Fortress Power > True Envy 12kW Inverter, 16.2 kWh (315AH) eFlex Batteries and FlexTower Enclosure All-in-One Energy Storage System - Indoor / Outdoor Enclosure

Manufacturer Part Number: Fortress Power Envy 12k FlexTower 16.2kWh Bundled Kit

The Fortress Power Envy True 12kW and three eFlex 5.4 Batteries in a FlexTower Indoor / Outdoor Enclosure offer a simple, All-In-One energy storage solution for your home. Adding a Fortress inverter and battery storage system to your home PV system is simple. Fortress Battery provides a combined solution that will help you keep the lights on and your home office running during utility interruptions. "Closed-loop" communication and streamlined installation make integrating solar with storage now easier than ever.

Fortress Power Battery Monitoring Gateway for eFlex Batteries also included.
The Fortress Power Guardian is a gateway device that connects Fortress Power Batteries to the cloud. Paired with the companion app, the Guardian will automatically discover connected Fortress Power batteries. This enables battery-level monitoring of key values such as State of Charge, Voltage, Current and Battery Temperature as well as faster, more accurate technical support. Remotely update battery firmware, submit support tickets, chat live with technical support, complete warranty submissions, and securely share installation and monitoring data directly with support engineers– right from the companion app.

NOTICE: eFlex and eVault batteries will likely need a firmware update when being paired with the Fortress Envy inverter. Software download required. Communication cable provided by Fortress Power upon request. Can be used repeatedly for multiple projects.
