Not exporting up to configured limit

Hi

Installed Sunsynk SG04LP1 with 2x Synsynk 5.12 batteries and 6 kWp panels a couple of months ago. My export was setup a couple of weeks ago. I've configured the Max Sell Power = 3600 W. However I am consistently seeing that export is being limited to 3200 W for some reason. It is not because weather has changed - its been consistently sunny the past few days and the graph shows a smooth PV increase until export starts. But export max is always -3.2 rather than -3.6 as per my config. Not sure why? Am I missing something or is my expectation incorrect?

The CT ratio is 100A/50mA = 2000:1. This is a very big ratio which means the CT is not very accurate with lower currents. These types of CT coils cannot be used as accurate measurement device. The main function of the external CT coil is to limit the export of power from the inverter when using the "zero export" option, not to be confused with the internal CTs that monitor the power of the 3 ports, Grid, Load and Aux/Gen which produce the data used to produce the graphs and are used to calculate the "Maximum Selling" power or depending on the version of firmware you have, is referred as the "Inverter Power Limiter"
