A charge controller (also known as a charge regulator) is the link between your solar panel and battery. It ensures safe battery charging, prevents overcharging, and extends the lifespan of your entire off-grid system. At UMATECH , you can choose from efficient MPPT regulators from 10 A to 60 A, as well as affordable PWM models for smaller setups.
Why MPPT? Maximum Power Point Tracking continuously analyzes your panel's voltage curve and harvests up to 30% more energy than a standard PWM controller—especially on cold or cloudy days. Our top-of-the-line models support 12V, 24V, and 48V battery banks and accept PV voltages up to 150V, allowing you to connect panels in series and minimize cable losses.
All controllers feature multiple protections against reverse polarity, short circuits, high temperatures, and overvoltage. You can view charging current, panel voltage, and battery status in real time via the built-in LCD screen or the Bluetooth app. Integrated charge profiles for AGM, GEL, LiFePO₄, and even user-specific curves make fine-tuning a breeze.
Simply mount the controller in a well-ventilated location, connect the MC4 cables and battery clamps, and you're done—no programming required. For camping, boats, or tiny houses, we also offer IP67 waterproof controllers with Anderson plugs, ideal for quick plug-and-play installation.
