Northern Virginia outages are usually hours, not weeks. The wall pack should keep food cold, the network up, and medical devices running. It should not try to start a four-ton heat pump unless the system was sized for that on purpose.
Key Takeaways
- Priority circuits: fridge, communications, selected lights, medical, sump/well.
- High-draw HVAC and two EV chargers usually stay off the backed-up group unless the system is whole-home class.
- Portable generator hookups remain a separate path at $900–$2,500.
How we build the list on site
We walk the directory, measure or estimate running watts, and match that to the listed continuous and surge ratings of the battery. The written scope names the circuits. It does not say “whole house” unless the equipment actually can.
Planning Backup Power for Your Home?
Stay powered through the next outage. We install portable generator hookups — manual transfer switches, interlock kits, and exterior inlet boxes for safe, backfeed-free connection — and we supply and install battery backup power stations (EcoFlow, Bluetti, Anker SOLIX) for silent, fuel-free runtime.
