DuoRacer 30A MPPT Charge controller
The DuoRacer MPPT charge controller is made for charging two batteries (shown as BATT1 and BATT2 below) at the same time in a solar system. This controller supports multiple life battery (BATT1) types, including Sealed, Gel, Flooded, LiFePO4, and Li-NiCoMn, which is suitable for an RV, Camper, or Boat, and so on. The device recognises the start battery (BATT2) system voltage automatically, and trickle charges the battery when the conditions are satisfied.
The controller uses an advanced MPPT control algorithm, which will minimize the maximum power point loss rate and loss time, and fast track the maximum power point(MPP) of the PV array, and obtain the maximum energy from solar array under any conditions. The energy utilisation in the MPPT solar system is increased by 20-30% compared with PWM charging method.
