SolarEdge has their own designer and you get acces to the C&I BESS if you pass some kind of exam (Dutch engineer who did it here).
Keep in mind this CSS outdoor is AC-coupled!
For the rest PV sol is much more detailed: for example datapoint in SE designer is 1hr which is not sufficient imo for peakshaving. For any SE system specifically I would go for a design trough their tool in the first place and later at 1min timeframe in PV sol for example.
Just look at 'Charge at the beginning' which is 369kWh which is 4 x [0,9 x 102kWh] (90% of capacity is actually useful). Therefore it is at least 4 BESS cabinets of 102kWh with in this case also 4 x 50kW AC-coupled (!!!) inverters.
If you want 2x50kW inverters with 4 BESS cabinet I suggest you copy the configuration and double the kWh's per 50kW inverter.
