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\u0026amp;I Hybrid Inverter series minimise installation time on site.\n  \u003c\/p\u003e\n\n  \u003cul class=\"feat-list\"\u003e\n    \u003cli\u003eMAIN base — required in every SigenStack installation; houses primary power and communications\u003c\/li\u003e\n    \u003cli\u003eSupports up to 5 SigenStack 0.5C battery modules per stack\u003c\/li\u003e\n    \u003cli\u003eIP66 rated — fully sealed against dust and water; suitable for indoor and outdoor deployment\u003c\/li\u003e\n    \u003cli\u003eBuilt-in aerosol fire suppression — pack-level safety protection\u003c\/li\u003e\n    \u003cli\u003eSmart air cooling compatibility — optimises thermal performance and extends battery cycle life\u003c\/li\u003e\n    \u003cli\u003eCompact footprint (770 × 363 × 195 mm) — efficient use of plant room space\u003c\/li\u003e\n    \u003cli\u003eTool-free assembly — reduces on-site installation time significantly\u003c\/li\u003e\n    \u003cli\u003ePlug-and-play CAN integration — seamless connection to Sigen C\u0026amp;I Hybrid Inverter Series\u003c\/li\u003e\n    \u003cli\u003eCorrosion-resistant materials — designed for long-term indoor and outdoor deployment\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003cdiv class=\"callout callout-blue\"\u003e\n    ℹ️ \u003cstrong\u003eMAIN vs SUB base units:\u003c\/strong\u003e Every SigenStack stack starts with one MAIN base unit. If more than five battery modules are required, additional SUB base units (SIG-STACK-BASE-SUB-0.5C) extend the stack — each SUB also supports up to five modules.
