Power That Never Goes Out

What is it?

ensure is a central UPS (Uninterruptible Power Supply). In an outage, it uses battery power to keep things running — furnace, fridge, pumps, Wi-Fi, electronics and more.

And, ensure is so fast that your essential circuits never lose power — so your home or business stays powered, connected and protected…and you don’t need to worry about disruptions, damage, loss, or injury.

How it works

ensure continuously monitors your utility power for problems. Whenever there’s an outage or unstable power, it instantly switches to battery mode — so you don’t lose power for even a second.

When utility power is back to normal, ensure automatically recharges — ready for the next time you need it.

The correctly sized ensure model can provide backup power for up to several days. In a longer outage, auxiliary charging can be used to extend backup time — via solar panels, a portable generator, or an EV with a bidirectional charger. So with ensure, you’re prepared for even the longest outages.

ensure is clean, quiet, reliable, and built to last for more than 20 years — without having to replace the original batteries. That’s why we offer:

  • a 90-day money back guarantee
