Store the solar you make by day. Run your home — and your car — after dark.
Voltura Energy designs, supplies and installs battery storage and EV charging systems for homes and businesses, with backup power that kicks in automatically when the grid drops.
Three reasons Voltura customers make the switch
Use your solar after sunset
Store excess daytime solar and draw on it in the evening instead of buying it back from the grid at peak rates.
Blackout backup
Essential circuits switch over automatically within milliseconds when the grid goes down — no generator required.
Modular & scalable
Start with one battery and stack additional units later as your household or business energy needs grow.

Common questions
No — batteries can be charged from off-peak grid power too, though pairing with solar gives the fastest payback.
Eligibility varies by state and changes periodically. We check current federal and state battery rebates during your free assessment and apply them to your fixed-price quote.
Yes — most customers combine both in a single install to make the most of one electrician visit and one switchboard upgrade, if needed.
