Multi-orientation daily-sharing with several onduleur same reference

[tommm]

Hi,

I have a question about the Multi-orientation daily-sharing tool.

I’m working with three identical inverters, each with 12 MPPT inputs, and 4 different orientations (one for each direction). I’ve already built all my sub-arrays with the correct number of MPPTs, and the Power Sharing window works fine.

Since my inverters are heavily oversized (400 kWp for 250 kVA), I assume that power sharing is a crucial aspect of this design.

The Multi-orientation daily-sharing window seems to be exactly what I need, as it allows the inverter to dynamically share power between MPPTs with very different orientations.

However, I’ve encountered a problem: in this window, all MPPTs appear to be grouped under a single large inverter, and there doesn't seem to be a way to group MPPTs by inverter, like in the Power Sharing window.

Is my understanding correct?
Is there really no way to organize MPPTs by individual inverter in this interface?

I also tried duplicating the .OND file to create another inverter type, hoping it would help. But now, in the daily sharing window, I only see the MPPTs corresponding to the inverter selected in the system definition (not all MPPTs from the project).

Thanks for your help!

Best regards,

Hi @tommm, no indeed, as you have understood, there is no way to organize per inverters in this interface.

However, the solution you hinted at should work. I.e., you can define different inverters and open the window “Multi-orientation daily sharing” from sub-arrays with the three different inverters respectively. Make sure everything is checked.
