12/24/36/48V 60A MPPT Solar Charge Regulator for RV Camper, Yacht Marine and Off-Grid Battery System
Product description
The MPPT solar charge controller manages battery charging from solar panels. Its built-in MPPT maximum power point tracking module can detect the output voltage of solar panels in real time and track the optimal voltage and current (VI) values, enabling the system to charge the battery at maximum power output.
Used in solar photovoltaic systems, it coordinates the operation of solar panels, batteries and loads, and protects batteries against overcharge and over-discharge.
- Advanced dual-peak or multi-peak tracking technology, when the panel is shaded or part of the panel is damaged, the I-V curve will come into being multiple peaks, and the controller can still accurately track the max power point.
- Built-in maximum power tracking algorithm, which is about 20% higher than the traditional PWM charging efficiency, can significantly improve the energy utilization efficiency of PV systems.
- Up to 99.9% MPPT tracking rate.
- Supporting gel batteries, sealed batteries, open batteries, lithium batteries,etc.
- Current-limit charging mode. When the power of the panel is overload and the charging current is greater than the rated current, the controller automatically reduces the charging power to operate it at the rated charging current.
- Support battery voltage automatic identification.
- LED fault indication, LCD abnormal information indication, convenient for the user to determine the system fault.
- LCD screen shows device running data and status, and supports controller parameter altering.
- Standard MODEBUS protocol to meet the communication needs on different occasions.
- External Bluetooth, mobile phone app connection, to view solar charging and battery storage in real time.

Relevant Information
The two mainstream technical routes for solar charge controllers are PWM and MPPT, with distinct working principles. PWM controllers regulate charging current through rapid on-off of analog or digital circuits with a fixed duty cycle. Their core logic is to force the photovoltaic array voltage to clamp to the battery terminal voltage, making the two voltages basically equal. As a result, energy loss is mainly caused by the waste of excess voltage. In contrast, MPPT controllers are equipped with a built-in DC-DC conversion circuit. They sample the voltage and current of photovoltaic modules in real-time, track the maximum power point on the I-V curve through professional algorithms, and dynamically adjust the output voltage and current. This design allows MPPT controllers to efficiently convert the maximum power of photovoltaic modules into usable energy for batteries, converting excess voltage into additional charging current, thus achieving higher energy utilization efficiency.
