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.

Smaller footprint,
easy site selection

The batteries are lightweight and compact, providing greater convenience for transportation while eliminating the need for special foundation.

Higher energy density requires less footprint, so you can install in more places with greater confidence.

Pack-level safety protection

These 6 layers of protection inside each battery pack redefine system safety：
Smoke sensor, full-coverage temp. detection, aerogel insulated pads, high-temp. resistance insulated pads, a decompression valve and a fire extinguishing kit

Granular fire suppression per 12 kWh, with faster and more precise thermal runaway control than traditional fire suppression solutions.

Free of O&M

IP66 protection rating, no ingress of dust or water, no need for regular inspection and maintenance of vulnerable components.

Simple modular replacement, no more onsite spare parts to carry.

Real time system monitoring on Sigen Cloud ensures smooth operation all year round.

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*.
