ET340 spikes on L3

Hi,

Im using a single MP2 at this moment for an ESS system with a ET340 grid meter. The multi is connected to L1. On L3 there is nothing connected but every now and then i got a spike of about 6000watts positive and negative, its about 3 or 4 times a day.

I recently replaced my ET340 cause i'd expect it to be broken but the same thing is still going on.

The weird thing, it is not visible on the VRM but when i read all values trough modbus TCP i find this back in my logging on Grafana.

Thanks and regards!
