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