Our controller utilizes cutting-edge Maximum Power Point Tracking (MPPT) technology. This smart feature constantly finds the optimal voltage point for your solar panels, boosting their power output by up to 30% when compared to older PWM controllers. It's truly a game-changer for maximizing your energy harvest. Plus, it's incredibly versatile, compatible with a wide range of solar panel voltages, from standard 12V/24V off-grid panels to high-voltage arrays up to 150V. This is especially beneficial when your solar panel voltage is much higher than your battery's, ensuring every watt is efficiently captured.

Enjoy complete peace of mind with a full suite of electronic protection functions built right in. This controller includes robust safeguards against reverse current, over-charging, deep discharge, solar panel over-voltage, overload, short circuits, and reverse polarity. It even features smart self-diagnostic capabilities, pinpointing and highlighting any system errors with advanced fault-targeting technology. For immediate alerts, an optional audible alarm is available to notify you of any system failures.

Setting up is simple as the controller automatically recognizes both 12V and 24V battery systems. Bright LED indicators keep you informed about the charging status and battery condition at a glance. A standout feature is its 40A current limiting function, which means you can add more solar panels to your system in the future without needing a new controller. The rugged die-cast aluminum design ensures excellent heat dissipation, keeping your system cool and extending its lifespan.

This model offers superb communication options, giving you flexible ways to monitor and program your solar charge controller's parameters:

• Connect to a remote meter MT50 with an LCD screen to view system performance and manually adjust settings.
• Connect a Wi-Fi module to create a Wi-Fi network, allowing you to monitor and adjust charging parameters and controller settings via a free mobile app (available for Android and iOS).
• Use an RJ45 to USB cable to connect directly to a Windows PC or laptop. Our free 'Solar Station Monitor' software lets you monitor and adjust parameters with ease.

By using any of these methods, you gain full control over your charging parameters, allowing you to fine-tune settings to match your specific energy needs. Additionally, the controller features a built-in temperature sensor and intelligent heat-dissipating design. A dedicated socket for connecting a remote temperature sensor is also available, ensuring highly accurate battery temperature measurements and optimized charging.
