PWM85 - Microampere PWM Solar Charge Controller
The PWM85 is finally using less than 1mA of current in standby!
The PWM85 is a simple pulse width modulation solar charge controller based on Julian Illet's PWM5, but the 85 is based on a ATTiny85 and can be programmed through the Arduino IDE.
It can connect up to 100 watts of solar (36 cell) and will charge lead acid and LiFePO4 cells to 13.5 volts. However if you would like to adjust that charging voltage, then drop by the github repo and download the code.
