Home Battery Backup in Richmond

Because a grid-tied inverter is required to disconnect when it loses the utility, so that it is not energising lines that crews believe are dead. That is anti-islanding, it is a safety requirement rather than a product limitation, and it applies to every grid-tied array in the city. Dominion's own net metering page states the consequence plainly: supplying your home during an outage requires an energy storage system and a transfer switch. Adding a battery and the right switching is what changes the behaviour.

Dominion's net metering terms require the system to be sized so that it does not reasonably produce more energy than 150% of expected annual electrical consumption. That is a consumption-based limit and it is frequently reported as a fixed kilowatt cap instead, which is a different rule with different consequences. The practical effect is that the ceiling is derived from your own usage history rather than from a number that applies to every house, so the sizing conversation starts with your bills. Dominion separately notes that batteries may be part of a renewable generation system but are not a renewable generation source on their own.

Four steps. A Net Metering Interconnection Notification submitted online, by email or by mail. A contingent approval after a compatibility review, which both you and the vendor sign. Certification by a licensed Virginia electrician, or approval by the local inspection authority. And finally permission to operate, issued once metering and billing work is complete. Nothing runs in parallel with the grid before that last step, and it is the same gate that governs solar — which is exactly where projects sit idle when the paperwork was treated as an afterthought rather than as part of the schedule.

That depends on the circuits you connect and on whether solar is recharging the battery, and it cannot be answered from a postcode. A battery holds a finite amount of energy that is drawn down by whatever is on the critical load panel. Connect a whole-house air conditioner or electric heat and the answer is short; connect refrigeration, lights, networking, heating controls and a sump pump and it is much longer. We size to a list of circuits you choose and we do not publish a runtime figure.

The residential code permits a defined set of locations for stationary battery storage and excludes others outright, habitable rooms and sleeping rooms among them. Attached garages, detached garages, outdoors on an exterior wall and in a dedicated utility space are the usual candidates, each with its own conditions. Older Richmond housing stock adds practical constraints that the code does not: a basement that floods, a garage that is really a workshop, and exterior walls facing a narrow side yard. The siting checker on this site walks the code side in a few minutes.

They fail differently. A generator needs stored or delivered fuel and mechanical service it rarely receives, and it does nothing the rest of the year. A battery is silent, starts instantly, needs no fuel and can do other work between outages, but it holds a finite amount of energy unless something recharges it. For the scattered multi-hour outages an ice storm produces, a battery is usually the better fit. For a week without power, the pairing that wins is solar plus storage rather than either device alone.

Seamless Home is the licensed contractor of record on the work it runs. Installation is performed by vetted installing partners engaged as our subcontractors, so the permit, the inspection and any correction notice carry one name rather than being handed between parties. Coverage is confirmed per service area rather than promised as blanket availability.
