| sku | UNKNOWN |
| subcategory | residential battery module, wall- or floor-mounted, parallel-scalable |
| variant_note | CONFIRMED TO EXIST - the SBS050 referenced by a previous agent is real. Architecturally it is NOT an SBR/SBH-style series stack: it is a single 5.12 kWh unit that scales by PARALLEL daisy-chain, so system voltage does NOT rise with unit count. |
Electrical
| architecture | HV as branded by Sungrow ('High Voltage LFP Battery'), but 102.4 V nominal - materially lower than SBR (128-512 V) and SBH (140.8-563.2 V). Scales in PARALLEL, not series. |
| cell_chemistry | LiFePO4 Prismatic Cell |
| current_note | Datasheet prints TWO distinct rows: 'Recommended continuous current 30 A (charge) / 50 A (discharge)' and 'Max. charging/discharging current 50 A / 50 A'. The recommended CHARGE current (30 A) is lower than the maximum (50 A) - both preserved. |
| cycle_life | UNKNOWN |
| expansion_rules | Datasheet V6: supports 1-4 modules in parallel, 20.48 kWh total (4 x 5.12 kWh). Compatibility List V4.3 SH3.0-6.0RS row: 'up to 4x SBS050 in daisy-chain'. |
| firmware_requirements | Compatibility List V4.3: 'V13 only'; 'Not compatible for SHRS V11 SN equipped with Sunclix connector'. |
