High‑efficiency solar charge controller with MPPT technology for maximum energy harvest from solar panels. Offers automatic 12/24 V detection, 40 A load, LCD display, Bluetooth with mobile app for remote monitoring, 2× USB for fast charging, and a temperature sensor for protection and longer battery life. Compatible with GEL and LiFePO4 batteries.
The controller uses advanced MPPT maximum power point tracking, continuously optimizing panel voltage and current for top efficiency even under changing conditions such as partial shading. With support for 12 V/24 V and current up to 40 A, it reliably serves cabin, boat, and RV systems, ensuring fast and safe charging.
The integrated LCD display and Bluetooth with a mobile app enable clear setup and remote monitoring. An external temperature sensor protects the battery from overheating or overcharging. The controller is compatible with GEL and LiFePO4 batteries, ensuring precise charging profiles and longer battery lifespan.
Key benefits:
- Maximum MPPT efficiency – better energy yield from panels than PWM.
- Smart control and app – quick setup, fault and alarm notifications.
- Comprehensive protections – against overcharge, overheating, overcurrent, short circuit, reverse polarity, and deep discharge.
- 2× USB output – convenient charging of small electronics directly from the controller.
- Universal use – ideal for off‑grid, RVs, boats, and cabins.
