Fortress Power Envy WLAN Dongle, Wi-Fi Monitoring Module for Envy 8kW, 10kW, and 12kW Inverters, Remote Monitoring via Fortress Power App

The Fortress Power Envy WLAN Dongle is a plug-in Wi-Fi module that enables wireless remote monitoring for the Fortress Power Envy line of hybrid inverters. It is compatible with the Envy 8kW, Envy 10kW, and Envy 12kW models. Without this dongle, the Envy inverter can only be monitored and configured locally through its built-in LCD screen. With the dongle installed, homeowners and installers gain remote access to real-time system data from anywhere with an internet connection.

How It Works

The dongle plugs directly into the communication port on the Envy inverter while the inverter is energized. Once connected, the dongle broadcasts its own temporary Wi-Fi network (named "BA" followed by the dongle's serial number). Using the Envy Fortress Power mobile app (available on both iOS and Android), the installer connects to this temporary network, enters the home Wi-Fi router's SSID and password, and the dongle bridges to the home network. When the connection is successful, the dongle displays three solid LED indicator lights. The entire setup process typically takes just a few minutes.

Monitoring and Access

Once connected, the dongle transmits inverter data to the Fortress Power monitoring platform. Homeowners can log into the Envy Fortress Power app or the web portal at envy.fortresspower.io to view real-time information including power flow direction, solar production, battery SOC (State of Charge), grid export, and total consumption. Installers can register systems under their customer code so that every installation they complete is reflected in their installer portal, giving them visibility across all of their deployed systems.

The web portal method is the recommended approach for initial registration and system configuration. Installers log in at envy.fortresspower.io, create a station (plant name), associate the dongle by entering its serial number and PIN (both printed on the side of the dongle and on the packaging), and then set up end-user access with either full or read-only permissions.

Important Notes

The WLAN dongle is a monitoring and registration accessory. The Envy inverter operates fully without it. Removing or disconnecting the dongle does not affect the inverter's ability to charge batteries, power loads, or manage power sources. It only removes the remote monitoring capability.

One dongle is required per inverter. In parallel installations with multiple Envy units, each inverter needs its own dongle for full system visibility through the monitoring platform.
