Features 1Advanced MPPT Charging Technology: The solar charge controller uses advanced MPPT charging and power point tracking technology. With the same power solar panels, these technologies enhance the charging efficiency of the panels by 10% to 30%, making it a highly effective charging solution. 2DC Load Output Support: The MPPT solar charge controller supports resistive load outputs only, ensuring no large surge currents during operation. This makes it perfect for use with LED lights, cameras, and various precise instruments providing a steady and reliable output. 34 Working Modes: Supporting four distinct modes, manual, light control, light control on plus timing control off, and real time control, the solar charge controller offers great flexibility to cater to diverse user requirements. 4Comprehensive Charging Guard: Providing comprehensive protecting mechanisms including short circuit prevention, overcurrent prevention, and reversed polarity prevention. This makes the solar charge controller exquisitely safe, reliable, and worry free for its users. 5Wide Battery Compatibility: The solar battery charge controller features a safer negative ground design and is compatible with a range of batteries. It supports sealed, gel, flooded, and Li (LFP) batteries with preset charging parameters, and other batteries can be customized as per needs, ensuring wide applicability.
