1. A method for managing an off-grid power supply of a home energy management system, the method comprising:
acquiring data from one or more thermostatic loads connected to the off-grid power supply;
modeling, using processing circuitry, the one or more loads based on the acquired data and on statistics using historical data of the one or more loads;
estimating, using the processing circuitry, a state of charge (SOC) of an energy storage device (ESD) associated with the off-grid power supply based upon forecasted power consumption of the one or more loads, wherein the state of charge is determined using, SOC

  ,, where:
a and b are system parameters,
Pf (t) is a sum of all forecasted load power consumptions, and
PfDG(t) is a total forecasted distributed generator generation at a time t;
determining, using the processing circuitry, an operational status of each of the one or more loads based on at least the estimate of the state of charge of the ESD and a category of each of the one or more loads; and
controlling each load based on the determined operational status.
