Envy True 12kW
Uninterrupted Clean Power
Solar Storage Inverter for Residential and Commercial
The Fortress Power Envy True 12 kW is a whole-home, all-in-one 12kW inverter solution with a 21kW PV input (scalable up to 120kW AC output with 10 inverter units), compatible with any Fortress Power 48V battery.
Each Envy True 12kW inverter features a 200A AC passthrough, providing uninterrupted power for homes and businesses. It supports off-grid, grid-tied backup, net metering, time-of-use, zero export, and load-shifting applications, to name a few. The Envy True 12kW inverter allows you to choose between complete energy independence, selling excess energy back to the grid, or shifting your power consumption times to lower your electric bills significantly (even without solar panels), all while protecting you from power outages.
What’s more, the Envy True 12kW, along with eForce, eFlex Max, and eVault Max, is approved by numerous utilities across the U.S. and Canada, allowing you to receive generous payments from your electric utility companies for the energy your Fortress Power equipment discharges during peak demand periods.
