Maximize your solar array's output with this 20A MPPT charge controller engineered for 12V and 24V off-grid systems. Advanced maximum power point tracking delivers 99% tracking efficiency and 98% peak conversion efficiency, harvesting usable energy even on overcast days when panel output fluctuates. Automatic 12V/24V voltage detection eliminates manual setup, while broad compatibility with sealed, gel, AGM, flooded, and iron-phosphate deep-cycle storage banks makes this controller a versatile fit for a wide range of off-grid applications. Nine layers of electronic protection—including reverse polarity, overcharge, over-discharge, overload, short-circuit, TVS lightning, over-power, over-temperature, and reverse-current safeguards—keep your system running safely around the clock.
