Error: mk2vsc-33 on Multiplus 3000/120 230v 50 amp

This is happening when using the VRM and downloading the multiplus setup

this started to happen on firmware 487, with a VE BMS assistant installed - But the ve-BMS was unplugged and I was trying to do a remote update/upgrade the fw to 489 but this stalled at 20.5%

thinking it was a remote upgrade issue - I have done the below

so now I have manually upgraded the firmware to 489 by going to site. thinking this would fix the issue

we have a cerbo connected on 2.80~24 (also connected to the VRM)

we have one VE-BMS connected

there is NOW no assistant installed as 489 FW does not require it with the new tick box ticked and the ve-bms is working correctly as when I unplug the VE-bus cable from the VE-BMS the inverter shows low bat and switch's to pass through as it should.

so everything is working on site and the vrm and remote console is working but I still get this error : Error: mk2vsc-33

but the below error still occurs when I try to download the setup

Anyone got any ideas as to how to overcome this issue

Up to 8 attachments (including images) can be used with a maximum of 190.8 MiB each and 286.6 MiB total.

anyone got a idea here, I suspect maybe a VRM block of some type on remote updating/download ????

Hi Paul, its (most likely) a known issue in the beta firmware. Please next time report it there, thanks!


for now, to fix this, use the latest official release, v2.73
