Sigenergy SigenStack SUB Base Unit 0.5C | Stack Expansion C&I Battery
The SigenStack SUB Base Unit 0.5C is the expansion base used to extend a SigenStack installation beyond the initial five-module capacity of a MAIN base. When a project requires more than five SigenStack battery modules, one or more SUB base units are added alongside the MAIN — each accepting up to five further modules. Like the MAIN base, the SUB unit shares identical compact dimensions (770 × 363 × 195 mm), IP66 protection, built-in aerosol fire suppression, and smart air cooling compatibility. All connections are plug-and-play, maintaining the SigenStack system's fast commissioning workflow. The SUB base does not replace the MAIN; one MAIN base unit is always required as the primary stack foundation.
- Expansion base — adds capacity beyond the 5-module limit of a single MAIN base unit
- Each SUB supports up to 5 additional SigenStack 0.5C battery modules
- Identical form factor to MAIN base — same dimensions, same installation workflow
- IP66 rated — fully sealed against dust and water
- Built-in aerosol fire suppression — pack-level safety consistent across the stack
- Smart air cooling compatible — maintains thermal management across expanded stacks
- Tool-free plug-and-play connections — fast addition to existing or new SigenStack systems
- Compact footprint (770 × 363 × 195 mm) — minimal additional floor space per 5-module expansion
