Good Morning David. Hope you are having a good weekend. My good friend came over yesterday and assisted with the clamp meter readings.

I changed the CT to 50 from 40 and i can then get the meter check to work and the meter check says meter correct, however s few seconds later the meter check fails, all during this the invertor is playing up very badly. now set back to 40

Thanks Dave.

the Meter is a DTSU666

when in the inverter meter setting there is an option to "check Meter" which returns "Meter Wrong"

how do i set the invertor meter settings to be 3 phase. it only has setting for Meter 1 and Meter 2. also when looking at running/Grid. it shows all 3 phases R,S & T
