EPEVER DuoRacer MPPT Dual Battery Solar Charge Controller 30 amp 12V 24V Auto, Negative Ground Solar Controller for RVs Campers Caravan Boats Trailer
Overview:
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 the solar array under any conditions. The energy utilization in the MPPT solar system is increased by 20-30% compared with the 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 an 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, effectively ensure the solar system's safety, stability, and lifetime.
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
l algorithm to minimize the MPPlost rate and lost time
The wider range of the MPP operation voltage to improve the PV module utilization
The 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 LED/LCD.
Product runs into the low-power mode when there is no manual operation for a long time, and charging conditions are not satisfied (PV<5V).
100% charging and discharging in operation environmental temperature range.
LED and LCD display units are selectable.
AES control signal for car refrigerators to avoid energy waste.
Standard Modbus protocol, and RS485 (5V/200mA) communication port for the customer to expand the application area.
①Life battery (BATT1) is the energy storage battery for powering the household loads in the off-grid system, which supports Sealed, Gel,Flooded, LiFePO4, and Li-NiCoMn batteries (the controller can NOT recognize the system voltage automatically).
②Start battery (BATT2) is the energy storage battery which is usually built in the vehicle for powering the system such as RV and Boat, and only supports lead-acid battery (the controller will recognize the system voltage automatically).
NOTE: the BATT1 and BATT2 must be at the same voltage level.

Can this controller be used to charge 2 12v batteries which are wired together in series?
Answer:
Hi dear customer, this controller can work with 24v battery,2 12v batteries which are wired together in series is 24v, so it is workable.

This works for basic charging of batterys but the chassis battery only charges at 1 amp and only after the coach batterys are full, this can not be changed.

I like how the LCD screen shows you the conversion right on the unit and it turns the extra voltage in to amperage for the batteries. Easy to Use and easy to connect.
