We been installing Fortress Power batteries for a couple years in San Diego California and they are a very nice Lithium Iron Phosphate (LiFePO
4) battery solution. Save time on the cost of labor. Roll it up to the wall and run your conductors. No need to hang two or three 270 pound batteries on your wall. Unlike other popular batteries, it has a nice charge and discharge rate to handle the high demand. If you are concerned about support they are there to help you through the details. Our clients like the nice simple look and it takes very little room in the garage. It is a nice clean solution!
