About This Product

The Sigenergy SigenStack Battery Main Base (1C) is the main floor base used at the bottom of a SigenStack 1C battery stack. It provides the physical foundation for the stacked battery modules and forms part of the connection path between the battery stack, battery controller and compatible Sigenergy C&I hybrid inverter system.

This main base is intended for SigenStack 1C battery configurations, where higher charge and discharge capability is required compared with lower C-rate stack options. It is used with SigenStack BAT 12.0 battery modules and the matching Sigenergy battery controller in commercial and industrial energy storage systems.

Who This Product Suits

The Sigenergy SigenStack Battery Main Base (1C) suits installers building a Sigenergy SigenStack 1C battery system for commercial or industrial solar storage projects. It is the correct choice when the design calls for a main battery stack rather than an expansion-only sub stack.

It is best suited to sites that need a modular battery system with fast charge and discharge capability, such as businesses wanting to increase solar self-consumption, support peak-load management or add larger-scale energy storage to a Sigenergy C&I inverter installation.

Specifications Explained

The Sigenergy SigenStack Battery Main Base (1C) is designed for SigenStack 1C battery stacks using SigenStack BAT 12.0 modules. The 1C rating refers to the higher charge and discharge class of the compatible stack, allowing the battery system to move energy more quickly when paired with the correct controller and inverter setup.

As the main base, it is used at the bottom of the primary stack and works with the Sigenergy battery controller. Sigenergy documentation shows SigenStack systems are modular, with multiple battery modules per stack and multiple modules per inverter depending on the approved system configuration. The SigenStack platform also uses integrated power and communication connections, IP66-rated equipment design and battery-level protection features within the overall system.

Summary

The Sigenergy SigenStack Battery Main Base (1C) is a required base component for building a main SigenStack 1C battery stack. It is not a standalone battery or inverter; it is the structural and connection base used as part of a complete Sigenergy C&I energy storage system.

For installers, the key point is compatibility: use this base where the system design specifies a SigenStack MAIN-1C base with matching SigenStack BAT 12.0 modules, the correct Sigenergy battery controller and a compatible Sigenergy C&I hybrid inverter.
