Abstract: Photovoltaics and an MPPT DC/DC converter powers a DC bus of a controller. It uses an electric heat pump to heat a mass like water, and also has a resistive heating element to heat the mass. A microcontroller controls a variable frequency (VFD) motor drive to power the electric heat pump when sufficient solar power is available to run the heat pump and uses the resistive element to heat the thermal mass when insufficient solar power exists for the heat pump or when excess solar power is available. A controller has an MPPT input for solar power and a VFD to provide power through an output to a heat pump-based water heater and an output to power a resistive water heating element. A microcontroller determines solar power available and runs the heat pump when possible and the resistive element when insufficient power is available or when excess power is available.
