Fortress Power Plug-and-Play Solar Storage System

Complete Hybrid Energy Storage Solution with Smart Monitoring with Extended 15-Year Battery Warranty

Experience true energy independence with this Fortress Power hybrid system — a fully integrated, plug-and-play solar storage package engineered for simplicity, flexibility, and long-term performance. Designed for homes, farms, and small commercial applications, it combines smart power conversion, scalable energy storage, and advanced monitoring into one seamless solution.

How These Work Together

This system integrates the Fortress Power Envy True 12 kW Hybrid Inverter, Fortress Power eForce 9.6 kWh Stackable Batteries, the Fortress Guardian Gateway, and the Fortress eWay and Base system for clean, modular installation.

1. Fortress Envy 12 kW Hybrid Inverter serves as the system’s command center — converting DC solar power to AC for household use, while managing battery charging and grid interaction.

2. Fortress eForce 9.6 kWh Batteries provide reliable energy storage, automatically charging during the day and discharging when solar production drops or during outages.

3. The Guardian Gateway connects your system to the cloud for live monitoring, firmware updates, and smart control. It also enables participation in Virtual Power Plant (VPP) programs where available.

4. When the Guardian Gateway is installed, it extends the battery warranty from 10 years to 15 years, providing maximum protection and peace of mind.

5. The eWay and Base System simplifies installation, offering a secure, plug-and-play foundation for stacking multiple eForce batteries.

Together, these components create a flexible hybrid power platform ready for both grid-tied and off-grid operation — optimized for safety, longevity, and scalability.

Key Technology

Fortress Power Envy True 12 kW Hybrid Inverter
A high-performance hybrid inverter designed to handle solar, grid, generator, and battery power simultaneously.
