MPPT Solar Charge Controller ML4830N15

Solar charge controller 48V 30A MPPT support lead acid and lithium battery system for solar RV/Marine application.It is common negative design controller.


1. Advanced double-peak or multiple-peak tracking technology. When the panel has a shadow block or a part of the panel is damaged, I-V curve shows multiple peaks.The solar charge controller can still 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. MPPT tracking efficiency can be as high as 99.9%.
4. Advanced digital power technology raises the circuit energy conversion efficiency to 98%.
5. Support charging gel batteries, sealed batteries, abroach batteries and lithium batteries, etc.
6. 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.
7. Support the instantaneous large current of startup of large capacitance load.
8. Support automatic identification of battery voltage.
9. LED fault indicators can convey system error information, which helps users to quickly identify system faults. It can store historical data for up to 5 years.
10. LCD screen display function: Users can not only check operating data and status, but also modify the controller parameters.
11. The controller is available for standard Modbus protocol and meets different communication needs.
12. 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.
13. With the help of an external battery voltage sampling function, battery voltage sampling is exempted from the effect of line loss, making control more precise.
14. Temperature compensation functions. Charging and discharging parameters can be automatically adjusted so as to extend battery lifespan.
15. TVS lightening protection.
