Multiplus 2 MEN Earth Neutral link

We are offering our customers the Multiplus 2 coupled with a Fronius GT inverter. We have struck some problems when they have an outbuilding with a MEN link(earth - Neutral) in the sub-board.

The Multi will go into error when the grid tries to connect(it's ok if stand-alone)

I understand there is a Temporary firmware patch for this issue. Is this going to be a permanent solution? We don't want to have to go back and reprogram in the future if it is only temporary.


Thanks Dean

Hi @Dean_D,

The permanent solution was included in MultiPlus-II Firmware 466 and beyond.

There is further explanation here:
