AC Board - Sigenergy HYB Bypass DB - Single 

SKUs: ACB-SHB11 & ACB-SHB12

The AC Board Sigenergy HYB Bypass Distribution Board is a premium, heavy-duty solution engineered specifically for single hybrid inverter installations. Housed in a robust, powder-coated mild steel enclosure, this board features dedicated Molded Case Circuit Breakers (MCCBs) for both grid and backup inverter ports to ensure absolute system control and overload protection. It incorporates a specialized bypass switch configuration with pre-wired auxiliary terminals to signal the inverter's IO ports seamlessly. Built for ultimate regulatory compliance and electrical safety, the distribution board features a dual-neutral bar layout that bridges automatically during bypass , allowing the system to use the main switchboard's MEN link safely while preserving correct earthing networks during backup mode. Fully factory-tested, pre-labelled, and designed with built-in DIN expansion space , this board slashes field integration times while minimizing complex wiring errors on-site.

Key Features AC Board - Sigenergy HYB Bypass DB - Single:

• Dedicated Dual-Port MCCBs: Outfitted with robust MCCBs assigned to protect and isolate both the grid and backup ports of the hybrid inverter.

• Advanced Dual-Neutral Earthing: Utilizes separate grid-side and backup-side neutral bars that link when the bypass closes, preserving correct earthing compliance.

• Pre-Wired Auxiliary Bypass Switching: Features two dry-contact auxiliary switch lines terminating in $2.5\text{ mm}^2$ terminals for direct, foolproof inverter IO mapping.

• Spare Fused DIN Expansion: Includes a spare DIN rail section paired with a 32A HRC control supply fuse, allowing rapid installation of monitoring equipment.

• Ultra-Spacious High-Torque Chassis: Built with heavy-duty spreader tags to comfortably handle large dual-lugged inverter cable links.

• Maximum Mechanical Resilience: Encased in a powder-coated grey IP66 and IK10-rated steel cabinet featuring a lockable outer door and an IP2X touch-safe inner door shield.

• Pre-Labelled & Factory Compliant: Arrives fully factory-tested according to strict standards and complete with premium labeling for the rest of the job site.
