New power wall Mures

Umm sounds strange. You are measuring the AC side after your PV inverters and not the DC side of you PV.

I emailed Sofar and they sent me a download link for the firmware

I found the problem clamp should be only on the line wire, initially null and ground was in the clamp… my mistake I didn’t read very carefully diagram from Sofar

Yes, I have 2 inverters both on grid and are 30m away in the back yard, that is why I measure AC production on the main cable from PV.

I’ve got the email with the firmware from the local seller, sofar didn’t respond directly to my email. Anyway system is working fine, I’ve added a new row of cells, now a total of 840 cells in 14s60, self usage has now increased from 25% to 60% with just a few days of sun. I’ll have to add more cells to increase storage capacity and also to grow charge/discharge, now I’ve set it to max 25A.
