SigenStack BC 4m Cable
Sigenergy SigenStack structure — MAIN base, SUB base, cover and controller cable — the parts a tower is built on.
SigenStack is modular by design: BAT 12.0 modules at 12.06 kWh each, seven to a tower, four to twenty-one per system, floor standing and IP66.
About the Sigenergy SigenStack structure
That modularity has a structure to it. The first tower stands on the MAIN base, which houses the battery controller and provides the earthing and connection points for the system. Each additional tower stands on a SUB base, which brings its own cable protection boxes, and is closed at the top with a stack cover.
The base is 768 × 195 × 363 mm, and a full seven-module tower with base and controller stands 2,543 mm tall at 829 kg. Check the route in and the floor before the delivery, not after it.
The 4 m controller cable is what allows the battery controller and the towers to be positioned apart from each other rather than in one rigid block.
What does this fit?
This is the base, cover and controller cable a SigenStack tower is assembled on.
A SigenStack system is towers of BAT 12.0 modules, seven to a tower and up to twenty-one per system. The first tower stands on a MAIN base and carries the battery controller; every tower after it stands on a SUB base and is finished with a stack cover.

What the job needs
The details that decide whether this suits the system:
- One MAIN base per system: it holds the battery controller. One SUB base and one cover for every additional tower.
- Seven modules to a tower, four to twenty-one per system, 253 kWh maximum.
- The SUB base includes cable protection boxes.
- Base dimensions are 768 × 195 × 363 mm. A four-module tower is 1,643 mm tall and 508 kg; a seven-module tower is 2,543 mm and 829 kg, both including the base and the controller.
- The 4 m controller cable set contains 2 × power cable, 1 × PE cable, 1 × signal cable, 7 × DT terminals and 1 × signal connector.
- System is floor standing, IP66, smart air cooled, under 70 dB, −20 °C to +55 °C, with aerosol fire suppression, a smoke sensor and an exhaust system.
Where this earns its place
These are the parts a SigenStack tower is built from.
Sigenergy BC 4 m Cable technical data
Questions we get asked about this inverter
What is the difference between the MAIN and SUB bases?
The MAIN base is the foundation of the first tower and houses the battery controller. A SUB base supports each additional tower and includes cable protection boxes.
Do I need a cover for every tower?
Each additional tower is finished with a stack cover. The first tower is closed by the battery controller that sits on the MAIN base.
How many modules go on one base?
Seven. Twenty-one is the system maximum, so three towers.
What is in the 4 m cable set?
Two power cables, a PE cable, a signal cable, seven DT terminals and a signal connector.
