The Fortress Power Envy Duo 21 is a powerful 48V hybrid inverter designed to handle demanding residential and light commercial energy needs. With a maximum PV input of 25kW and dual-phase compatibility (240V split-phase and 208V three-phase), it delivers 12kW of continuous backup output power across both configurations, with max export power of 16kW.

The Fortress Power eBoost is a high-capacity, modular energy storage solution built for residential and light commercial applications. With 16kWh of usable energy per unit and the ability to scale up to 256kWh, eBoost is engineered to handle high load demands while offering the flexibility of single-battery or multiple-battery installations.

Built-in heating elements, an IP65 weatherproof enclosure, and integration with the eWay Wireway system allow for clean, all-weather installs.

Engineered for long-term durability, the eWay minimizes wiring clutter, reduces installation time, and enhances overall system safety. When paired with the eBoost, it provides installers with a comprehensive wire routing solution, keeping high-voltage and communication lines properly managed. Envy inverters bolt directly to the eWay eliminating the need for conduit between the battery and inverter.
