You changed the AC inputs to posts. I wish the MPPT controllers were like this. When using 6awg the connections are so close.

Nope. :-)


There's something else very wrong with that image.

Interesting. I'm guessing the Quattro has male connectors for the AC connections and maybe my Multi doesn't.

AC IN2 is missing -> RMA

That would have been the better alternative.

Unfortunately, that is how the Quattro came back from RMA.

We called it our little "gender change" Quattro.

So yeah. After the power PCB in our test Quattro decided to have a smoking break and the Quattro came back from RMA "gender changed", we agreed with the Victron Service that it's better to send us just the connect PCB rather than sending 35kg of toroidal transformer around...

So together with some excellent HowTo:

(right MultiPlus PCB, left the spare part we got)

Real men repair the Quattros themselves. ;-)

I removed the serial numbers, because the last thing I'd like would be to get the service shop in trouble. Actually thanks to them we are fairly confident to repair any (old) Quattro or Multiplus.

The devices have a very nice modular concept.

The experience from all this begs the question if a MultiPlus -> Quattro upgrade is possible.

I mean, technically evidently yes: You change the connection PCB, the firmware - and if you have some sense for aesthetics also the front panel. Et voila! - you have a Quattro.

Use case could be an installation with MultiPlus devices which now needs an upgrade with an additional AC-IN (e.g. retrofit of an installation with a CHP or other type of Generator).

Of course, simply changing the device is faster and if one can agree with the customer a trade-in for the "old" MultiPlus, probably the preferred way to go, but in principle the option seems to be there.
