Abstract: A system and methods for controlling the supply and distribution of backup electrical power determine when backup power is needed and allocates available backup power among connected devices in a power outage. Batteries may be used as an energy storage subsystem, and may backup a home heating plant and other devices based on a dual set of user-established priorities that may change during power blackouts and brownouts as the amount of stored energy decreases.

Abstract: A system and method for shifting power load on a power distribution network with multiple power loads, each of which draws power from the power distribution network. The system includes a controller communicatively coupled to an energy storage system and power load on the power distribution network. The controller is configured to receive a load-shifting signal, determine a load-shifting procedure, and switch one or more of the communicatively coupled power loads from drawing power from the power distribution network to drawing power from the energy storage system according to a load-shifting algorithm.

Abstract: The invention provides a low electric power-consuming heating or cooling system comprising a DC powered microprocessor-based control system and method and a DC powered electrically actuated zone valve. The control system operates on DC power allowing the heating or cooling system to operate independently of electrical utility grid power, without compromising heating system safety. Electric power consumption is minimized by using very energy efficient DC powered devices and circuit components, and a very energy efficient DC powered zone valve. The control system detects and displays errors in the system and transmits audio-visual alarms when errors are detected, and is also capable of communicating with external computers for data storage and error diagnosis. The zone valve actuator uses DC power and DC electrical and electronic components. The position of the valve is indicated by a sensing system, and valve position is known a priori without rotating the valve.
