System and method integrating energy management and inverter heat pump

A method of controlling energy consumption of a heating, ventilation, and air conditioning (HVAC) system in adjusting the indoor temperature of a structure connected to an electric utility grid, the method comprising:

• measuring, using a sensor, an indoor temperature and/or an indoor humidity of the structure;
• acquiring a user-determined temperature setpoint and/or a user-determined humidity setpoint using a home energy management system (HEMS) that includes a controller;
• determining an amount of electrical energy stored in an energy storage system storing electrical energy;
• controlling a variable-speed compressor in an inverter heat pump with the HEMS to adjust a compressor speed for the compressor based on at least one of the measured indoor temperature and the temperature setpoint or the measured indoor humidity and the humidity setpoint;
• and
• controlling with the HEMS whether the variable speed compressor is powered by the electric utility grid or the energy storage system.

A heating, ventilation, and air conditioning (HVAC) system for adjusting the indoor temperature of a structure connected to an electric utility grid, the HVAC system comprising a plurality of zones, comprising:

• an energy storage system configured to store electrical energy;
• an inverter heat pump comprising a variable speed compressor controlled by an inverter to operate over an inclusive range of 0% to 100% of a maximum compressor speed for the compressor, the inverter heat pump being electrically connected to the energy storage system and the electric utility grid;
• temperature sensors and/or humidity sensors operable to measure temperature and/or indoor humidity for each zone;
• and
• a home energy management system (HEMS) comprising a controller operatively connected to the inverter heat pump, the controller being programmed to receive inputs comprising, for each zone, an indoor temperature measurement and a user-determined temperature setpoint and/or an indoor humidity measurement and a user-determined humidity setpoint and set a compressor speed of the inverter heat pump in response to the plurality of inputs, the HEMS controlling whether the variable speed compressor is powered by electric utility grid or the energy storage system ;
• and
• a solar energy source electrically connected to the energy storage system, wherein the plurality of inputs further comprise a measurement of generated solar energy,
• wherein the inputs further comprise user-provided zone prioritizations with regard to achieving the user-determined setpoints for the zones.
