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.
