| hardware_revision | UNKNOWN |
| legacy_name | UNKNOWN |
| manufacturer | Sungrow |
| market_version | US datasheet V15 (2022) |
| model | ST2752UX-US |
| product_family | PowerTitan (1.0) |
| product_status | active |
| product_status_evidence | Live US product page (powertitan-st2236ux-us-st2752ux-us) as of 2026-09-03; datasheet V15 dated 2022 |
| region | North America (60 Hz, UL 9540 / NFPA 855) |
| release_year | UNKNOWN |
| sku | UNKNOWN |
| subcategory | utility-scale liquid-cooled DC battery container (external PCS required) |
| variant_note | Sibling ST2236UX-US shares the product page but NO datasheet for it was located or fetched - see _coverage. |
Electrical
| architecture | DC battery container, 1500 V class; requires an external PCS |
| battery_rack_configuration | UNKNOWN |
| cell_chemistry | LFP |
| cell_spec | UNKNOWN |
| cycle_life | UNKNOWN |
| energy_note | Datasheet row reads 'Battery capacity (BOL): 2752 kWh' - BOL = beginning of life, an important qualifier preserved verbatim. |
| expansion_rules | UNKNOWN |
| firmware_requirements | UNKNOWN |
| grid_services | N/A at this unit - provided by the external PCS |
| max_charge_power_kw | UNKNOWN |
| max_discharge_power_kw | UNKNOWN |

| mixed_generation_restrictions | UNKNOWN |
| modules_max | UNKNOWN |
| modules_min | UNKNOWN |
| nominal_energy_kwh | 2752 |
| nominal_voltage_v | UNKNOWN |
| operating_voltage_max_v | 1500 |
| operating_voltage_min_v | 1160 |
| pcs_topology | None - external PCS (SC5000UD-MV-US) required |
| rated_ac_power_kw | UNKNOWN |
| rated_ac_power_note | THIS UNIT HAS NO AC RATING OF ITS OWN. It does not convert. The AC figures on the datasheet belong to the separate SC5000UD-MV-US PCS: 'Transformer rated power 5,000 kVA', 'LV/MV voltage 0.9 kV / 34.5 kV', 'Nominal grid frequency 60 Hz', 'Power factor > 0.99 (at nominal power)'. They are recorded in documented_relationships against that PCS, NOT as this product's ratings. |
| rated_power_kw | UNKNOWN |
| round_trip_efficiency_pct | UNKNOWN |
| scaling_architecture | Datasheet documents system-level AC capacities of '10,379 kWh (2-hour config)' and '21,448 kWh (4-hour config)' behind one 5,000 kVA transformer - i.e. multiple battery units per PCS skid. The exact unit count per skid is not printed. |
| supported_installation_topology | DC-coupled to an SC5000UD-MV-US MV PCS skid; multiple battery units per skid |
| system_energy_kwh | 2752 |
| usable_dod_pct | UNKNOWN |
| usable_energy_kwh | UNKNOWN |
| voltage_note | 'Battery voltage range: 1160 ~ 1500 V' |
Physical / mechanical
| cooling | Liquid cooling |
| cooling_note | 'Cooling concept of battery chamber: Liquid cooling' |
| corrosion_grade | UNKNOWN |
| depth_mm | 1730 |
| dimensions_note | 'Dimensions of battery unit (W * H * D): 9340*2600*1730mm' - note the row is explicitly scoped to the BATTERY UNIT. |
| enclosure_rating | IP 54/Type 3R |
| height_mm | 2600 |
| ip_rating | IP 54 / Type 3R |
| mounting | Containerised, outdoor |
| weight_kg | 26400 |
| weight_note | 'Weight of battery unit: 26,400kg' - again explicitly the battery unit only, excluding the PCS skid. |
| width_mm | 9340 |
Installation
| indoor_outdoor | Outdoor |
| mounting_method | Container on foundation |
| supported_installation_topology | Paired with external SC5000UD-MV-US PCS |
Environment
| charge_temperature_c | UNKNOWN |
| discharge_temperature_c | UNKNOWN |
| humidity | 0 ~ 95 % (non-condensing) |
| humidity_note | NON-CONDENSING and capped at 95% - notably tighter than PowerTitan 2.0/3.0, which both print '0 % ~ 100 %'. |
| indoor_outdoor | Outdoor |
| max_altitude_m | 3000 |
| noise | UNKNOWN |
| operating_temperature_c | -30 to 50 ( > 45 derating ) |
| storage_temperature_c | UNKNOWN |

| ports | UNKNOWN |
| rs485 | UNKNOWN |
Protection
| enclosure_ip | IP 54 / Type 3R |
| fire_suppression | Fused sprinkler heads, NFPA 69 explosion prevention |
| fire_suppression_note | WATER-BASED sprinkler suppression plus NFPA 69 explosion prevention - a different approach from PowerTitan 2.0's NFPA 68 venting-and-detection package. |
Certifications
| listed | ['UL 9540', 'UL 9540A / NFPA 855'] |
