We run an 8kW hybrid with 2 x 172Ah BSL LiFePO4 units. The CT is supposedly installed after the prepaid meter to allow for PV export to my non-essentials (geyser and oven). I tested this on a sunny day a few days ago, by unchecking "Limit to load only" on the System Mode settings. I then had some strange behaviour: It seemed that the excess PV indeed powered my home (essentials as well as non-essentials). However, the "Load" reading on my logger went to 0 and remained there. This can be seen in the screenshot below of the system:

One can see that I unchecked the "Limit to Load" around 14h00 to allow the PV to feed the system. Note that there was no loadshedding (AC was available). At 16h40 I checked "Limit to Load again", as it seemed as if the Load was then fully supplied by the Grid, even thoough I have a timer that should use the battery. When I checked "Limit to Load", you can see the battery is used to supply the Load, which could be measured again. Below is a zoom of the plot above.

Is this an issue with my CT? One thing I can mention is that the distance between my inverter and CT is quite long and I saw on some other info online that a long CT cable may be an issue?

Any insights or comments would be appreciated.
