What you get
A system sized to your house
How much you need depends on what you want running and for how long. I work that out with you at the quote.
Installed start to finish by me
One person from the quote to the final test. No crew, no subcontractors, and nobody learning on your house.
Permit and inspection handled
I file the paperwork, pay the fee, and coordinate the inspection.
What the system is actually made of
People say “battery” like it is one box. It is usually four or five parts. Knowing what each does makes the quote easier to read.
- The battery. Where the power sits. Measured in kilowatt-hours, which means “how much.” Many systems let you add more later.
- The inverter. Turns the battery's power into the kind your house uses. Some systems build it in. Others put a separate box on the wall.
- The transfer switch, or gateway. Watches the grid and moves you to the battery when it drops. This part makes it automatic instead of something you walk outside and flip.
- A backup panel. Backing up part of the house? The circuits you pick move into their own small panel.
- Monitoring. Sensors on your main feed and an app. You see what is charging, what is draining, and how long you have left.
Where it goes matters too. Batteries have a temperature range they work best in. An unheated garage through a Colorado winter is worth talking about before anything gets mounted.
Whole house, or just what matters
Backing up every circuit takes a bigger system than most people expect. Backing up what you care about costs less and runs longer on the same battery. Fridge, furnace, internet, a few outlets, the well pump.
Neither answer fits everybody. It comes down to what you want running at two in the morning in February, and what you want to spend. You get both laid out with a real number on each.
Which brands I install
I am not certified for the Tesla Powerwall, so I do not install those. Better you hear it now than after I take the job.
Brands I install include EcoFlow, EG4 and FranklinWH. Some makers only let installers they trained touch their equipment, and that list moves. Have a brand in mind? Bring it up when I come out and I tell you straight.
I sell no battery brand, so I have no reason to push one.
Battery or generator?
A battery runs silent and switches over on its own. No fuel to store or keep fresh. It runs until empty, then needs sun or grid power to fill back up.
A generator keeps going as long as you feed it. It is louder, it needs fuel and maintenance, and many need you to go start them.
People land on one or the other for good reasons. Some end up with both. The generator page covers that side. I price both so you compare real numbers.
Common questions
How long will it run my house?
It depends on the size of the battery and what you leave on. A fridge, some lights and internet draw far less than an air conditioner and an electric dryer. At the quote I go through what you want covered and give you a real estimate, not a brochure number.
Do I need solar for it to be worth it?
No. A battery charges from the grid, so it works as backup on its own. Solar changes the math on refilling during a long outage. Most systems take solar later if you want it.
Can I add more battery later?
Often yes, and it is worth asking before you buy. Systems differ on how far they expand and whether the extra has to match. I check that for the system you are considering.
Will it work with my panel?
One of the first things I look at. Some installs tie in cleanly. Others need panel work first. If yours needs an upgrade you hear it at the quote, not partway through. See panel upgrades.
Do I need a permit?
That's up to your town and I check for your address. Where one is needed I pull it, pay the fee, and coordinate the inspection.
Is it noisy?
No engine, so nothing like a generator. Most have cooling fans you might hear up close. The neighbors will not.
How much does it cost?
It moves a lot with the size of the system and how much of the house you back up. A number over the phone would be a guess. I come out, look at your panel and where the equipment goes, and hand you a flat written price.
Why most people dread hiring an electrician
Everyone has a story about a contractor. Here's what usually goes wrong, and what I do instead.
They charge by the hour, so you never know the final price.
The price I quote is the price you pay.
They show up late (or not at all).
I show up on time (or $100 off).
They vanish when something fails.
The work is right, for life.
They sell you as much as they can, even if you don't need it.
I tell you what you don't need, in writing.
I take pride in doing it right, the first time.
