| subcategory | utility-scale bidirectional MV power conversion system (turnkey PCS skid) |
| variant_note | Datasheet describes it as 'MV Power Converter optimized for ST2236UX-US / ST2752UX-US'. Family siblings named on Sungrow's PCS index include SC2750UD-MV, SC3150UD-MV, SC3450UD-MV, SC5000UD-MV - none of those datasheets were fetched. |

| efficiency_note | TWO distinct efficiency rows: 'Max. Converter Unit Efficiency 99.0%' and 'Max. Efficiency (including transformer) 98.3%'. Both preserved - quoting only the 99% would overstate the delivered skid efficiency. |
| expansion_rules | UNKNOWN |
| firmware_requirements | UNKNOWN |
| frequency_range_hz | 55 ~ 65 |
| grid_services | L/HVRT, FRT, soft start/stop, specified power factor control and reactive power support; Volt-var, Volt-watt, Frequency-watt control modes |

| system_energy_kwh | N/A |
| transformer_vector_group | Dy1 or Dy11 |
| usable_dod_pct | N/A |
| usable_energy_kwh | N/A |
Physical / mechanical
| cooling | Forced air cooling + KNAN |
| cooling_note | KNAN = mineral-oil-immersed, natural-convection-cooled transformer (IEC 60076 cooling class). Distinct from the liquid cooling of the battery units. |
| corrosion_grade | UNKNOWN |
| depth_mm | 2438 |
| dimensions_note | '6058 mm x 2896 mm x 2438 mm (238.3'' x 114.0'' x 96.0'')' - same 20-ft container footprint as the PowerTitan units |
| display | LED, WEB HMI |
| enclosure_rating | TYPE 3R |
| height_mm | 2896 |
| ip_note | Datasheet prints the NEMA enclosure rating 'TYPE 3R'. An IP54 equivalence was suggested by the fetch as an inference, NOT printed - so ip_rating records the printed NEMA rating only. |
| ip_rating | TYPE 3R |
| mounting | Containerised skid, outdoor |
| weight_kg | 17000 |
| weight_note | '17000 kg (37479 lbs)' |
| width_mm | 6058 |
Installation
| indoor_outdoor | Outdoor |
| mounting_method | Container/skid on foundation |
| supported_installation_topology | Paired with PowerTitan ST2236UX-US / ST2752UX-US battery containers |
Environment
| altitude_note | '1000 m standard / > 1000 m optional' - materially LOWER than the battery containers' 3000 m. |
| charge_temperature_c | N/A |
| discharge_temperature_c | N/A |
| humidity | 0 % ~ 100 % |
| indoor_outdoor | Outdoor |
| max_altitude_m | 1000 |

Protection
| ac_protection | MV Load switch + fuse |
| dc_protection | DC Load switch + fuse |
| enclosure_ip | TYPE 3R |
| fire_suppression | UNKNOWN |
| fire_suppression_note | Not printed. Not carried from any battery unit - a PCS skid holds no cells and its fire package, if any, would be a different design. |
| grid_monitoring | Yes |
