his article explains how to commission the EI Residential System in the EU using the EI App. It is intended for installers and technicians and outlines the key commissioning steps, including connecting to the system, configuring settings, and verifying the installation is ready for use.
Before You Begin
Commissioning requires a strong, stable internet connection at the site. Confirm the following before opening the app:
- The EI Inverter, battery, ATS, energy meter, generator, and TS4 equipment are installed and powered as required for commissioning.
- Install the latest version of the Tigo Energy Intelligence (EI) app on the mobile device used for commissioning. Download or update the app by searching for “Tigo Energy Intelligence” in the Apple App Store (iOS) or the Google Play Store (Android).
- You have an installer-level Tigo account and the customer network credentials.
- Enable Bluetooth, location, and camera permissions on the mobile device.
- Equipment serial numbers and barcodes are accessible.
- For monitored TS4 systems, the paper map matches the installed array.
1. Sign In and Start a New System
1. Open the Tigo EI App and sign in. If you do not have an account, tap Enroll and follow the prompts to verify your email address.
2. On the Installations screen, tap the plus sign in the upper-right corner to create a new system.
