"With In Rush"?! - Battery Modules Required - Premium LVL 15.4

Our system to begin installation ASAP:

- Off-Grid 3-phase Quattro 10KVA system with 3 LVL Modules.

In the Victron BYD Compatibility page, there is a table that shows the minimum number of modules per inverter type. There is no explanation to the "with in rush" part of the column. Can someone please explain this in more detail? (I'm not looking for a basic explanation of what in-rush current is.) I'd like to know... will 3 LVL modules be enough to turn on the Quattro's? Am I correct in assuming yes but without the ability to supply loads immediately as the inverters turn-on?

This explained just a little bit further down the page that you are reading, just below the chart for the Premium LVS 4.0.

“With inrush” - this is the advice for systems that have load profiles that use the full surge capacity of the inverter, eg Multiplus 48/5000/70 providing 10 kW for 5 seconds to start an electric motor.
