About ESPi

Since ESPi began in 2009, our mission has been straightforward: to build the best battery and solar UPS solutions on the planet.
Our entire corporate foundation is built on input from industry leaders like you. Your complaints and comments of the challenge to keep networks up and running were the reasons for the innovation and engineering in our first-in-class battery backup UPS product lines of NEO Indoor, TITAN Outdoor, TITAN Solar and TITAN Duplex.

Your feedback continues to help us innovate. Today, ESPi leads the powering industry, not just the battery backup segment. VOLTAR, our off-grid solution came about from customer requests that weren’t being solved. Whether it is used on wireless towers in the middle of Montana, an oilfield in West Texas or on the farm, VOLTAR brings power where it is needed.

At ESPi, we design solutions. For the telecom industry, there is no other solar system for ONT solution than VOLTAR. We lead with battery backup solutions using innovative battery technology others can’t match.

Because we listen to you, we’re able to lead and deliver the best battery and solar UPS solutions on the planet.
