We Install and Service Whole-Home Battery Backup Solutions

Power outages strike without warning. We install battery backup systems that keep your essential circuits running when the utility fails. Our electricians size the system based on your actual load calculations. We never use guesswork. We typically install automatic transfer switches rated between 100 and 200 amps. The rating depends on your panel capacity. Every installation meets NEC Article 706 requirements for energy storage systems. We work with lithium-ion and lithium iron phosphate battery technologies. Our team pulls all necessary electrical permits. We schedule inspections too. You get a system that starts automatically within seconds of an outage.

Proper Planning

Load Analysis and System Design

We calculate which circuits matter most to you during an outage. Our load analysis determines the battery capacity you actually need. We consider startup surge currents for refrigerators, well pumps, and HVAC equipment. You won’t pay for oversized equipment you don’t need.

Common Questions

Residential Electrical FAQs

Common questions from Triangle homeowners about residential electrical services. Don’t see yours? Call us directly — we’re happy to help.
How long will a battery backup system power my home?
Runtime depends on your battery capacity and what you’re powering. A typical 10 kWh system running essential loads like refrigerator, lights, and internet might last 8 to 12 hours. If you add heating or cooling equipment, expect 3 to 6 hours. We perform load calculations during the estimate. This gives you realistic runtime expectations for your specific needs.
Battery systems start instantly and run silently with zero emissions. Generators require fuel storage, produce exhaust, and take 10 to 30 seconds to start after an outage. Batteries need no maintenance like oil changes. However, generators can run indefinitely with fuel while batteries have fixed capacity. Many customers choose batteries for short outages and generators for extended ones.
Yes, most modern battery systems work with solar arrays. We install the proper charge controllers and set up the system to prioritize solar charging during daylight hours. This extends your backup runtime significantly during multi-day outages. The system can also reduce your electric bills. It stores solar energy for evening use when rates are higher.
Lithium-based systems require very little maintenance compared to generators. We recommend annual inspections. We check electrical connections, verify firmware updates, and test the transfer switch operation. The batteries themselves are sealed units with 10-year warranties typically. We monitor voltage levels and check for any fault codes during service visits to catch problems early.
We can design either whole-home or critical-load systems. Whole-home requires larger battery banks and higher-capacity inverters. Most homeowners choose critical-load backup. This covers refrigeration, some lighting, internet, medical equipment, and one heating or cooling zone. We install a sub-panel for backed-up circuits during installation. This approach gives you meaningful backup at a reasonable investment.

This approach gives you meaningful backup at a reasonable investment.
Transfer switch sizing depends on which loads you’re backing up. A critical-load system might use a 30 or 60-amp switch feeding a sub-panel. Whole-home backup typically requires a 100 or 200-amp transfer switch matching your main panel rating. We calculate the actual load to prevent nuisance tripping. This ensures the switch handles startup surges from motors and compressors properly.
