Couple of days ago Multiplus II 3000 230V got software update. Before that charging was at 1500W. Now it ramps up for a minute, then lowers to ~150W. Fan is not running so might relate to that. So did the update broke the Multiplus?

Charge rate seems diminished after BMV update
Did you reload the configuration which is lost after the update (as per documented process)?
...are your batteries full?
The BMV-712 FW update has nothing to do with your MultiPlus charge rate, so either your batteries are (mostly) full or something else changed on the system, at which point you'll need to either contact your systems installer or, alternatively, grab a multimeter and start tracing lines and checking that all connections are good and etc.
Don't know what happened but after power off/on Multiplus is working again.
