Benefits of Inverters From Fortress Power
Whether you’re building an expansive commercial energy system or trying to take your home off the grid, you can’t go wrong with a Fortress Power inverter. The Envy series ranges from 8kW, 10kW, 12kW, and 21kW with the Envy Duo. The eSpire Nano platform takes over from there at 30kW and 60kW for three-phase commercial systems.
Every Envy model is a true hybrid inverter with built-in MPPT charge controllers, automatic transfer switches, and battery management all inside one unit. You’ll wire your solar panels, battery bank, grid connection, and, if needed, a generator, into a single box. The Envy 8 and 10 run dual MPPT; the Envy 12 and Duo 21 have triple MPPT for bigger PV arrays.
Customers love how the Envy supports up to 10 units in parallel, too, so you can start with just one 8kW unit and expand as your load grows over the years. The eSpire Nano parallels up to 6 units for bigger commercial settings.
The whole lineup is backed by a 10-year warranty and features NEMA 4X enclosures for indoor and outdoor mounting alike. Your Fortress Power inverter comes equipped with a color touchscreen and WiFi for monitoring without extra hardware. Order today and find out firsthand what separates Fortress from the rest.
