DuoRacer Dual Battery MPPT Solar Controller 20A 12/24V -DR2210N_DDS

The Dual Battery MPPT Solar Charge 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. The controller features a low-power mode, which reduces standby current when the unit is idle preventing power waste and helping to enhance the products life. The system parameters are shown and set by LED/LCD or the MT11 remote meter (Accessory).
Monitoring of the system can be made easy with the optional remote meter or via Apple & Android smartphones, tablets, macbooks and other devices, using the optional Bluetooth Adapter.
