DuoRacer Series MPPT Dual Battery Solar Charge Controller (10-30A) is designed for charging two batteries at the same time in a solar system.
This controller supports multiple life battery types, including Sealed, Gel, Flooded, LiFePO4, and Li-NiCoMn, which is suitable for RV, Camper, Boat, and small applications.
The device recognizes the start battery system voltage automatically, and trickle charges the battery when the conditions are satisfied. The controller adopts the advanced MPPT control algorithm by Epsolar, which will minimize the maximum power point loss rate and loss time and fast track the maximum power point(MPP) of the PV array to obtain the maximum energy from the solar array under any conditions.
The energy utilization in the MPPT solar system is increased by 20-30% compared with PWM charging method. When there is no manual operation for a long time and the charging conditions cannot be reached the controller will turn to low-power mode, which reduces the loss and battery power waste to enhance the products life.

The system parameters are shown and set by LED/LCD or the MT11 remote meter (Accessory). The AES control signal of the car refrigerator is built in the controller, which will supply the surplus solar power to the refrigerator to avoid energy waste. The controller comes with IP33 protection level, which is waterproof and dustproof. Multiple protection features, including battery overcharge protection, over discharge protection, and reverse connection protection of the PV and battery, which effectively ensure the solar system safety, stability, and lifetime.
