As demand for battery backup and energy storage continues to grow, installers need solutions that are flexible, scalable, and easy to deploy across a variety of applications. That’s why more installers are turning to the combination of Fortress Power’s Envy inverter lineup and eBoost energy storage system. Together, they create a streamlined solution that supports everything from residential backup power to light commercial energy storage while giving installers the flexibility to design systems around each customer’s unique needs.
One Platform, Multiple Possibilities
Every project is different. Some homeowners want whole-home backup. Others want to keep only critical loads running during an outage. Some systems include solar, while others require generator integration or future battery expansion.
The Envy inverter platform is designed to support those scenarios without forcing installers into a one-size-fits-all approach.
Available in 8 kW, 10 kW, and 12 kW models, as well as the Envy Duo 21 kW hybrid inverter, the lineup gives installers the flexibility to match inverter capacity to the project while maintaining a familiar platform across installations.
Paired with eBoost, the result is a complete energy storage solution capable of supporting grid-tied, backup, off-grid, solar, and generator-assisted applications.
Scalable Storage That Grows With the Project
One of eBoost’s biggest advantages is scalability. Each unit provides 16 kWh of usable LFP battery storage, making it suitable for residential and light commercial applications. Whether the goal is critical-load backup or larger energy storage capacity, installers can build systems around the customer’s current needs while leaving room for future expansion.
With support for up to 384 kWh of storage using the latest firmware, eBoost allows installers to scale projects without redesigning the entire system. That flexibility can help simplify system planning while giving customers confidence that their energy storage investment can grow alongside future energy demands. This will energize the inverter and prepare the system for setup.
Designed for Real-World Installations
Installers know that product features only matter if they make the job easier. eBoost includes several practical design elements that help streamline installation and deployment. Built-in wheels make positioning and moving the unit easier on-site, while the system’s clean design helps reduce visible wiring for a more professional finished installation.
The battery is also IP65-rated, providing protection against dust and water intrusion for indoor or outdoor installations. This gives installers greater flexibility when determining system placement without sacrificing durability.
Built for Challenging Environments
Not every installation takes place in ideal weather conditions. That’s why eBoost includes integrated battery heating technology designed to help maintain battery performance in colder climates. The system automatically helps protect the battery during low-temperature conditions, supporting reliable operation when customers need backup power most.
Combined with its weather-resistant enclosure, eBoost is designed to perform across a wide range of installation environments.
Reliable Backup Power When It Matters Most
At the end of the day, customers aren’t buying batteries or inverters. They’re buying reliability. When paired together, Envy and eBoost help ensure essential loads remain powered during grid outages. Lights stay on, refrigerators continue running, internet connections remain active, and homeowners gain greater confidence in their energy security.
For installers, that means delivering a solution that not only performs on paper but also provides real-world value when outages occur.
A Flexible Energy Storage Solution for Today’s Market
As backup power, self-consumption, and energy independence become increasingly important, installers need products that can adapt to evolving customer requirements.
The combination of Fortress Power’s Envy inverter platform and eBoost energy storage system delivers the flexibility, scalability, and installer-friendly design needed to support a wide range of residential and light commercial applications.
Whether you’re designing a solar-plus-storage system, building a backup power solution, or planning for future expansion, Envy and eBoost provide a powerful foundation for modern energy storage projects. Get started today.
