Placement of AC-AC adapter

Hi All,

I'm currently thinking about to replace my pulse counting solution with the CT clamps, so that I can monitor true exporting of my PV system. One question that remains when reading this tutorial:

Does it matter where I place the AC adapter in the system? Now the PV system has it's own dedicated fusebox, and I can can create an outlet for attaching the AC adapter for this group if needed. But do I have to?

Re: Placement of AC-AC adapter

The ac adapter needs to measure the "correct" voltage!  Generally, that is taken to mean the voltage at your main intake. If you have a high current load on a long wire and measure the voltage near that load, the voltage will fluctuate according to whether the load is on or off. It is that kind of situation that you need to avoid.
