EPEVER 30A MPPT Solar Charge Controller Dual Battery 12V/24V Auto 100V Max PV Input - for RV, Camper, Boat, Caravan, Trailer - Compatible with Sealed, Gel, Flooded & Lithium Batteries | Perfect for Off-Grid Power & Mobile Solar Systems

Features: 1.DuoRacer MPPT charge controller is made for charging two batteries(BATT1 and BATT2) at the same time in a solar system, suitable for RV, camping, boat, and so on. 2.Maximum power point tracking technology with ultra-fast tracking speed and the tracking efficiency is no less than 99.5%. Advanced MPPT control algorithm to minimize the MPP lost rate and lost time. The wider range of the MPP operation voltage to improve the PV module utilization. 3.Supports multiple main battery (BATT1) types, including Sealed(AGM), Gel, Flooded, LiFePO4, and Li-NiCoMn. 4.The device recognizes the starter battery (BATT2) system voltage automatically, and trickle charges the battery when the conditions are satisfied. 5.The controller will turn to low-power mode when there is no manual operation for a long time, and the charging conditions cannot be reached, to reduce the loss and battery power waste to enhance the products life. 6.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. 7.Standard Modbus protocol, and RS485 (5V/200mA) communication port for the customer to expand the application area. 8.Auto control function of charging power & charging current limitation(BATT1) Specifications : BATT1 Rated Charge Current: 30A BATT2 Rated Charge Current: 1A rated voltage: 12/24VDC Auto Rated Charge Power: 390W/12V 780W/24V Max.
