ECO-ESS Automatic Transfer Switch

Which version do you have?

Your ECO-ESS ATS comes in two versions. Check the label inside your fuse box — it shows v1.0 or v1.1. The setup procedure is different, so make sure you pick the right guide.

v1.0

Version 1.0 Guide

Shipped before 17 April 2026. Wi-Fi changes need a Windows laptop.

 v1.1

Version 1.1 Guide

Shipped from 17 April 2026 onwards. Wi-Fi changes can be done from your phone.
No version on your label? Early units don't have the version printed. If your unit was installed before 17 April 2026, you have v1.0.
Not sure which one you have? Contact ECO-ESS support with your serial number (ECO-XXXX-XXXX on the unit label) and we'll confirm.
