| subcategory | high-voltage residential stacked battery SYSTEM (Base + BDU control unit + N HV9640 modules) |
| variant_note | SYSTEM-level record. Tower Pro TP15 = 4 x HV9640 battery modules on one Base + BDU. The 15.36 kWh / 384 V figures are SYSTEM figures; the module is 96 V / 40 Ah / 3.84 kWh (see the separate HV9640 record). Tower Pro is a 1C system (max charge and discharge power in kW equals the rated energy in kWh); the older Tower series is not. |
