This 10a charge controller is compatible with 12V 24V system. Fully 4-stage PWM charging (Boost, ABS, Equalization, Float), power MOSFET is used as electronic switch without any mechanical switch and equipped with quality STM 8 microprocessor. industrial to extend your battery life cycle. Backlit LCD display PV/Battery/Charge charge and discharge parameter. Dual USB can give your electronic product maximum 5V 2.5A. This solar controller is suitable for lithium-ion/lithium iron phosphate/lead-acid batteries (OPEN, AGM, GEL) with multiple charging timers (charging must be DC). It has a wide range of applicability and automatically identifies day/night. To protect your battery life, once the battery voltage drops below 8V, the solar controller will automatically shut down. PWM charge controller protection: dual MOSFET reverse current/overheat/undervoltage discharge/short circuit/open circuit/overload/overload protection.safer for home, industry, commercial, etc.
