Whole-Home Backup Power and Energy Independence

The Fortress Power Envy True is designed to help keep a home's electrical system operating when utility power becomes unavailable. When connected to a properly sized and compatible battery bank, the inverter can supply stored energy to household circuits during a grid outage.

Its whole-home pass-through architecture simplifies integration with a home's electrical service, while the inverter's independent backup output supplies power within its rated capacity when operating without the grid.

Homeowners can configure their systems to prioritize essential loads, solar self-consumption, or broader household backup depending on battery capacity, electrical demand, and installation design.

Integrated Solar Charging and Flexible PV Design

The Envy True includes built-in maximum power point tracking technology to manage energy from connected solar panels. Independent MPPT inputs help accommodate solar arrays with different orientations and electrical characteristics.

Solar energy can be directed toward household consumption, compatible battery charging, or grid export where permitted. The inverter also supports AC coupling, making it suitable for certain existing solar installations that are being upgraded with battery storage.

Compatible Battery Storage and Generator Integration

The Envy True is designed for compatible low-voltage lithium and lead-acid battery banks, including supported Fortress Power battery storage products.

Integrated battery management settings allow the inverter to coordinate charging and discharging based on system requirements. Battery communication and operating limits depend on the specific battery model and approved configuration.

A dedicated generator input provides another source of power during extended outages or periods of limited solar production. Automatic generator start support allows appropriately configured systems to incorporate generator operation into their backup strategy.

Advanced Energy Management and Monitoring

The Envy True offers configurable operating modes for solar self-consumption, time-of-use management, peak shaving, and zero-export applications.

Homeowners and installers can monitor system performance through the integrated color touchscreen and supported remote monitoring connections. Communication interfaces support compatible battery management systems and other energy equipment.

For larger installations, parallel operation allows additional compatible Envy True inverters to be incorporated into an expanded power system.
