Unfortunately, I'm not able to install current clamps on both the "produced" power and the "consumed" power. The only option I have is to install a current clamp on the total power. I do have an in circuit meter ("GSC" counter) available, so I wonder if it would be possible to properly seperate both powers by taking into account these 2 measurements.
So to resume:
clamp 1=power as close as possible to my energy supplier
GSC output=generated output of the PV installation (type EM10din)
Is the device capable of graphing (clamp1-GSC power)? Are they measured synchronously?
