Does anyone know what the behavior is of the Powelink PLE12D Meter when your inverter sells back to the grid - I've been warned that this could actually result in you paying for the electricity that you push back, other rumours where that the meter will turn back, and others mentioned that it has ZERO effect... I've tried to get the datasheet for this particular meter, but its very limited and doesnt really answer the question... Any thoughts ?

@P1000 - a huge thank you for your recommendation! It is finally working as expected (albeit that the CT reading is not 100%, the export / sell to grid has stopped) 🥳

Yes - its when Zero Export to CT is selected when things go wrong (unless the load is high enough), then it "works" (does not export to grid / sell to grid)

This is my current setup

Thank you P1000! So just to confirm , I should only use the one pair , splitting it for (-) & (+) ?

Ahhh.. OK

I have a two 5Kw DEYE Hybrid inverters setup which are connected to a sub-DB (located in my garage), and the main DB is located outside (at the swimming pool - about 50m away), and to which my heatpump and pump is connected to. The installers installed a CT to allow export from the inverters back to the main db to include the swimming pool and heatpump under my solar system. This seemingly worked fine, until I found that the CT reading goes into the negative when the pumps are not running resulting in the system pushing (selling) electricity back into the grid. When the pumps are switched on again the CT shows a (+) load and no electricity are exported back into the grid. After many phone calls it was suggested that the type of cable (1.5mm Surfix) used is not right for extending CTs that far, it was suggested that a CAT6 / paired data cable be used - which I've done, but the result (albeit that CT readings are less wrong) is still incorrect. i.e. it will indicate a -400W CT reading , but the load for the entire building (main & sub DBs) are roughly 1700W. I've tried the following suggestions with no obvious improvements: Replaced 1.5 Surfix CT cable with CAT6 cable (using a pair for negative, and a pair for the postive) Moved CT cables from slot 3&4 to 5&6 on inverter Swapped the direction of the CT Swapped the cables (positive & negative) around on the inverter Set export power to 0 on inverter settings Set selling power to 0 on inverter settings Replaced CT (same make & model) My thoughts are that the CT reading on the inverter is wrong. Any suggestions would be greatly appreciated! NB
