  • Three stage charging and temperature compensation for optimal battery charging effectiveness and increased battery life

The SMP100 SolarMax Charge Controller provides up to 100 amps of charging power into battery banks between 24 to 72 Volts from solar panel arrays up to 230 Volts Open Circuit. Our patented MPPT (Maximum Power Point Tracking) algorithm maximizes the power output of the solar array.

Solarmax allows you to use a higher voltage PV array than the batteries you are charging as it is designed to step down the array voltage, allowing greater flexibility in the choice of array for your system.

A PC communications port and software allow viewing and programming Solarmax parameters as well as data logging. A battery temperature sensor (supplied) allows programmable temperature compensation of charging voltage.
