MPPT RV Solar Charge Controller MC series 20A-50A

MC series is MPPT charge controller with LED display.The controller can be connected with external LCD screen or Bluetooth module so that users can not only check operating data and statu,but also modify the controller is perfect for RV systems and solar power system.


1. The advanced dual-peak or multi-peak tracking technology: When the solar panel is shadowed or part of the it breaks down, there will be multiple peaks of the I-V curve. The controller is still able to accurately track the maximum power point.
2. The maximum power point tracking algorithm can significantly improve the energy utilization efficiency of photovoltaic systems. The charging efficiency is 15% to 20% higher than the conventional PWM method.
3. Automatic charging voltage regulation function: When there is battery open circuit or lithium battery BMS overcharge protection, the controller battery terminal will output at the rated charging voltage value.
4. MPPT tracking efficiency is up to 99.9%.
5. Advanced digital power technology raises the circuit energy conversion efficiency to 98%.
6. Support charging lithium batteries, gel batteries, sealed batteries and abroach batteries, etc.
7. The controller features a limited current charging mode. When the solar panel power exceeds a certain level and charging current is larger than the rated current, the controller will automatically lower the charging power and bring the charging current to the rated level.
8. Support automatic identification of lead-acid battery voltage.
9. The controller can be connected with LCD screen or Bluetooth module so that users can not only check operating data and status, but also modify the controller parameters.
10. The controller is available for standard Modbus protocol and meets different communication needs.
11. The controller has an overheat protection mechanism. When the temperature exceeds the set value, the charging current will decline in linear proportion and discharging will be shut off so as to curb the temperature rise of the controller and keep the controller from being damaged by overheat.
12. Featuring a temperature compensation function, the controller can automatically adjust charging and discharging parameters in order to extend the lifespan of battery.
13. Solar panel short circuit protection, battery open circuit protection and TVS lightening protection etc.
