Battery Backup and Critical Load Panel Installation in Northern Virginia
Backup power without the noise, the fumes, or the gas can. A battery and a critical load panel keep the circuits you cannot do without running automatically when the grid drops, across Fairfax, Loudoun, Arlington, and Prince William.
You lose power more than once a year Something in the house cannot just stop: a sump pump, a freezer, medical kit You would rather not store fuel or run a machine outside at 2am
What a Critical Load Panel Actually Is
It is the first question in the FAQ at the bottom of this page and it has never been drawn. A critical load panel is a subpanel holding only the circuits you decided matter. Here is the same house in both states.
What most people put on it
Refrigerator and freezer
Sump pump
Internet and router
Lights on the main floor
Furnace or air handler controls
Medical equipment
Garage door opener
A few key outlets
The list is the whole design decision. Every circuit you add shortens how long the battery lasts, and every one you leave off is something you will notice at hour six of an outage. We work through it with you before anything is sized, because getting it wrong in either direction is expensive.
If You Do Have a Generator, Please Read This Part
We would rather sell you a battery. We would much rather you did not die of carbon monoxide poisoning in the meantime, so here is the actual rule rather than a vague line about fumes.
~100
people a year die in the United States from carbon monoxide poisoning caused by portable generators, on CPSC's figures.
Never indoors
Not in a house, garage, basement, crawlspace or shed, and not on a porch or in a carport. Opening the door does not make it safe.
20 feet
Outside only, at least twenty feet from the house, with the exhaust pointed away from every door, window and vent.
Guidance and figures from the U.S. Consumer Product Safety Commission. Read the CPSC page on generators and carbon monoxide. If you use a generator, CPSC also asks for working carbon monoxide alarms with battery backup outside every sleeping area, and newer models are available with an automatic carbon monoxide shutoff. A battery sidesteps all of this, which is the honest reason we prefer them.
Why Battery Backup Wins
It switches over on its own
No going outside in the rain, no pull cord, no extension leads through a window. The transfer happens automatically when the grid drops, fast enough that most things in the house never notice.
Nothing to hear and nothing to smell
No engine, no exhaust, and no fuel to store or fetch. That is also why it can live in a basement or a garage, which a generator cannot.
Nothing to fuel, no oil, no monthly test run
A generator needs oil changes, filters, fresh fuel and a regular run to be there when you need it. A battery does not. It still wants an eye kept on it, and it will lose capacity over its life, but there is no chore list.
Solar ready, whether or not you have solar yet
Most modern systems can take panels later, which turns an outage battery into something that also recharges itself when the sun is out.
Sized now, expandable later
Start with the circuits you cannot do without and add capacity as budget allows, rather than buying for a worst case on day one.
Installed Right, by Master Electricians
Sized around your house, not a catalogue
We work out what your essentials actually draw before anybody picks a battery, which is what decides whether the thing carries you through the night or for two hours. If your service is older or showing strain we will say so, and our guide to the signs your electrical system is failing is a good place to start.
Permits pulled and inspection booked
Battery and subpanel work is permitted work. We file it and schedule the inspection, so the install leaves a record behind it.

A price agreed before the work
The scope, the options, and what each one involves, explained before anything is agreed.
Financing on a system this size is available on request, and the veteran discount program applies.

What Your Neighbors Are Saying
Top Questions and Answers
What is a critical load panel?
It is a subpanel that isolates your essential home circuits, so your backup battery powers only what matters most during an outage.
Can a battery backup system run my whole home?
Most homeowners power only the essentials, but yes, systems can be expanded with added capacity to cover your full home.
How long will a battery backup last during an outage?
That depends on your usage and capacity. Most setups run critical circuits for several hours up to a full day.
Do battery systems require maintenance?
No. They are virtually maintenance free, with no oil changes, gas, or tune-ups needed.
Are these systems safe indoors?
Yes. They produce no fumes or exhaust, which makes them safe for basements, garages, or utility rooms.
Do you handle permits and inspections?
Yes. We take care of everything, from pulling the permit to passing the final electrical inspection.
Can I add solar to my battery system later?
Yes. Most modern systems are solar ready and easily expandable down the road.
What happens when the battery runs out?
It automatically shuts off until the grid returns or it recharges through solar.
Is the transfer automatic during an outage?
Yes. The switch happens instantly, often in less than a second.
Can this system work with an EV charger?
Yes. We can integrate EV charging into your backup setup for complete energy management.
