Post by wifi75 » Thu Sep 12, 2019 7:21 am

Hello I've installed couter sdm230 for PV and one sdm230 couter for the consumption.
the value of production is now negative why?
in Italy in the north it is now 8.30 am

Hi,
It's either your meter or the com. app. that return a negative value. You can trick the protocol file to avoid these samples.
:idea: Maybe it's because you don't produce yet and your inverter consume a bit of power.
