Overview
Why add a home battery wall pack?
AJ Long Electric supplies and installs listed home battery equipment, or connects customer-selected listed batteries, so selected household circuits stay powered during an outage. The defined scope may include a wall-mounted power station, a backed-up-load panel or smart home panel, transfer equipment, conductors, protection, labeling, and commissioning. We start with the circuits you want to keep alive, the equipment ratings, the existing panel, and the route. Portable generator hookups stay on the generators page. Tesla Powerwall and Enphase whole-home product sales are quoted only when the listed equipment and interconnection path are confirmed for the property.
Selected-Load Backup
The design starts with the circuits that matter during an outage, not a one-size whole-house package.
Listed Equipment
We supply EcoFlow, Bluetti, and Anker SOLIX systems, or connect other listed customer-selected batteries.
Panel Integration
Transfer equipment or a smart home panel keeps utility and battery sources from backfeeding each other.
Silent Indoor Operation
Battery systems produce no exhaust, so they can sit in a garage or utility space without a fuel-burning generator.
Solar-Ready Path
Grid and, where the equipment allows, solar recharge are documented in the written scope.
Signs You Need This
You want silent backup for refrigerator, internet, lights, and medical equipment
A portable generator is not practical for your lot or HOA
You are adding an EV charger or panel upgrade and want backup planned at the same time
You already own a listed wall pack and need a code-compliant panel connection
Storm outages regularly last longer than a power station on an extension cord can cover

Northern Virginia Service Context
Serving the DMV Region
Fairfax, Arlington, Alexandria, Loudoun & Prince William Counties
Northern Virginia outages from summer storms and winter ice make silent indoor backup useful in attached garages, finished basements, and townhomes where a portable generator is hard to place. Panel location and HOA rules often decide whether a wall pack or a portable hookup is the better fit.

FAQs
Frequently Asked Questions
Get answers to common questions about our home battery & wall packs services.
What home batteries does AJ Long Electric install?
We supply and install listed EcoFlow, Bluetti, and Anker SOLIX wall-pack and power-station systems, and we connect other listed customer-selected batteries when the equipment, panel, and manufacturer instructions are compatible. Tesla Powerwall and Enphase product lines are evaluated per project.
How much does a home battery install cost?
$2,500-$6,000 portable; $6,000-$15,000+ whole-home, depending on capacity, whether the unit is portable or hardwired through a smart home panel, and the number of backed-up circuits. Equipment and electrical work are itemized on the written proposal.
Do you still install portable generator hookups?
Yes. Inlet boxes, manual transfer switches, and listed interlocks remain on the portable generator hookups page. This page is for battery wall packs and hardwired battery integration.
Will a battery work with a future solar array?
Many listed systems recharge from the grid and can accept solar input when the inverter and interconnection are designed for it. We document that electrical path. Rooftop solar installation is a separate, gated offer.
Does battery backup require a permit?
Hardwired transfer equipment and smart-panel connections typically need an electrical permit. We confirm the path for the address before work is scheduled.
