Sigenergy SigenStack BC Cables 4m | 11180009 | DC Power Link

Description

The Sigenergy SigenStack BC Cables 4m is the manufacturer-specified DC power cable set that links the SigenStack Battery Controller (BC / BC-BST) to the Sigen C&I Hybrid Inverter, carrying the high-voltage BAT+/BAT- connection at the heart of every SigenStack commercial and industrial energy storage installation. Supplied at a fixed 4-metre length, it is the correct-spec accessory to order whenever a SigenStack battery system is being paired with a Sigen Hybrid or PV inverter and the standard cable run needs extending beyond the base unit.

Because SigenStack is a modular, rack-based system, getting the BC-to-inverter power link right is not optional — it is the single connection that carries the full charge/discharge current of the entire battery stack. Using the manufacturer's own cable set, rather than a generic equivalent, keeps the run within Sigenergy's tested current and voltage tolerances and preserves the system's IP66-rated, plug-and-play design intent.

Compatibility note: This cable set connects the SigenStack Battery Controller to a compatible Sigen C&I Hybrid Inverter. It is only required where an inverter's energy storage port is being configured with a SigenStack battery system — confirm your BC model (BC, BC-BST) and inverter series before ordering to ensure the correct connection is being made.

Installation note: DC power connections of this kind carry the full battery stack current and voltage. Installation must be carried out by a trained or qualified electrical engineer, following the SigenStack Energy Storage System Installation Guide, with the inverter and connected equipment fully isolated and de-energised before any wiring work begins.

Manufacturer-Specified Fit

Genuine Sigenergy cable set engineered specifically for the SigenStack platform, ensuring correct connector fit and rated current handling for the BC-to-inverter link.

4-Metre Reach

Fixed 400 cm length gives installers flexibility to route the BC-to-inverter connection where cabinet spacing or wall-mounted inverter positioning demands extra distance.

BAT+/BAT- Power Link

Carries the primary high-voltage DC connection between the SigenStack Battery Controller and the Sigen Hybrid Inverter's dedicated SigenStack DC cable interface.

Plug-and-Play Compatibility

Designed to integrate directly with the SigenStack modular platform, supporting the system's tool-free, rack-based installation approach.

C&I-Grade Build

Built to support the demands of commercial and industrial energy storage systems, where the BC-to-inverter link carries substantial charge/discharge current.

Straightforward Stocking Item

A single-purpose accessory cable — no configuration or programming required, simple to specify alongside a SigenStack battery order.

What does the SigenStack BC Cables 4m actually connect?

It provides the DC power connection between the SigenStack Battery Controller (BC or BC-BST) and the Sigen C&I Hybrid Inverter's SigenStack DC cable interface (BAT+/BAT-), carrying the battery stack's full charge/discharge current to the inverter.

Do I need this cable with every SigenStack order?

Only if your inverter's energy storage port is being configured with a SigenStack battery system and the standard connection needs to run this distance. Confirm the required cable length against your installation layout before ordering.

Can I substitute a generic DC cable instead?

No — this connection carries the full battery stack current at high voltage. The manufacturer-specified cable is engineered to Sigenergy's tested current and voltage tolerances for this exact connector interface, and substituting an unverified cable risks both performance and warranty cover.

Who should install this cable?

A trained or qualified electrical engineer familiar with the SigenStack Energy Storage System Installation Guide. The inverter and all connected equipment must be fully isolated before any wiring work begins.
