Unstable temperature reading

Hi,

I have a 3 phase installation with 3 MP II 10000, PV and battery. Did use the temperature sensors that comes with the mullties and connected these to the Cerbo for room temperature monitoring at various positions.

The ESS was configured for multiphase regulation. ESS was changed to single phase regulation, after which spikes on the temperature sensors are observed. How can this be? This does not make sense. The spikes observed are considerable.

It looks like electrical noise generated by high current switching?

Have you tried re-routing the sensor cabling away from high current cabling?
