It’s normal operation. During initialisation Imeon performs phase verification procedure to check if its phase No. 1 of the AC Grid Connector input corresponds to phase No. 1 connected to the Smart Meter. In order to do this, during 30s Imeon injects 2kW to one phase after another, and cross-checks it with the response detected by the SmartMeter. This is done to make sure that all phases are correctly identified, at the SmartMeter and Imeon inputs.
