I have set up a 3 phase ESS system in Australia with 3 x Multigrid 24V 3000s and all works Ok except the house is 100m away from the install and has an MEN connection at its own distribution board, this is causing an error 11 fault. This is quite a common way to do installations in Australia. Is there a Firmware update to fix this one or any other way to resolve it?
The easiest fix is to keep the MEN link in the remote properties switchboard. But make sure that the MultiPlus is wired after the MEN link. See this document for more info: Neutral and MEN connections in the MultiGrid.pdf
Should you need a common nuetral in the installation, before and after the MultiPlus, we do have special firmware available that specifically deals with this issue, to get this please contact your Victron dealer or distributor.
Can you please post a wiring diagram. I am quite familiar with Error 11 issues.
Why can't you just move the MEN to where the Victron and main supply board is located? House board will then be fed by ACout (and utilise the ACout PE).
Ive updated to Firmware 455 and now receiving the error report saying its failed step 6, as the property is 100m away with its own MEN link and has to stay that way the only solution i can think of is to install a 4 pole contactor with a delay on so the neutral is broken until after the checks are done, unless there is another way.
