high-voltage residential stacked battery SYSTEM (BDU control unit + N HV9637S modules)
|
| variant_note |
SYSTEM-level record. Tower S3 TS7 = 2 x HV9637S modules on one BDU. Same 37 Ah / 3.552 kWh module electrical class as the older Tower series but a different module part number (HV9637S vs HV9637), slightly lower system weight and a 20 mm taller enclosure per module step. The S3 system voltage range tops out at 108 V per module (216 V), 9 V per module lower than the older Tower's 219 V for the same module count.
