Description
DuoRacer Charge Controller MPPT
DuoRacer MPPT charge controller is made for charging two batteries (shown as BATT1 and BATT2 below) at the same timein a solar system. This controller supports multiple life battery (BATT1) types, including Sealed, Gel, Flooded, LiFePO4, andLi-NiCoMn, which is suitable for RV, Camper, Boat, and so on. The device recognizes the start battery (BATT2) system voltageautomatically, and trickle charges the battery when the conditions are satisfied.
Features
- Maximum Power Point Tracking technology with ultra-fast tracking speed and the tracking efficiency is no less than 99.5%guaranteed
- Advanced MPPT control algorithm to minimize the MPPlost rate and lost time
- The wider range of the MPP operation voltage to improve the PV module utilization
- Auto control function of charging power & charging current limitation(BATT1)
- High quality and low failure rate components of ST, TI and Infineon to ensure the product life
- Digital circuit control of adaptive three-stage charging mode to enhance BATT1 life.
- BATT1 type can be set via LCD.
- Product runs into the low-power mode when there is no manual operation for a long time, and charging conditions are notsatisfied (PV<5V).
- 100% charging and discharging in operationenvironmental temperature range.
- LCD dispiay units selectable.
- AES control signal for car refrigerator to avoid energy waste.
- Standard Modbus protocol, and RS485 (5V/200mA) communication port for the customer to expand the application area.
