Whole Home Backup Power
Complete Residential Power Protection That Keeps Every Circuit Running
Most backup systems protect a handful of critical circuits — your refrigerator, a few lights, maybe a phone charger. That is not whole-home backup. Whole home backup power means your heating system, water heater, well pump, kitchen appliances, HVAC, and every other circuit in your house stays fully operational the moment the grid goes down — exactly as if nothing happened. No load shedding, no manually switching between protected and unprotected circuits, no compromises.
BiG Energy engineers and installs whole house backup power systems for residential properties across Connecticut, New York, Massachusetts, and New Jersey. We assess your home’s complete electrical load, size battery capacity around your full panel draw, and configure automatic transfer systems that engage in milliseconds — delivering genuine, total-home power protection that performs without any input from you.
Benefits Of Whole Home Backup Power
- True Full-Panel Coverage: Every circuit in your home stays live during grid outages — not just the ones you remembered to prioritize.
- Instant Automatic Transfer: Your whole home battery system switches from grid to stored power in milliseconds, faster than a single light flicker.
- Northeast Winter Ready: Maintain your heating system, hot water, and sump pump through multi-day ice storm and blizzard outage events.
- No Manual Operation Required: The system monitors grid status continuously and engages without any action from you or your family.
- Solar Integration: Pair your whole-home battery with rooftop solar to recharge during extended outages and reduce daily grid dependence.
- Scalable Battery Capacity: Add battery modules to extend your whole-home runtime as your household’s energy needs grow.
- Long-Term Manufacturer Warranties: Premium whole-home battery platforms carry 10-year warranties with guaranteed minimum capacity retention.
- Whole Home Backup Power Applications
Full-Property Power Protection for Every Home Type and Outage Scenario
Large Single-Family Homes
Larger homes with multiple HVAC zones, electric water heaters, and high ambient loads require oversized battery capacity to maintain whole-home coverage through extended outages. BiG Energy sizes whole home backup power systems specifically around your verified panel load data — not generic estimates.
Homes With Electric Heating Systems
Properties running heat pumps, electric furnaces, or electric baseboard heating face their greatest outage risk in winter. A whole house battery backup system sized for your heating load keeps your home warm and functional through the Northeast's most dangerous storm outages.
Well-Dependent Rural Properties
Rural homes relying on electric well pumps for water supply need backup systems capable of handling motor startup currents and sustained pump draw. Our whole home battery system configurations account for well pump loads within the full-panel backup specification.
Homes With Medical Equipment
Households with family members dependent on electrically powered medical devices — oxygen concentrators, CPAP machines, infusion pumps — require uninterrupted power across all circuits, not just selected ones. Total-home backup eliminates the risk of accidentally losing power to any critical device.
Multi-Level & Custom-Built Properties
Custom homes with complex electrical configurations, smart home systems, EV chargers, and distributed HVAC equipment require detailed load analysis before selecting backup hardware. BiG Energy engineers whole house backup power systems that account for every load in your specific property.
Solar + Whole-Home Storage Systems
Combining whole-home battery backup with a rooftop solar array creates a self-sustaining residential energy platform. During extended outages, your solar panels continuously recharge your battery — providing indefinite backup capability as long as sunlight is available.
