DUAL battery MPPT solar charge controller / regulator with OPTIONAL remote LCD display

Optional remote display control panel MT11 is available at a discounted price when ordering one of these kits or controllers.

It is available as ebay item 334509260512

Model number Epsolar Duo racer 2210N DDS 20 Amp (260 watts MAX solar PV on 12 volt system)

Specification shown for the 10a, 20a and 30a versions available

MT11 remote display and control panel are shown for illustration

Wifi, LAN and PC / tablet / Smartphone connectivity software is available from Epsolar's website, we regret that due to the potential complexity and connection issues we are UNABLE to offer support for this advanced feature. The unit performs very well as a standalone unit.

Product Description

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 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 not included in this listing).

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.

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 MPP lost 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 operation environmental temperature range

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.

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 cannot recognize the system voltage automatically).

②Start battery (BATT2) is the energy storage battery which 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.

A further few points in summary are that the engine starter battery must only be a conventional lead acid / flooded battery and the controller will charge it at a maximum of 1 amp. The older type of Epsolar PWM unit is adjustable ie. 50:50 charge split between the two batteries this latest MPPT range is fixed.
