Sigenergy SigenStack Base SUB-0.5C

Sigenergy SigenStack Base SUB-0.5C is a floor-standing battery controller/base for the SigenStack C&I energy storage system. It is used with the Sigen C&I Hybrid Inverter Series and supports PV + ESS DC-coupled projects when the BST model is specified.

Key Features
Floor-standing modular base

Supports stackable installation within the SigenStack system architecture.

System ingress protection IP66

Provides protected installation suitability where a sealed enclosure rating is required.

Wide operating voltage range

Operates across 550 to 1100 V for SigenStack system integration.

High current interface

Rated at 180 A maximum input and output current to inverter.

Integrated safety functions

Includes pack-level safety protection, thermal runaway control, and aerosol, smoke sensor and exhausting fire suppression system.

Benefits
  • Floor-standing, stackable format simplifies system layout.
  • IP66 rating supports exposed installation environments.
  • High-voltage operating range and 180 A current rating support system integration.
  • Built-in safety and fire suppression functions add system protection at pack level.
Technical Summary

Sigenergy SigenStack Base SUB-0.5C for the SigenStack C&I energy storage range. Model M2-0.5C-BST. Floor-standing base/controller with CAN communication, 550 to 1100 V operating voltage range, 180 A maximum input/output current to inverter, 60 kg weight, and 770 x 248 x 363 mm dimensions. System ingress protection IP66. Operating temperature range -20 to 55 °C. Maximum operating altitude 4,000 m with derating at 2,000 m.

Installation Notes

Installation method: floor standing. Base dimensions: 770 x 195 x 363 mm. For systems with 19 battery modules or fewer, and for PV + ESS (DC coupling) projects, the battery controller should use the BST model.

Efficiency

SigenStack battery modules are specified with 0.5C nominal charge/discharge rate and 1C maximum charge/discharge rate. Range notes also state higher energy density and reduced footprint.
