High-Efficiency Technology solar charge controller adopts advanced Maximum Power Point Tracking technology to significantly improve charging efficiency. It continuously monitors solar panel output and battery status, automatically adjusting the charging point to harvest more power from your solar array compared with traditional PWM controllers. Wide System Voltage Compatibility: 12V / 24V / 36V / 48V Fully compatible with 12V, 24V, 36V, and 48V battery systems. The controller automatically identifies and adapts to the system voltage (when properly wired), offering flexible use in residential, commercial, and mobile solar applications without requiring multiple different controllers. Real-Time LCD Display & Easy Operation Equipped with a clear LCD screen that shows real‑time system information such as battery voltage, charging current, load status, and operating mode. Intuitive buttons easy to set parameters, check system status, and perform on‑site adjustments without additional tools. Wide Application Scenarios Ideal for solar in RVs, motorhomes, camping setups, cabins, boats, small off‑grid houses, communication base stations, security systems, and other DC power supply scenarios. Can be used as the core controller in both new installations and system upgrades. Design for Various Environments Robust housing and optimized internal layout help improve heat dissipation and reliability. Suitable for use in off‑grid homes, RVs, boats, cabins, farms, and remote monitoring stations where stable and continuous solar power is required.
