Linking Multiple Devices into a Single Virtual Device

In scenarios where the total cable diameter does not allow measuring current with a single CT ring, the current must be split across multiple CT rings and meters. A new capability allows linking multiple meters into one virtual meter so the system treats them as a single logical device.

This configuration is handled at the device level, while the cloud aggregates and presents the values correctly.

• Multiple CT rings are required to measure total current.

• Each CT ring is connected to a separate DC meter.

• The meters must be represented as one meter in the system.

1. Virtual ID Configuration

   • Configure all relevant meters with the same Virtual Device ID.
     Example:

     • Solar use case: Virtual ID = 34

     • Any other use case: use the required Virtual ID.

Open

2. Linked Device Setting

   • Select one of the meters and mark it as Linked Device in the Modbus Device Configuration.

   • All other meters remain unlinked but share the same Virtual ID.

Open

After configuration:

• Connection Status:

  • The aggregated virtual meter will be displayed as Connected if at least one of the linked devices is in Connected status (OR logic).

• Total Output KWH: Displayed value is the sum of total energy from all linked meters.

• Voltage: Displayed value is the maximum voltage among all linked meters.

• Current: Displayed value is the sum of currents from all linked meters.

The cloud automatically handles aggregation and presents correct values as if coming from a single physical meter.

• You can link more than two meters — link as many as required.

• This mechanism is not limited to CE DC Multi-Channel meters.

• Any supported meter type can be linked using this method.
