World Class Battery Storage
Renova Energy Corp. has been partnered with Sonnen Inc. for over 3.5 years and installed many of their residential advanced energy storage units for our solar customers in the Palm Springs/Palm Desert Area. In 2017, we built a 100% off-grid solar + battery system in the remote desert area of Landers, CA using Sonnen's ECO-16 lithium-ion battery system. The customer is enjoying an on-grid lifestyle with no connection to the local utility.<br />Renova Energy enjoys the partnership and great support that Sonnen provides to our customers!

Love this Product! ! !
These Sonnen Batteries are wonderful product. They are an AC coupled system and can currently store up to 16kWh. As with most back-up battery you need a dedicated sub-panel but they integrate easily if you know what you are doing and they have sleek looking cabinet. Sonnen answers their phones and we have found the Sonnen salespeople and engineering to be knowledgeable and helpful.
