My setup are 2 5kW hybrid single fase inverters connected in parallel. ( true parallel connection ports )
Battery + and - poles are connected to both inverters. Bms port of the master inverter is connected to the battery. My external power meter is connected to the meter port of the master.
Everything is ok on the master . ( it can see grid import and home usage ) . On the slave on the other hand it's not ok. It doesn't see the grid import or home usage.
Where i live , we have a 3 fase delta grid electricity network what means it's a 3 fase network without a common N ( neuter ) . So i only have l1 , l2 and l3. And between each fase 230v. It's only allowed to connect 5kW on one fase. So i connected the master on fase 1 and 2 and the slave on fase 2 and 3.
Now here are the questions :
How do i set both inverters the best? Master on fase a setting and slave on fase b setting? Or both on fase a setting?
If i set them both on fase a setting i don't get grid or home usage readings on the slave inverter. And if i set slave to fase b setting it does see the readings of the grid and home usage , but after a few seconds i get the f18 error.
Than second question , is it normal that the slave inverter can't see the battery values like temperature ,etc? On the master i can see all values when i push on the bms button. On the slave no values.
Third question :
If you look at the picture i've included , you can see that pv is still produces around 670w and it's sending this power to the battery instead of my home usage. This makes the grid import 3 kW instead of 2.4kW. When there's more power needed from house load the battery should give power instead of loading . Don't understand why this is happening. On an other post on facebook some told be the power of the pv is to low and that's why the inverter sends it to the battery . Don't know if this info is true , because sometime the pv is higher than 1kW and still it's sending the power to the battery instead of my home usage. I want home usage to be covered as much as possible. So that i have to use the grid as minimum as possible.
Hope my questions are clair.
