Claim One:
1. A method of offset demand monitoring in a distributed energy resource energy storage (DER-ES) apparatus, comprising steps for: providing one or more communication protocols to allow one or more components of one or more DER-ES apparatus to communicate with each other without a host computer; implementing one or more steps for one or more mode selection management methods via a gateway controller computer system associated with one or more DER-ES apparatus at a user site; measuring a user site demand by reading one or more site loads; selecting an active mode corresponding to the requested mode of the highest priority program; implementing the active mode of the highest priority program to coordinate one or more energy resources in one or more local events; housing an inverter in a common enclosure within the distributed energy resource energy storage apparatus; reacting to demand conditions to match the site demand measurement with an inverter power output; controlling the inverter to dispatch the matching power output calculating one or more offset demand amounts associated with reducing one or more grid demand amounts; calculating one or more offset demand amounts associated with avoiding one or more grid power export amounts; selecting one or more offset energy demand amounts; communicating with one or more network connected DER-ES apparatus; reading one or more site loads from one or more site meters wherein the site configuration is selected from one of a group consisting of a site with a main load panel only, a site with a main load panel plus a critical load panel, and a site with neither a load panel or a critical load panel; managing one or more offset demand amounts related to one or more distributed energy resources; charging one or more storage devices in a storage appliance from one or more renewable energy source charge controllers, wherein the storage appliance and charge controllers are integral to an associated DER-ES apparatus, and wherein charging the one or more storage devices continues until each of the one or more storage devices are fully charged, unless an amount of renewable energy power generated at the user site location is less than the required amount to charge the one or more storage devices, at which time the one or more storage devices receive power from the grid until fully charged; measuring demand on one or more load panels to determine a DC bus support load power requirement and an AC inverter grid side power requirement, wherein the difference in power requirements determines an amount of offset energy demand, and limiting the export of renewable energy generation to the grid by measuring and storing renewable energy power generated in the DER-ES apparatus; dispatching the renewable energy power in excess of site demand when the site demand measurement is more than or equal to a desired change amount; calling an internal InvertToAC function in a gateway controller associated with the DER-ES apparatus to increment power output of an inverter housed within the DER-ES apparatus.
