The Concord project opted to go with Solar (PV) connected to an energy storage system (battery storage) in lieu of a backup generator.
This system has been designed to keep the critical loads for the home operational even if the utility power is knocked out.
This system has been designed to keep the critical loads for the home operational even if the utility power is knocked out.
This includes the backup heating and domestic hot water system (gas boiler with radiant floor heat + indirect hot water tank), the refrigerator, freezer, microwave, TV/WiFi, lighting and receptacles in strategic areas.
The Generac PwrCell provides 18 kWh of battery storage in a single cabinet, and up to 9 kW of continuous power output, enough to power the critical loads for extended periods of time. It can also be expanded to 36 kWh of battery storage in the future should it ever be needed.
The solar+battery solution made sense on this project due to the client’s expectations/goals, ability to match up with gas heating and hot water (for lower electrical loads), and energy efficient appliances/lighting.
The house is also future proofed if the utility switches to Time of Use rates for electrical billing, as the battery can operate during times of peak charges (instead of using grid power).
