DuoRacer Dual Battery MPPT Solar Controller 30A 12/24V - DR3210N_DDS

DuoRacer MPPT charge controller is made for charging two batteries at the same time in a solar system. This controller supports multiple battery types, including Sealed, Gel, Flooded, LiFePO4, and Li-NiCoMn. The device recognizes the start battery system voltage automatically, and trickle charges the battery when the required.
 
MPPT Solar controllers (Maximum Power Point Tracking) can intelligently regulate the working voltage of solar panels, letting the solar panels always work at Maximum Power Point of V-A curve. Compared with ordinary solar controller, this MPPT controller can increase the efficiency of PV modules by 10% to 30%.
