The PowMr POW-Boost 10A is an advanced MPPT solar charge controller designed for high-voltage battery systems (24V to 72V). It features boost charging capability, allowing it to increase the voltage from a low PV source (15–60V) to match higher system voltages. With up to 99.9% MPPT tracking efficiency, a three-stage charging algorithm, and wide compatibility with lithium, gel, and lead-acid batteries, it ensures safe, efficient, and intelligent battery charging in off-grid solar systems.
