sonnenBatterie eco User Reviews

  1. I’ve definitely increased my monthly savings with the sonnen battery eco. While it’s of course not enough storage space to allow anyone to go off the grid, it’s capable of storing several hours worth of excess solar electricity, rather than sending that back to the grid. If you have already invested in a solar panel system, it only makes sense to improve your storage and make the most of the electricity you’re harvesting. Though it’s expensive to install, I would recommend the investment.
