I like to Fortress Evault. Nice battery. We have installed 2 of them. I just wish they wern’t so darn heavy! Difficult to load/unload.

Great people to work with and great products….This company is always open to ideas and feedback, as a Solar installer who deals with many different manufacturers they are one of my favorites.

We have been using the Fortress eVault for almost a year. We love the battery. For off grid living I don’t believe you can beat it. I wish Fortress made a remote monitoring screen that we could mount in the house so we don’t have to venture out to the battery house to check on it on cold dark rainy nights.
