- Up to 6 HiBattery 1920 AC units
- 3-Phase Electrical system
- 2 / Phase Maximum units per phase
2. Connect HiBattery 1920 AC Units to the S-Miles Home App
After completing the hardware installation, each HiBattery 1920 AC must be connected to the S-Miles Home App individually.
Open the S-Miles Home App and follow the standard device setup procedure to bind and connect the first HiBattery 1920 AC.
Repeat the same process for every additional HiBattery 1920 AC. Each unit must be bound and connected to the app separately.
Once all units have been successfully connected, the S-Miles Home App integrates their data into the same home energy system.
The app combines the operating and energy data from all connected HiBattery units, allowing you to monitor the overall household energy system.
