Home grid for improved efficiency of solar energy

A home grid storage and utilization device for electricity generated on-site, the storage and utilization device comprising:

• an electric generator coupled to the home grid storage and utilization device to provide power generated on-site for operation;
• a first reservoir configured to provide a source of cold;
• a cryogenic heat pump coupled to the first reservoir;
• a second reservoir configured to provide a source of heat;
• a first inverter-based heat pump coupled to the second reservoir for concentrating/removing heat from the second reservoir;
• a third reservoir coupled to the first reservoir, wherein heat removed from the first reservoir is exchanged with the third reservoir, and heat in the third reservoir is exchanged with the second reservoir;
• and
• a second operating configuration for the first inverter-based heat pump, to gather heat from ambient air via an outdoor evaporator/condenser coil to concentrate and store heat in the second reservoir.

A method of home grid storage and utilization of energy, the method comprising:

• coupling the home grid storage and utilization device to an electric generator to provide power generated on-site for operation;
• providing a first reservoir configured to supply a source of cold;
• providing a cryogenic heat pump coupled to the first reservoir;
• providing a second reservoir configured to provide a source of heat;
• providing an inverter-based heat pump coupled to the second reservoir for concentrating/removing heat from the second reservoir;
• and
• providing a third reservoir coupled to the first reservoir, wherein heat removed from the first reservoir is exchanged with the third reservoir, and heat in the third reservoir is exchanged with the second reservoir.
