The Fortress Power Envy True 12kW is a high-performance, all-in-one hybrid inverter designed for whole-home and light commercial applications. With 21 kW of solar PV input, a 200A AC passthrough for whole-home backup, and scalable output up to 120 kW AC by paralleling 10 units, it delivers unmatched flexibility for grid-tied, off-grid, or backup systems. The Envy True 12kW is fully compatible with all Fortress Power 48V batteries, including the eForce, eVault MAX, and eFlex MAX. Whether you're looking to achieve energy independence, reduce peak utility rates, or participate in net metering and time-of-use programs, the Envy True 12kW offers advanced control and seamless integration.
Key Features & Benefits
12kW Continuous Output (True 12kW): Delivers 50A @ 240VAC (12,000W) with a 200A AC passthrough, providing robust power for whole-home backup and light commercial applications. Offers 10.4kW (50A @ 208V) for 208V systems.
Powerful PV Input (21 kW): Supports up to 21 kW of solar PV input (18 kW delivered to battery & AC outputs) across three independent MPPTs, maximizing energy harvest for on-grid and off-grid applications.
Three Independent MPPTs (25A/15A/15A): Features 2 strings on MPPT1 and 1 string each on MPPT2 and MPPT3, allowing flexible array configurations across multiple orientations for optimal energy harvest.
200A AC Passthrough for Whole Home Backup: Built-in 200A AC breaker enables whole-home backup without the need for a separate subpanel, simplifying installation and providing seamless power during outages.
Plug-and-Play Installation: Integrated AC and DC breakers (2x 200A battery breakers, 200A load breaker, and generator connection) and generous internal space for wire management streamline installation, reducing labor time and simplifying wiring for both retrofit and new systems.
Built-In Rapid Shutdown (RSD): Fully integrated APsmart rapid shutdown transmitter and button helps installations meet NEC 2017 & 2020 code requirements without external devices — saving time and cost.
Split-Phase & Three-Phase Support: Engineered for residential 120/240V split-phase systems and can also be used in commercial 120/208V or 127/220V three-phase setups with two or more inverters.
Parallel Capability (Up to 10 Units): Scale your system by paralleling up to 10 units for a maximum of 120kW of AC output, perfect for larger residential or light commercial installations.
AC & DC Coupling: Supports both AC and DC coupling, offering flexibility for various system configurations and existing solar installations.
Built-In Generator Input: Integrated generator input (100A max / 90A continuous) allows for backup power during extended outages, adding an extra layer of system reliability.
Virtual Power Plant (VPP) Ready: VPP-compatible and approved by utilities across the U.S. and Canada, allowing you to participate in demand response programs.
Battery-Agnostic Design: Seamlessly integrates with a wide range of lithium batteries, including Fortress Power's eForce, eVault MAX, eFlex MAX, as well as other major lithium battery brands (open-loop) and lead-acid.
Remote Monitoring & Firmware Updates: Monitor solar production, battery performance, and grid consumption anytime via the Fortress Power mobile app (Guardian). The Envy also supports remote firmware updates, ensuring your system stays current.
NEMA 4X / IP65 Rated: Suitable for indoor and outdoor installations with robust environmental protection.
10-Year Warranty: Backed by a 10-year limited warranty.
