Updating Multiplus firmware with VE.BMS BMS on Lithium bank

Hi,

I'm trying to update the firmware on my Multiplus, but it says to disconnect the BMS. If I do that it will shut down the multiplus, so bit of a catch 22.


Do I need to remove the Lithium/Assist settings, disconnect the BMS and then do the update and put the Lithium/Assist setting back once the update completes?


Thanks,


Michael

Just continue with the update process. The Multi shouldn't be turned off completely without the BMS.

If it is a Compact Multi you may have to switch the DIP-switches back to default for the update process.

Thanks Matthias - I thought I'd disconnected the BMS before and the Multi shutdown - Guess not I'll unplug the BMS and see what happens. Regards, Michael
