The Solar Hybrid Hot Water Controller has a CPU specially programmed for Maximum Power Point Tracking (MPPT) and continually adjusts during the day to get the most power from the Solar Panels. MPPT is especially needed in the mornings, afternoons or cloudy days to keep the most power pumping into the heating element at all times. You can try hooking up your solar panels direct, but without MPPT you will get little heat for your investment and have other problems.
