Sigenergy SigenStack MAIN Base Unit 0.5C | C&I Battery Foundation

The SigenStack MAIN Base Unit 0.5C is the foundation and control hub for a SigenStack commercial and industrial battery stack. Every SigenStack installation requires exactly one MAIN base unit; it houses the primary power and communication connections, integrates with the Battery Controller (BC) above it, and supports a stack of up to five SigenStack 0.5C battery modules. The compact footprint (770 × 363 × 195 mm) allows deployment in constrained plant rooms and commercial spaces, while the IP66 enclosure ensures full protection against dust and water for both indoor and outdoor use. A built-in aerosol fire suppression system and smart air cooling compatibility provide the safety and thermal management needed for high-capacity commercial energy storage. Tool-free assembly and plug-and-play integration with the Sigen C&I Hybrid Inverter series minimise installation time on site.
