Charge two battery banks efficiently with the DuoRacer MPPT Solar Controller, designed to maximize energy harvesting in your solar setup.
Dual-battery charging with automatic BATT2 voltage recognition lets you run two batteries (BATT1 and BATT2) for RVs, campers, boats, and similar systems, with BATT1 chemistry settable via LED/LCD.
Ultra-fast MPPT tracking with guaranteed efficiency not less than 99.5% and a wide MPP voltage range, delivering 20–30% more energy than PWM under varying conditions.
Supports Sealed, Gel, Flooded, LiFePO4, and Li-NiCoMn battery chemistries; the controller optimizes charging for long life and includes auto low-power mode when PV falls below 5V.
Built-in AES control signal for car refrigerators to use surplus solar, IP33 protection, and comprehensive safeguards (overcharge, over-discharge, reverse protection); displays via LED/LCD or MT11 remote meter; supports Standard Modbus protocol.
