6 reviews for eVault 18.5kWh LFP Battery

  1. Ray Warner

    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.

  2. Elmer Ebersol

    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.

  3. Pieter Huebner

    Fantastic Company and a great product, the support has been great and the staff at Fortress always welcomes input form the field

  4. Collin McDougall

    Absolutely incredible! Everyone who I spoke with was on point, professional, and well versed. I will be recommending Fortress Power to everyone I know. Truly incredible!

  5. Roman Hryhochuk

    well spoken people and very helpful. had a great experience and recommended for anybody looking for battery back up

  6. Ruth A Reed

    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.
