8K ENVY Whole Home Storage Inverter

8K ENVY Whole Home Storage Inverter

The Fortress Power Envy 8/10kW Hybrid Inverter is an all-in-one solution built for whole-home energy storage and backup. It pairs seamlessly with the eFlex 5.4 kWh, eFlex MAX 5.4 kWh, eVault MAX 18.5 kWh, or LFP-10 MAX batteries and delivers up to 8kW (33.3A @ 240V) or 10kW (41.6A @ 240V) of continuous output through a 60A AC passthrough. With AC and DC coupling, a built-in generator input, and dual MPPTs, the Envy supports up to 13 kW of solar PV input (for 8kW mode) or 15 kW (for 10kW mode), making it ideal for both on-grid and off-grid applications.

Designed for fast, code-compliant installation, the Envy includes integrated AC and DC breakers and a built-in APsmart Module Level Rapid Shutdown Transmitter and Button. System owners and installers can take full control with the Fortress Power Guardian mobile app, offering remote monitoring, performance insights, and firmware updates from anywhere. Approved by utilities across the U.S. and Puerto Rico, the Envy 8/10kW also enables participation in Virtual Power Plant (VPP) programs, allowing you to earn compensation for discharging energy back to the grid during periods of high demand.
