Abstract

The present disclosure provides systems and methods for integrating an energy control system with an electrical system having a utility meter connected to a utility grid, a photovoltaic (PV) system, an energy storage system, and a plurality of electrical loads. The systems and methods include determining a site condition of the electrical system, determining a type of backup configuration for the electrical system based on the determined site condition, and determining a location of at least one of a main circuit breaker, the PV system, a subpanel, and a site current transformer with respect to the energy control system based on the determined site condition and the determined type of backup configuration.

First claim

What is claimed is:

1. An electrical system, comprising:
a service panel electrically coupled to a utility grid, the service panel comprising a first feed circuit and a second feed circuit;
a first microgrid system comprising:
a first energy control system electrically coupled to the first feed circuit and a plurality of first backup loads,
a first photovoltaic (PV) power generation system electrically coupled to the first energy control system, and
a first energy storage system electrically coupled to the first energy control system; and

a second microgrid system comprising:
a second energy control system electrically coupled to the second feed circuit and a plurality of second backup loads,
a second PV power generation system electrically coupled to the second energy control system, and
a second energy storage system electrically coupled to the second energy control system,

wherein the first energy control system is configured to transmit electronic data relating to the first microgrid system over a network to a computing device, and the second energy control system is configured to transmit electronic data relating to the second microgrid system over the network to the computing device.

2. The electrical system of claim 1 , wherein the first energy control system is configured to operate in an on-grid mode electrically connecting the first PV power generation system and the first energy storage system to the utility grid and a backup mode electrically disconnecting the first PV power generation system and the first energy storage system from the utility grid.

3. The electrical system of claim 1 , wherein the second energy control system is configured to operate in an on-grid mode electrically connecting the second PV power generation system and the second energy storage system to the utility grid and a backup mode electrically disconnecting the second PV power generation system and the second energy storage system from the utility grid.

4. The electrical system of claim 1 , wherein the electronic data relating to the first microgrid system indicates at least one of a current state of charge of the first energy storage system, a power output of the first PV power generation system, and a load consumption by the plurality of first backup loads.

5. The electrical system of claim 4 , wherein the electronic data relating to the second microgrid system indicates at least one of a current state of charge of the second energy storage system, a power output of the second PV power generation system, and a load consumption by the plurality of second backup loads.
