Off-Grid Home
Power Systems.
Private power systems for remote estates, rural properties, and homes where a utility connection is unavailable or unsuitable. Off-grid feasibility depends on load analysis, seasonal generation, storage, backup resources, maintenance, and site conditions. See how this differs from a grid-connected home microgrid.

Depend on the Grid.
Off-grid residential power systems are designed for properties where utility power is unavailable, unreliable, or simply unacceptable as a dependency.
Off-Grid System Architecture
A properly engineered off-grid residential system is built with N+1 redundancy — meaning there's always a backup for the backup. Solar, battery, and generator work as a hierarchy: solar is primary, battery is the buffer, generator is the last resort. Satellite monitoring keeps the system managed from anywhere.
Primary generation source. Oversized for seasonal variability.
24–72+ hours of capacity. Handles nights and low-solar days.
Automatic activation for extended low-generation periods.
Remote visibility and control from anywhere in the world.
Frequently Asked Questions
What is a residential off-grid power system?
A residential off-grid power system supplies electricity to a home entirely from on-site sources — solar, battery storage, and/or generator — with no connection to the utility grid. It requires careful engineering to size generation, storage, and backup capacity for year-round, all-weather operation.
Can a large luxury home operate fully off-grid?
Yes — with the right engineering. Large homes require correspondingly larger solar arrays, battery banks, and backup generation. Prime Microgrid specializes in off-grid systems for high-load residential properties, including homes with HVAC, EV charging, pools, and other high-consumption loads.
What's the difference between off-grid and grid-tied with backup?
A grid-tied system with backup remains connected to the utility and uses stored energy during outages. A true off-grid system operates independently with no utility connection — typically by necessity (remote location) or by design (full energy independence). Both require rigorous engineering; off-grid systems require more redundancy.
How is an off-grid system monitored if the property is remote?
We configure all systems with satellite-capable remote monitoring, allowing real-time visibility into generation, storage, and consumption data from anywhere in the world. Alerts are configured for fault conditions so the system can be managed proactively even from a distance.
What fuels work with an off-grid generator?
Off-grid systems can integrate propane, natural gas (where available), diesel, or dual-fuel generators. Propane is commonly used for remote properties due to on-site storage capacity. The generator is the last resort in the generation hierarchy — batteries and solar run first; the generator activates only when needed.
Everything Stays On.
Customer-sited generation + energy storage + backup generation + intelligent controls = whole-property power continuity.
