SM series MPPT Solar Charge Controller
Product Item ： SM Medium, Large
SM series solar charge controllers are developed for off-grid solar system and battery backup solar system. Maximum Power Point Tracking (MPPT) charging technology can increase 20-30% power usage efficiency of solar panels more than PWM charging technology. Efficiency up to 99% MPPT charging, the adventurer increases battery lifespan by regulating the charge flowing from the solar panels to the battery bank.
