APsystems ECU-R — Zigbee to Wi-Fi Monitoring Gateway

The APsystems ECU-R is the required communications gateway for all APsystems DS3 microinverter installations. It collects real-time performance data from each microinverter via the Zigbee wireless network, translates it to your home Wi-Fi, and uploads to the APsystems EMA cloud platform — giving you panel-by-panel production monitoring from any device, anywhere.

One ECU-R handles up to 30 DS3 units (60 solar panels), making it suitable for most residential and small commercial installations. Setup is simple: plug it in, connect to your Wi-Fi, and your entire array is visible in the EMA app within minutes.
