| variant_note | STACK100 is a SYSTEM name, not a single module. One cluster = a BDU/base plus 3-15 battery modules of 51.2V/100Ah (5.12 kWh each), giving 15.36-76.8 kWh per cluster. Up to 12 clusters in parallel. nominal_energy_kwh is therefore left UNKNOWN at system level; see module_* fields and system_energy_min/max_kwh. |
