Customer Story

“When the grid went down for four days, the sonnenBatterie eco 10 system in combination with my 10kw solar system kept my power running and helped us comfortably weather Hurricane Hermine.”

While Florida is no stranger to tropical storms, Hurricane Hermine—the first hurricane to make landfall in Florida in over a decade— was particularly brutal, generating 80 mph winds and almost 2 feet of rainfall.  Hermine wreaked devastating havoc across the state, leaving 325,000 people and in some cities 80% of the city proper without power. Jim McBrayer, a northern Florida resident who has dealt with his fair share of power loss due to storms, knew Hermine was coming and wanted a clean solution to protect his household and his livestock.

By combining a 10 kW PV system with two eco10 sonnenBatterie smart energy storage systems and a generator, Jim McBrayer generates and stores enough clean energy to power his home and keep the lights on, even at night during outages. By adding a battery storage system to his house, Jim’s PV system will continue working during the day even when the grid goes down – without it the PV system would shut off during an outage.

Even with one sonnen unit out of commission, Jim was able to use his secondary unit in conjunction with his solar system to provide all the power he needed during the storm. “The timing of installing the sonnen eco 10 systems before Hermine hit could not have been more perfect. The batteries kept our PV system running during the day providing critical power for water for our home and livestock, and keeping our refrigerator, our AC and our lights on. We also had enough energy for FULL home power throughout the night. I probably saved $1,000 on food and was the only one on my block with power – thanks to the sonnenBatterie.”
