| DuoRacer Dual Battery MPPT Solar Controller 20A - 12/24V |
|
| DuoRacer MPPT charge controller is made for charging two batteries at the same time in a solar system. This controller supports multiple battery types, including Sealed, Gel, Flooded, LiFePO4, and Li-NiCoMn. The device recognizes the start battery system voltage automatically, and trickle charges the battery when the required. |
|
| MPPT Solar controllers (Maximum Power Point Tracking) can intelligently regulate the working voltage of solar panels, letting the solar panels always work at Maximum Power Point of V-A curve. Compared with ordinary solar controller, this MPPT controller can increase the efficiency of PV modules by 10% to 30%. |
|
| Features |
|
| Maximum Power Point Tracking technology with ultra-fast tracking speed and the tracking efficiency is no less than 99.5% guaranteed |
| Bluetooth (eBox Bluetooth Adapter required) |
| 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. |
| LED and LCD display units selectable. |
| Standard Modbus protocol, and RS485 (5V/200mA) communication port for the customer to expand the application area. |
