Heat pump system

A heat pump system configured to heat or cool a building is provided. The heat pump system comprises a heat pump circuit. The heat pump circuit includes an evaporator configured to absorb heat from a heat source; a compressor configured to compress a refrigerant and raise its temperature; a condenser configured to release heat from the refrigerant into a sink; and an expansion valve configured to regulate the flow of the refrigerant and lower its temperature before it returns to the evaporator. The refrigerant is configured to flow continuously through the circuit from the evaporator to the compressor, the condenser, the expansion valve, and back to the evaporator to provide the heating or cooling to the building. The heat pump system further comprises a DC battery configured to at least partially power the compressor.
