Charge controller with ultra-fast maximum power point tracking, Especially under cloudy skies, when light intensity changes continuously, an ultra-fast MPPT controller will improve energy collection by up to 30%. With load output, you can prevent the battery from over-discharging by connecting all loads to the load output, and disconnect the load when the battery is fully discharged. Flexible charging algorithm and extensive electronic protection, with internal temperature sensor, compensates for absorption and float charging voltages.
