Fortress Power FlexTower Inverter Enclosure
The Fortress Power FlexTower is an all-in-one enclosure solution that transforms your solar equipment into a sleek, unified appliance. By combining the DuraRack battery cabinet (bottom) with the FlexTower Inverter Cabinet (top), it creates a single, IP65-rated tower that houses both your batteries and inverter. Designed to hold up to four eFlex batteries and a Fortress Envy inverter, it eliminates unsightly conduit and simplifies installation for a clean, professional finish indoors or out.
Why Choose Fortress FlexTower
The FlexTower is the aesthetic choice for homeowners who don’t want a “science experiment” on their wall. It takes the industrial look of separate inverters, battery racks, and conduit runs and hides them inside a modern, weather-resistant cabinet. Beyond looks, it drastically speeds up installation because it comes pre-wired with battery combiners and busbars, allowing installers to simply slide the batteries in and bolt the inverter on.
