How it works

Battery takes over instantly

The moment the grid fails, your battery handles the transition. No gap, no flicker. Redde sits idle — it doesn't run unless it needs to.

Redde stabilizes the battery

When the battery dips below a set threshold, Redde quietly cycles on, recharges it, and shuts back down.

“The importance of having fuel cells as backup to the battery is that they keep you powered in the event of a loss of power or during the winter months when you don’t have as much sun to help keep up with your demand.”
