Hi All.
I am trying to wire in a watt meter to my system. The meter is a CHINT DDSU666-H MONO. Single phase. There was no wiring diagram with the meter. I found several diagrams courtesy of 'Google'. However they all conflict.
I am wiring it to a Solax X1 Air, but the model should make no difference. The LAN control connection from the inverter is contacts 4 and 5 to the Chint connections 24 and 25 respectively. So thats fine. It does not employ a CT.
The problem is the Live and neutral connections.
One diagram shows inverter output Live to terminal 3 and neutral to terminal4. Power grid Live to terminal 1 and neutral to terminal 2.
A second diagram shows inverter output live to terminal 1 and neutral to terminal 3. power grid live to terminal 2 and neutral to terminal 4. (I favour this one)
Hence there is some confusion on my part.
I have attached a few images chint 3.jpgchint 1.jpgchint wiring.jpg
