I upped the current on my ' 9 fet' version of KT controller. I expected the LCD3 to read the same watts as before because I assumed that it derives the current reading from the same shunt. But no, it looks like it is showing the increased wattage due to my shunt mod. So where is it getting it's measurements from then ? I only know of one shunt. It's a ZWS controller so I don't think it has phase current sensors or anything.
