DESS charges only 1-2 minutes per quarter due to hourly SOC target communicated every 15 minutes

This is likely a large part of the issue here. Are you able to use a BMV (0.1% reported SoC) as battery monitor? I use a BMV and reconstruct SoC using the much higher precision consumedAh value: 1 + ( consumedAh / capacity ), then populated a virtual battery with all BMV values except the improved SoC. That achieves real 0.01% precision and solved problems that looked much the same as yours. You might not even need a BMV for that depending on what your Seplos BMS reports.

This is an elegant solution to increase the SoC precision. Mine is already 0.1, but calculating it myself would in my case at least increase it 3 fold (330ah battery).

Is there an easy way to copy all DBUS values into the virtual battery? or do i really have to connect 20+ input nodes into it.

And I assume you have to select the newly created battery then as the battery monitor in the gx gui.
