Short circuit current calculation at MV bus (34.5kV), Tesla Megapack

[adityalagudu3291]

In the process of calculating SCC at MV bus for a BESS plant. Utility POI fault current is at 40kA. Our only MPT size is 230/34.5, 210/280/350MVA, %Z = 10.5 @210MVA. Based on this the SCC at MV bus is coming around 30kA.

From the BESS Inverter side planning to use TESLA MP2XL megapack rated for 1100KVA, 480V, 979kW and MP2XL qty is 300. What is the Short circuit current contribution by all these Inverters at the MV bus level?

I would ask Tesla to provide some kind of documentation. I don't know of any IEEE papers that cover above IEEE 1547. You will most likely have to create your own modeling.

Thanks, checking with them too.
