CT ratio for 50kW hybrid inverter
Does anyone know what the CT ratio for the standard CT coils that come with the inverter. The software is set to 6000:1 as default in advanced settings. The readings are not accurate as reported on inverter screen when measured with a tong meter.

While Keith rabbits on about CT coils, they can be a bit of an issue.
Firstly I would be surprised that they use different CT coil ratio on this inverter, but it is a BIG inverter. As Flipper said, the raito for the 5 and 8kW systems is 2000:1. You can always try it that setting and see if works.
The other thing that you need to make sure is the direction of the arrow on the CT. It is a known fact that sometimes they do not work as described and you have to either reverse the connection (white and black cables) or just reverse the CT coil. In fact the manual even says this "When the reading of the load power on the LCD is not correct, please reverse the CT arrow."
