EPEVER DuoRacer Dual Battery MPPT Charge Controller 60V 30A 12V DDS




The EPEVER DuoRacer series has dual battery charge controller supports trickle charging (max. 1A) to the start battery (BATT2) of vehicles. The EPEVER DuoRacer series is perfect for off-grid solar system such as motorhome, RVs, campers, boats, and so on. It charges the main battery (BATT1) for living, and supports trickle charging (max. 1A) to the start battery (BATT2) of vehicles at the same time.


Product Highlights

  • 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
  • Charging power & charging current limit function (BATT1)
  • High quality and low failure rate components
  • Digital circuit control of adaptive three-stage charging mode
  • BATT1 type can be set via LED/LCD.
  • Product runs into the low self-consumption mode if PV voltage is lower than 5V and there is no manual operation for some time.
  • 100% charging and discharging in operation environmental temperature range.
  • LED and LCD display units optional
  • Standard Modbus protocol, and RS485 (5V/200mA) communication port for the customer to expand the application area.


Bat1 can be a lead-acid battery and lithium battery, and Bat2 has to be the lead-acid battery.
