MultiPlus 20K-CL: Parallel operation limits and “Microgrid Cluster” feature?

Q&A and troubleshooting

Hi all,

I’m planning a larger 3-phase system using the new MultiPlus-CL 48/20k units and need clarity on two points that I can’t find in any official Victron documentation:

  1. How many MultiPlus 20K-CL units can be paralleled per phase? Some resellers claim up to 4 per phase (i.e. 12 units / 240 kW in a 3-phase setup), but I haven’t found this confirmed in any Victron datasheet or manual. The datasheet only says “virtually unlimited power thanks to parallel and three phase operation” without specifying an actual limit.

  2. What exactly is the “Microgrid Cluster” feature that some resellers list as “out soon”? Is this a new approach to paralleling that goes beyond the traditional VE.Bus parallel configuration? Does it replace or extend the classic parallel setup?

For context: I’m currently running Quattro 15K systems (up to 4 units per phase, 12 total) and looking to upgrade. The 20 kW true output per unit is very attractive, but I need to confirm that a similar or better parallel topology is actually supported before committing.

Any official info or hands-on experience would be greatly appreciated. Thanks!

Yes. The cluster system uses the ACin to connect multiple sets together, forming a microgrid on the AC input side. However ive only watched the interview with Guy on youtube. But i assume what he explains is as official as it gets

cheers, man, very educational video. too bad I did not find it earlier. I was even at the same tradeshow but it seems I missed the good talks there.
Anyhow, questions answered, I will now build some bigger systems it seems.

I think without the micro grid/cluster feature it has the same limitations as the other VE.Bus devices.

But the 20K will not be available for the next few months.

Yes, i heard first shipment is supposed to be mid/end of Q2.
And yes again: It seems we have the same limitations as with the other systems.
Here is a screenshot from the video:
