12/24/36/48V 30A 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
Conversion efficiency refers to the ratio of effective charging power to photovoltaic input power. PWM controllers typically range from 70%-80%, while MPPT controllers can reach 95%-99%. For every 1% improvement in efficiency, the annual revenue increases synchronously. MPPT tracking efficiency is the ratio of the actual maximum power point tracked to the theoretical maximum power point, with an industry benchmark of ≥99.5%, which determines the actual power generation in complex lighting scenarios. Rated voltage adapts to battery system levels, commonly 12V/24V/36V/48V/96V/192V/384V, and must be strictly matched with batteries to avoid system faults. Rated current, usually 10A/20A/30A/60A/100A+, directly affects charging speed and system power limits. Input voltage range covers the open-circuit voltage of photovoltaic modules, determining compatible module types and series quantity. Protection grade for outdoor products is IP65+, while marine/vehicle products require IP67+. Communication interfaces like RS485/CAN/Bluetooth enable remote monitoring, the core of intelligent operation and maintenance.
