1 year ago you would get more responses if you posted on a solar forum regarding this, this is just a codebase that attempts to talk to the inverter and get information (and for some inverters allows you to change settings)
i dont fully grasp your problem, but at a guess your batteries might be sagging at 2KW to the point that the inverter switches to AC, from my understanding the inverter has a max output of 4KW after which it may fail completely, even in bypass

Dear friends,
Maybe someone is reading along who can help me. My inverter is the type from EASUN mentioned above and should only use the bypass and the connected network of my house when it exceeds 4000 watts or 5000 VA. However, it does it at 2000 watts. What am I doing wrong?
My configuration: 4 * 12 Volt / 100 Ah battery approx. 1700 watts of solar
