Today, Upstart Power became Redde.

It’s pronounced “ready,” a name that describes exactly what our product does. It keeps your property powered, without anyone having to think about it.

More homes and businesses have batteries and solar than ever, and for good reason. But every battery has a limit. When the grid goes down for an afternoon, that’s rarely a problem. When it goes down for days, most battery systems run out before the grid is restored.

For years the only answer was an internal combustion standby generator. Those work. But they also bring noise, engine exhaust, weekly test cycles, and an annual service call.

That’s the gap our product closes. Redde watches your battery and recharges it automatically, running on the natural gas or propane already at your property. No noise, no engine exhaust, no routine maintenance.

And your fuel goes much further. A 250-gallon propane tank can last 50 days or longer with Redde. Compare that to just about 6 days for a traditional standby generator.

We make a three-day outage, or a three-week one, look no different than a three-hour one.

You can tell we’re excited today. Our technology hasn’t changed. Only our name has, and it’s the one we’ve been living up to since the beginning.

The long-duration backup power industry hasn’t changed in decades. It’s about to.

Redde. Always ready.


The name has roots in two languages that don’t usually meet. Latin reddere, to give back or restore. Norwegian redde, to rescue.
Different origins. The same idea: power that’s there when you need it.
