EPever DuoRacer MPPT 10A 20A 30A Solar Charger and Discharger Controller 12V 24V Auto Dual Battery Regulator for RV Camper Boat

US $90.10 - 144.07
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 themaximum 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 conditionscannot 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.

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 algorithm to minimize the MPPlost rate and lost time

The wider range of the MPP operation voltage to improve the PV module utilization

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 operationenvironmental temperature range.

LED and LCD dispiay units selectable.

AES control signal for car refrigerator to avoid energy waste.

Standard Modbus protocol, and RS485 (5V/200mA) communication port for the customer to expand the application area.

Life 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).

Start battery (BATT2) is the energy storage battery which usually built in the vehicle for

powering the system such as RV and Boat, and only support

NOTE: the BATT1 and BATT2 must be at the same voltage level.

Structure

Specification:

AES Signal Output Port Instruction

AES signal port of DR1206/2206/3206/2210/3210N-DDB/DDS

The AES signal port and RS485 port share the power of 5VDC/Max.200mA.,connect the

accessories when connect the refrigerator, refer to the below picture.

NOTE:The AES signal port and RS485 port share the power of 5VDC/Max.200mA. The MT11

power consumption is 13mA when it is ON, and 4mA when it’s off.

AES port working principle
 The AES signal turns on after the BATT1 voltage reaches the boost charging voltage or equalize charging voltage for 5 mins.

 The controller will check if the BATT1 voltage is lower than the boost charging voltage or equalize charging voltage every 5 mins (This value is the judgement delay time for turning off the AES signal which can be set via PC software, default

as 5 mins, ranging form 0 to 999 mins) , the AES signal control will be turned off if it meets the conditions for 5 times.

Optinal accessories

Note: If eBox-WIFI-01 or eBox-BLE-01, you need a extra cable of CC-RJ45-3.81-150U

Remote Meter(Model :MT11)
The MT series remote meter is an accessory which is compatible with the DuoRacer series controller. It can monitor the running data and working status of the controller via the remote meter. The remote meter can browse the controller’s parameters, set the battery typeand temperature unit, and clean the generated energy.It is suitable for RV, Camper, Boat, and so on.
