H-Tronic SL 53 Charge controller PWM 12 V

Lead acid batteries may not be as long as desired without a corresponding charging voltage limitation at solar modules can be connected, otherwise the battery is reaching the gassing voltage can damage the device. This charge regulator switches to achieve the end-of-charge voltage is reached, the charging current and the minimum voltage (13 V). The module is simply connected between the solar panel and battery.This text is machine translated.
