Both run on fuel. But, unlike a generator, Redde converts the fuel directly into electricity through an electrochemical reaction — quietly, efficiently, with no combustion and no moving parts to wear out. Redde cycles on only when your battery needs a top-off — then shuts back off. That difference in efficiency and runtime is what makes a 250-gallon tank last more than 50 days.

"We live close enough to our neighbors that a generator was never really an option. This runs so quietly, most of them don't know we have backup power at all."

“I love my Redde fuel cell generators. They run off of the propane that I already have delivered to my house, and they only use a tiny amount of fuel to keep my battery system charged when the solar panels aren’t producing enough electricity."

"It's extremely low maintenance, and the efficiency is impressive. Depending on the season, it handles my whole home's power needs."

" It uses a tiny amount of natural gas and automatically tops up our batteries so we can keep our whole home running no matter the weather or wildfire situation. We recommend this generator to all of our neighbors!"

Commercial buildings and businesses
Generator noise isn't an option in customer-facing spaces. Redde keeps critical loads running without the noise, the exhaust, or the maintenance.
