Testimonials

“We are extremely happy with the decision to switch to SimpliPhi (PHI 3.5s) and love the reduction of footprint and weight, as well as the dramatically lengthened warranty and life expectancy.”
Ty T., Tiny House Owner Florida – August 2018

“We’ve been super impressed with how these work. These were a very easy install. They’re also completely scalable. That’s the neat thing about these SimpliPhi batteries – that as we grow with the project, as they add more things, which happens from the beginning of a project, it’s scalable – we just keep adding more batteries to this system.”
Jason Andrade of West Coast Sustainables, California – August 2018

“We like these batteries because of their relatively compact size and weight, safety, ability to charge and discharge at a high rate and their life expectancy.”
Scott Murakami, Hawaiian Outpost – November 2017

“(This system) provides the homeowner with a drastic reduction in their electric bill as well as the ability to live comfortably in any power outage situation.”
Appalachian Energy Solutions, North Carolina – November 2017
