Make It. Store It. Live On It — How VoltSol's Battery System Works
A solar + battery system built to make your utility bill optional — heating, cooling, and everything else, powered by what you make and store, not what they sell you.
Make it. Store it. Live on it.™
Same sun. Shorter path.
Why ordinary solar still leaves you tied to the utility — and how we cut the cord.
Ordinary solar
Panels → inverter → grid → meter → back to your house → AC
- Every conversion loses energy along the way
- You're still buying power back from the utility
- Rates and rules can change on you anytime
- When the grid goes down, your AC goes down with it
The VoltSol way
Panels → straight into your AC. That’s it.
- Solar plugs directly into the system — no round trip
- 100% daytime energy savings on sunny days
- A battery banks the extra for night and outages
- Keeps your home comfortable even in a blackout
How it actually works
MAKE IT
Rooftop panels turn free sunlight into power and feed it straight into the system — no inverter middleman skimming energy off the top.
STORE IT
A home battery banks the extra power for nighttime and blackouts, so the sun you caught at noon still cools your house at midnight.
LIVE ON IT
Whole-home heating and cooling runs on stored sun — comfortable, quiet, and on sunny days, powered entirely by the panels on your roof.
100%
daytime energy savings on sunny days
When the sun's out, your heating and cooling can run on $0 of utility power. That's the difference between renting electricity and making your own — and it's why so many homeowners watch their bill fall toward zero.
Built to handle all four seasons
Real performance, in plain English.
Cools a whole home, sips power
Up to 36,000 BTU across as many as 4 rooms — about 2,000 sq ft — at an efficiency rating (SEER2 up to 22.5) that puts it among the most efficient systems made.
Handles a heat wave and a cold snap
Keeps cooling in triple-digit heat and keeps heating when it drops near freezing — true four-season comfort.
Whisper quiet indoors
As low as 29 dB on the indoor units — quieter than a library reading room. You'll forget it's running.
Cleaner refrigerant
Uses modern R32 refrigerant — more efficient and lower environmental impact than the older blends in most legacy AC systems.
Smart install, lower cost
Quick-connect, pre-charged lines mean a faster, cleaner installation — less labor on the bill, no torch-and-vacuum guesswork.
Backed for the long haul
Covered by a manufacturer limited warranty, installed by a licensed local pro who stands behind the work.
Right-sized for your home
One outdoor unit can run two to four indoor zones. We match each room to the right size — so you never overpay for capacity you won't use.
