| subcategory | battery control unit / BDU for a stacked high-voltage battery tower (stack BMS + DC breaker + external DC terminals + inverter communication port) |
| variant_note | CONTROL UNIT only - no stored energy. The fetched Tower S3 user manual documents it as a distinct component (interface definitions in Table 2-5, inverter port pinout in Table 2-7) but prints NO model designation, weight, dimensions or separate electrical table for it. A distributor product titled 'DYNESS Control Module Tower S3 SBDU+BASE' was seen in search results but no page for it was successfully fetched, so 'SBDU' is NOT recorded as the part name. |
