Scope notes

This V8 app is the BESS layout, map, SLD and financial screening frame.

It intentionally excludes cable sizing, cable impedance, thermal derating, reverse current calculation, leakage calculation, fault withstand and protection coordination. Those belong in the advanced BESS Electrical Topology Review.

Future advanced versions should allow a client substation footprint, customer switchroom, MV compound or HV interface area to be drawn and sized as a separate grid connection zone. This is intentionally excluded from the first BESS layout version to keep the app focused on BESS containers, PCS blocks, transformer arrangement, access and commercial screening.
