The BDU (Battery Disconnect Unit) manages the connection between battery modules and the inverter, providing protection, communication and system balancing. The Base forms the stable foundation on which the battery modules are stacked. The system supports \u003cstrong\u003e3 to 15 battery modules in series\u003c\/strong\u003e per cluster, resulting in a system voltage of 134 to 876 V. Up to \u003cstrong\u003e12 clusters\u003c\/strong\u003e can be connected in parallel. Communication with the inverter is via \u003cstrong\u003eCAN or RS485\u003c\/strong\u003e (RJ45 connector).\n  \u003c\/p\u003e\n\n  \u003cul class=\"usp-list\"\u003e\n    \u003cli\u003e\u003cstrong\u003eScalable system:\u003c\/strong\u003e supports 3–15 Stack 280 battery modules in series per cluster, up to 12 clusters in parallel.\u003c\/li\u003e\n    \u003cli\u003e\u003cstrong\u003eWide inverter compatibility:\u003c\/strong\u003e CAN\/RS485 communication (RJ45) with GoodWe, Solis, Growatt, Deye, SINENG and more.\u003c\/li\u003e\n    \u003cli\u003e\u003cstrong\u003eIntegrated fire protection:\u003c\/strong\u003e built-in aerosol fire extinguisher for maximum safety.\u003c\/li\u003e\n    \u003cli\u003e\u003cstrong\u003eRobust construction:\u003c\/strong\u003e IP20 protection, forced air cooling, suitable for indoor installation.\u003c\/li\u003e\n    \u003cli\u003e\u003cstrong\u003eCertified:\u003c\/strong\u003e CE, EMC and UN38.3 certified for professional installation and operation.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch2\u003eTechnical notes for installers\u003c\/h2\u003e\n  \u003cp class=\"p4\"\u003e\n    The BDU \u0026 Base is suitable for indoor use only (\u003cstrong\u003eIP20\u003c\/strong\u003e). The BDU has dimensions of \u003cstrong\u003e770 × 425 × 230 mm\u003c\/strong\u003e and the Base \u003cstrong\u003e770 × 425 × 133 mm\u003c\/strong\u003e; the combined weight of BDU \u0026 Base is \u003cstrong\u003e±56 kg\u003c\/strong\u003e. A full column of 8 modules + BDU reaches a height of approximately 2208 mm; a minimum clearance of \u003cstrong\u003e450 mm\u003c\/strong\u003e above the system is required (floor to ceiling ≥ 2658 mm). More than 8 modules must be split across two columns. Grounding resistance must be \u003cstrong\u003e≤100 mΩ\u003c\/strong\u003e. Use the supplied CAN resistor (120 Ω) on the appropriate ports in parallel systems. Consult the compatibility list for the correct communication settings per inverter type.\n  \u003c\/p\u003e\n\n  \u003cdiv class=\"alert-box\"\u003e\n    \u003cstrong\u003eNote:\u003c\/strong\u003e This package contains only the BDU \u0026 Base (control unit, Package A). Battery modules (Dyness Stack 280 HV Battery Module, Package B) are sold separately. A minimum of 3 battery modules is required for a functional system.

The system is suitable for indoor use only (IP20). The combined weight of BDU \u0026 Base is ±56 kg. A full column of 8 modules + BDU (height ±2208 mm) requires a minimum clearance of 450 mm above the system (floor to ceiling ≥ 2658 mm). More than 8 modules must be split across two columns. Grounding resistance ≤100 mΩ. Use the supplied CAN resistor (120 Ω) on the appropriate ports in parallel systems. If installing on an upper floor, a professional assessment of the floor's load-bearing capacity is required.\u003c\/p\u003e\n        \u003c\/div\u003e\n      \u003c\/div\u003e\n    \u003c\/details\u003e\n\n  \u003c\/div\u003e\n\n  \u003cp class=\"p4\"\u003e\n    View more products in our \u003ca href=\"https:\/\/www.shop-rebor.com\/en\/collections\/dyness-storage\" title=\"Dyness Storage\"\u003eDyness Storage collection\u003c\/a\u003e.\n  \u003c\/p\u003e\n\n\u003c\/div\u003e\n","brand":"Dyness","offers":[{"title":"Default Title","offer_id":53541711020359,"sku":"STACK280-BDU","price":935.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0882\/5641\/4023\/files\/Dyness-Stack280-bdu-base-complete.webp?v=1776186221","url":"https:\/\/www.shop-rebor.com\/en\/products\/dyness-stack-280-bdu-base-besturingseenheid","provider":"Rebor B.V.","version":"1.0","type":"link"}
