SigenStack
Innovative modular BESS with unparalleled safety precision and cost-effectiveness
Modular Design &
stackable installation
12 kWh per module, flexible deployment, precisely meeting project needs to cut investment and redundancy.
Easier installation, no need for cranes or other special installation equipment. Stack and play with no complex wiring between modules.
Automatic device networking enables ultra-fast commissioning of the entire system.
Less footprint,
lower noise operation
Higher energy density requires less footprint, so you can install in more places with greater confidence.
Smart Air Cooling technology dynamically controls fan speed based on operating environments to achieve lower noise operation than traditional solutions.

Pack-level Safety
Protection
Granular fire suppression per 12 kWh, with faster and more precise thermal runaway control than traditional fire suppression solutions.
Innovative DC Coupling
Lower CAPEX, free from PV inverter, extra AC combiner or MV station, etc. A simpler system with fewer devices and points of failure always leads to higher availability.
As a DC-coupled solution, SigenStack improves round-trip efficiency by up to 2% compared to traditional AC-coupled solutions where energy is lost due to AC/DC conversion and extra cables*.
