With battery
Grid only
Grid-only electricity follows rising, variable tariffs. A battery lets you buy most of your energy at off-peak rates, cutting your long-term spend.

Frequently asked questions
Do I need solar panels to have a battery?
No. Your battery charges from the grid overnight at low-cost off-peak rates, then powers your home during the day when rates are higher. For larger homes, we can design a complete system that pairs solar panels with your battery.
Can a battery run my pool heating?
Yes. We pair battery storage with an efficient heat pump, so most of your pool heating runs on energy bought at off-peak rates.
Can I charge my electric car from the battery?
Yes. SigenStor can include an EV DC charging module, so you can charge your car from energy stored at off-peak rates.
