Epever 20A MPPT Solar Controller DC 12V/24V For RV/Boat Regulator Dual Battery
Overview:
DuoRacer MPPT solar 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 into 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 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.
- The 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 displays 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 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.
