Don’t let the grid bring you down

ensure is a new battery backup system that keeps your home or business running during a power outage. It’s a central UPS (Uninterruptible Power Supply), featuring a simple yet robust design built on proven technology.

With ensure, you’ll always have stable WiFi and plenty of power for your furnace, fridge, lights, pumps, and other essentials. So when the grid’s down, you won’t have to worry about disruptions, damage, loss, or injury.

How it works

ensure stays fully charged as it monitors the flow of electricity from your utility provider. When an outage occurs, ensure instantly switches to battery mode — preventing any loss of power or connectivity.

Once normal service is restored, the system switches back to grid power and recharges the battery — ready for the next time it’s needed.

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.

Peace of mind

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

  • a 20-year comprehensive warranty
