Mulitplus 2 AC internal sensor reading high all the time when a PV inverter connected to AC2 output
When i plug in a external AC sensor the current is of the correct value, when no load is there it reads zero watts, But if i use the internal current sensor when no loads are there it always reads 7 to 10watts of power with the PV inverter connected it can read higher to about 20watts more.
The AC sensor is in the same place as the internal one, in the AC in All that the external ones is disconnect the internal one.
So what this does it keeps the inverter running all the time, as it see power being drawn when there is none.
I have wired the PV inverter in different place AC1 out and AC in still the same results, The internal CT has a issue, were as the external one performs as expected, No loads shows no power which you would expect.
Is it a internal calibration error?
