How do I charge two batteries on my camper?

Do you have a camper and maybe want to charge the engine battery with solar as well as your accessories? Well now you can. The Epever DuoRacer does just that. Take a look today. Priced at just £175 in delivery

30A Dual Battery 12v/24v MPPT Charge Controller – EPever DuoRacer DR3210N-DDS – 100VOC PV – LCD Meter

New Dual Battery MPPT series – to charge both your house battery and starter battery from 1 set of panels.

For 12V Solar System: 390W solar panel (100V for max input voltage)
For 24V Solar System: 780W solar panel (100V for max input voltage)

No Fan for silent operation, great for vans, boats or any live in spaces

With built in LCD advanced display and programming screen – with Lithium battery support

DuoRacer MPPT charge controller is made for charging two batteries (shown as BATT1 and BATT2 below) at the same time in a solar system. This controller supports multiple life battery (BATT1) types, including Sealed, Gel, Flooded, LiFePO4, and Li-NiCoMn, which is suitable for RV, Camper, Boat, and so on. The device recognizes the start battery (BATT2) system voltage automatically, and trickle charges the battery when the conditions are satisfied.

The controller adopts the advanced MPPT control algorithm,which will minimize the maximum power point loss rate and loss time,also fast track the maximum power point(MPP) of the PV array, and obtain the maximum energy from solar array under any conditions. The energy utilization in the MPPT solar system is increased by 20-30% compared with PWM charging method. When there is no manual operation for a long time, and the charging conditions cannot be reached, the controller will turn to low-power mode, which reduces the loss and battery power waste to enhance the products life. The system parameters are shown and set by LED/LCD or the MT11 remote meter (Accessory).

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. The controller comes with IP33 protection level, which is waterproof and dustproof. Multiple protection features, including battery overcharge protection, over discharge protection, and reverse connection protection of the PV and battery, which effectively ensure the solar system safety, stability, and lifetime.
