Frequently Asked Questions

What does true 12kW mean compared to other inverters?+
Many inverters advertise 12kW but derate to 8-10kW under real-world conditions like heat or sustained load. The Envy True maintains a full 12kW continuous output without derating, giving you the power you actually paid for.
Do I still need a separate breaker panel with the Envy True?+
The Envy True has integrated breakers built in, which simplifies installation and reduces the number of components in your electrical system. Your installer can advise on your specific panel requirements.
Is the Envy True compatible with Fortress Power batteries?+
Yes. The Envy True is designed to pair with the full Fortress Power LFP battery lineup including the eFlex, eVault, and eForce series for seamless whole-home energy storage.
Can I use the Envy True for both grid-tied and off-grid setups?+
Yes. The Envy True operates in grid-tied, off-grid, and hybrid modes, automatically switching between them as conditions change to keep your home powered.
