Residential Microgrid
Systems in South Carolina.

A residential microgrid is a locally controlled energy system that integrates solar generation, battery storage, backup generators, and intelligent controls into one coordinated private power infrastructure. Unlike a single generator or battery product, a microgrid manages multiple energy sources automatically to power an entire property — whether the utility grid is available or not.

A residential microgrid may be designed for selected critical loads or larger whole-property loads. Coverage depends on the property's load profile, battery capacity, inverter output, generation resources, controls, and operating priorities.

Runtime depends on load, storage capacity, available generation, fuel supply, equipment ratings, maintenance, and operating conditions. Compatible generator backing may extend operation when the system is designed and configured for it.

A generator can be one resource within a larger coordinated microgrid. Depending on the equipment and design, storage and controls may reduce startup interruption, coordinate generator operation, and reduce fuel use compared with generator-only operation.

No. While solar generation is a common and valuable component, a residential microgrid can be built with battery storage and generator integration alone. Solar reduces generator runtime and fuel costs during extended outages, but the system operates with or without it depending on property needs and design goals.

Every residential microgrid is scoped as a property-specific engineering project. Investment depends on battery capacity, generation sources, home loads, existing electrical infrastructure, site complexity, utility requirements, and operating goals.

Prime Microgrid serves properties throughout the 48 contiguous United States. Alaska and Hawaii are not currently served. Contact us to discuss your property and energy goals.

Battery backup can support selected loads or broader coverage depending on its design. A microgrid is the larger coordinated architecture that may integrate storage with onsite generation, backup generation, controls, protection, loads, and the utility-grid interface.

Modern microgrid controllers may support software-assisted load management, battery optimization, generation forecasting, storm preparation, and generator coordination, depending on the controller platform and system configuration.

Residential microgrids are best suited for large primary residences (4,000+ sq ft), estate properties, coastal homes, rural properties with long grid restoration times, vacation homes that need unattended protection, and any property where power disruption would cause significant financial or safety consequences.
