, a shunt controller and as a Low Voltage Disconnect, with no change in the hardware.

It is not a MPPT device, although that could be added later. Its is designed to be relatively simple, robust, using through-hole components.
It is based upon the ATTiny84 microcontroller and code is written and uploaded via the Arduino IDE.
This is a work-in-porgress. A schemaic and better images will be uploaded soon.
