CT Clamp for PV monitoring

Hi all,

I have an AC1 inverter installed, with EP11 battery to compliment my existing solar PV system that was installed under the old FiT scheme.

My installer only installed 1 CT clamp to the load of the house at the meter into pins 7 & 8. However, I have read that by connecting a second CT clamp to pins 5 & 6 of the inverter I can also enable the inverter to monitor the PV.

However, my existing PV array is made of 2 strings with an inverter on each. So I have 2 feeds into my CU from the solar. I suspect the CT clamp would only monitor one. Is there any easy way I could get this to work?

Thanks,

Steve
