The Neutral Full Power MPPT Solar Charge Controller GM-D (50A) offers cutting-edge MPPT (Maximum Power Point Tracking) technology, delivering an outstanding 98% energy efficiency, far superior to traditional PWM controllers that offer up to 70% efficiency. The GM-D 50A model maximizes energy harvesting from solar panels by precisely tracking the optimal power point, even when sunlight conditions are fluctuating. Whether you have a 12V or 24V solar system, this controller ensures that your solar setup operates at its peak performance.
With its ability to support up to 650W for 12V panels and 1300W for 24V panels, the GM-D 50A is a powerful solution for residential and off-grid solar applications. This 50A MPPT controller is equipped with a dual fan cooling system and a heavy heat sink, ensuring efficient operation under high temperatures. It also features multi-peak tracking technology, which ensures the highest energy yield even in areas where sunlight varies throughout the day.
The built-in LCD display gives users real-time data on solar panel voltage, battery status, current flow, and overall energy output, enabling precise energy management. It’s compatible with various battery types, including lead-acid, lithium, and LiFePO4, allowing for customizable battery settings to suit different power needs.
