Hi my name is Kevin. I need advise on a installation with 2 X 5kva Sunsynk inverters I have installed one on each phase and have the CTs on each phase at the meter box. The CT reading at this stage with very little load are 0 and as soon as I turn on the PV isolator it goes into negative numbers. Is it possible running back through the neutrals . Also what does the CT ratio need to be set at.
Please advise
