Hi, my first post so hopefully it makes sense.
I have a three phase supply, four wire 3+N in the uk, most of the base property load is on L3.
There is a single phase Solis 6K hybrid on L3 with 4 pylon tech US5000's and a 5k pv array on the solis mppt port 1, the inverter is connected via rs485 to an Eastron SDM360MCT three phase meter which is configured in the Solis
The CT clamps are genuine Eastron T24 100/5 and this is set in the meter and the ratio is also set to 20 (100/5)
selecting kW shows a typical load as
L1: 00:06
L2: 00:10
L3: -00:16
On the Solis information page the info is shown as ABC and it appears on the main hybrid display with a 0.00 import / export
Phase A -000062W
Phase B -000100W
Phase C +000165W
All good so far however the DNO meter via my IHD (hildebrand glow) shows a constant import of 42watts all the time the peaks of course are as expected with switching on loads etc but 42 watts all the time doesn't make sense.
If I force the time of use function to export at say 1 amp higher than the solis does on its own the dno meter goes to 0
Removing the SDM360MCT and going with the single phase eastron meter switching off L1/L2 shows 0 on the solis and 0 on the dno IHD
I have raised a case with solis but so far no explanation or resolution.
Any ideas?
Dave
