  • Product Details
  • Additional Information

Charge controller EPSolar MPPT DuoRacer 10-30A

Highly efficient, compact and reliable charge controller to use the full power of your solar modules

The MPPT charge controller DuoRacer from EPSolar was specially designed to charge two batteries in a solar system at the same time. Several battery types (Sealed, Gel, Flooded, LiFePO4 and Li-NiCoMn) are supported.

  • MPPT Charge Controller 10A-30A
  • 12-24V system voltage
  • MPP voltage range up to 72V
  • Negative grounding

The MPPT solar charge controller Duo Racer from EPSolar charges two batteries (BATT1 and BATT2) at the same time and is therefore ideally suited for traveling in RV, caravan or car. With the AES interface, the DuoRacer is able to supply excess PV energy to consumers such as a refrigerator.

BATT1 = Battery storage to supply consumers in an island system, household (supports Sealed, Gel, Flooded, LiFePO4, Li-NiCoMn)
BATT2 = Battery storage for vehicles, boats (supports only lead acid batteries)


  • MPPT technology with efficiency =99.5%.
  • Well-developed MPPT control algorithm to minimize MPP loss rate
  • automatic limitation of charging power and charging current
  • LCD display – display and setting of parameters
  • RS485 port, Modbus protocol
  • Compatible with LiFePo4 and Li-NiCoMn batteries
  • Automatic energy saving mode when charging power is too low
  • Wide MPP operating voltage range
  • Numerous protection mechanisms (deep discharge, overcharge, overvoltage protection)
  • AES port for max. utilization of the PV surplus


The monitoring and evaluation of the data can be realised by using the PC software. The controller must either be connected directly to the PC via RS485 cable or via WLAN/Bluetooth with the e-box-WiFi / e-box-BLE.

A converter is required to connect consumers with 12V via the AES port.
