Battery storage (without a solar electric system) for a landlord-owned apartment building serving common area electrical circuits only
Legend:
- Red Lines and Arrows
Depict the flow and direction of utility grid-supplied electric energy. - The Microgrid Interconnect Device
Performs several key functions related to the inclusion of battery storage in this solution:- Instantly detects the loss of utility grid power during a power outage.
- Engages and controls the use of battery discharge to supply backup power to essential electrical loads in the building during the outage (e.g., heating/cooling, refrigeration, lighting, Internet, water pumps, sump pumps, etc.).
- Detects utility grid power restoration and resumes normal operation.
- The Storage Batteries
Charged with utility grid energy and can be configured to discharge their stored energy during utility power failures and/or to supply nighttime time-shifted stored energy to the building. - The Common Area Electrical Panel
Supplied by two sources—both battery storage and utility grid—to help ensure that common area electrical circuits remain active at all times.
