Connect Your Envy Inverter Online Over 4G Cellular

The Fortress Envy 4G Dongle gives your Fortress Power Envy inverter a 4G internet connection. Fortress lists it under part number ENVY4GDONGLE.

It is the cellular alternative to the Envy Wi-Fi dongle, for sites where Wi-Fi does not reach the inverter. This item is special order.

Why You'll Love The Fortress Envy 4G Dongle

No Wi-Fi needed. A 4G cellular connection gets your inverter online at cabins, barns and remote sites.

Keep an eye on your system. An internet connection lets you and your installer check on the system without a site visit.

Made for the Envy. A Fortress Power part for the Envy inverter line.

Simple add-on. One small part solves a connectivity problem.

Your life, with the Fortress Envy 4G Dongle

Your inverter sits in an outbuilding far from the router. With the 4G dongle it stays online anyway, so you can check in from your phone and your installer can help without driving out.
