The OpenEGrid environment and eco-system consists of two primary components:
This is the on-site component that lives at the physical location where Micro-Grids, DERs (Distributed Energy Resources), or other Renewable Energy/Energy Efficiency components need to be deployed, monitored and controlled. These Gateways are also the component that facilitates implementation of Policy such as California Rule 21, DER Aggregation, creation of VPP (Virtual Power Plants) or just simply Demand Response capabilities.
The OpenEGrid Cloud is the massively scalable platform that communicates with the OpenEGrid OMS systems for various purposes such as Micro- Grid design, master control and coordination functionality, data repository, data analytics, and deployment of OpenEGrid cloud based services such as California Rule 21, IEEE2030.5 and IEEE1547 Aggregation services.
The OMS is available in three models, customized for various deployment scenarios
OMS SU Lite - Residential indoor use
The SULite series of OMS that is capable of controlling and monitoring a single inverter, and it's surrounding DERs. The SULite is best suited for less harsh and more forgiving environments such as indoor deployment of smaller systems, for example a residential Micro-Grid that has an inverter installed in a garage or other Micro-Grid equipment controlled from an equipment room.
OMS SU - Commerical applications
The SU series of OMS is also meant for controlling and monitoring a single inverter, but it is designed for harsh, less forgiving environments such as a solar farm using a central inverter approach, where the inverter lives outdoor, on a concrete pad, exposed to the elements. While the OMS-SU is not itself outdoor rated, it is capable of withstanding larger temperature variations and harsher physical conditions such as dust and humidity.
OMS MU - Large outdoor systems
The MU series of OMS is designed for and capable of controlling and monitoring multiple inverters, and their surrounding DERs. The MU series of OMSes are housed in a self-contained NEMA 3R rated enclosure and are capable of being deployed outdoor or in environments that might need to connect with several inverters and surrounding DERs. A solar farm deploying dozens of string inverters, or a multi-storied building with lighting and thermostats deployed in several different zones are examples.
