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.
This controller can be widely used for RV, household system, field monitoring and many other applications.

1. Warning:When the lithium battery of 12V is used and the BMS is protected, the lithium battery voltage may increase up to 17V(DR*106N) or 35V(DR*206N,DR*210N) which may damage the load, so please consider the load’s voltage.
2. At minimum operating environment temperature.
3. At 25℃ environment temperature.
4. The Temperature compensate coefficient is zero and not changeable when the main battery type is lithium battery.
5. AES port which output is 12V/200mA and RS485 Port which output is 5V/200mA are independent of DR1106/2106/3106N models, the AES port output voltage is the battery voltage. The above two ports of DR1206/2206/3206/2210/3210N modelsshare the power of 5VDC/Max. 200mA
6. The communication baud rate can only be set via PC software.
7. The LCD backing time can only be set via PC software, setting range is 0~999S and the 0s means the LCD is on all the time.
