First sonnenBatterie eco 10 solar+storage system installed in California home

HelioPower, an integrated energy solutions company based in Murrieta, Calif., installed a sonnenBatterie eco 10 System in a Bonsall, Calif. home. In combination with an on-site solar array, the sonnenBatterie offers perpetual backup power in the event of a natural disaster or power outage, providing safety and peace of mind for homeowners.




sonnen’s energy management software, along with HelioPower’s integrated turnkey energy solutions and financing from the HERO Program, enabled the Marsh residence to complete its renewable energy initiative.
HERO is the nation’s largest residential PACE program and partners with local governments to make energy and water usage efficient, and renewable energy products more affordable for homeowners.

“I’ve always been a proponent of sustainable and innovative practices. The sonnenBatterie eco 10 was predominantly designed as a backup battery system for my first booster pump to my water reservoir; but, ultimately I chose to connect the eco 10 to a second booster pump for my fire sprinklers,” said Jay Marsh, the homeowner. “Since we have not yet experienced a wildfire, I haven’t tested out the system to its full capacity; although, it’s comforting to know that I have a backup plan. So far I am very pleased with sonnen’s stable, software interface and the unit’s power usage.”

The sonnenBatterie installation, along with a HelioPower photovoltaic system (PV) of LG 315 panels and SolarEdge 7600 optimizers/inverters, will power the homeowner’s second water pump motor. This pump connects his home to his personal water reservoir in the event of a wildfire or power outage, allowing water to continue to flow to his home.

HelioPower’s analytics and load profiling tools, as well as HelioPower’s distributed generation strategies work together to maximally reduce the homeowner’s total energy cost. HelioPower provided design, engineering, construction and utility commissioning for the battery and solar installation, delivering the project on schedule and within budget. The project was successfully commissioned in July 2016.

“We are pleased to add sonnen to our suite of energy cost reduction solutions for our residential customers,” said Mo Rousso, President and Founder, HelioPower, Inc. “HelioPower’s mission is to work with our clients to find the most cost-effective solution to all of their energy needs; be it solar power to produce their own electricity at wholesale prices; smart home energy products, such as high efficiency pool pumps, whole house fans, and smart thermostats to reduce energy consumption; or sonnen solar battery solutions to provide energy security during outages. This project demonstrates our capability to effectively solve complex design and installation challenges that other energy integrators find prohibitive, causing most of them to pass on pursuing the project.”

Have you checked out our YouTube page?

We have a ton video interviews and additional content on our YouTube page. Recently we debuted Power Forward! -- a collaboration with BayWa r.e. to discuss higher level industry topics as well as best practices / trends for running a solar business today.

Our longer running side project is The Pitch -- in which we have awkward discussions with solar manufacturers and suppliers about their new technology and ideas so that you don't have to. We've discusses everything from residential rail-less deck attaching and home solar financing to large-scale energy storage value stacking and utility-driven new home solar + storage microgrids.

We also post our Project of the Year announcements there! Interviews with this year's winners will be up starting the week of Nov. 8. Head there and subscribe today to stay on top of all this extra stuff.
