MCB trips on MULTIPLUS 2 feed in stacked configuration, what are the conquences?

Reading the Victron wiring documentation.


Where double pole isolation is required for invertors, what would happen if you have 2 stacked Multiplus 2 running from LYNX Distributer each with their own Double pole MCB. An over current fault occurs on only one of the Multiplus II invertors and the MCB trips both negative and postive feed to the invertor.


Acording to the Victron documentation this is bad for the Ve.Can comms and can damage the internal board on all the connected devices as the negative is removed on one of the Multiplus II but not on the other Multiplus II.

Could we clarify how to avoid this situation as each Multiplus II needs it's own overcurrent protection. Switching the stack off with one main OC MCB device parallelled does not suffice as it won't protect each Multipluss at the OC specified rating.

regards


Multiplus-II
