I noticed a while ago that activating “ESS”/“Grid feed-in”/“DC-coupled PV - feed-in excess” and setting “Maximum feed-in” to 0W increases the DC voltage to ~52.5V or more.
Is it a bug or a feature?
Taking the above discussion about battery longevity, is it a good idea to activate this feature from time to time to increase the 100% voltage?

Feed in increases the voltage by a 0.4V offset (initially) as overvoltage is required to export power, the inverter will drag this offset down again.
Sorry.
“Exporting” up to a limit of 0W is a bit overstretched, but OK.
Thanks!
It still triggers the behaviour but it should settle with time, similar to setting a lower limit.
I see the same on mine, but it sorts itself out.
