Sigenergy introduces mySigen App, a groundbreaking, self-developed application that empowers users with complete system visibility and interactive AI-driven smart features. Sigen AI emerges as the most intelligent service assistant, capable of handling various tasks such as answering questions and troubleshooting. The assistant supports both oral and written commands from the user.

Compatible with major platforms, including iOS, Android, Windows, and MacOS, Sigenergy ensures a seamless and user-friendly experience across devices, allowing convenient monitoring, management, and troubleshooting of energy generation, storage, and consumption.

  • Highest Safety Standards:

SigenStor boasts five layers of comprehensive protection measures within each battery pack, including advanced temperature sensors, an internal fire extinguisher, a decompression valve, aerogel-insulated pads, and high-temperature-resistant insulated pads. SigenStor ensures safety hazards are proactively controlled from the outset.

Sigenergy is the first to use 280 Ah battery cells with human-safe overall voltage. SigenStor operates at a maximum voltage of only 32.85V, well below the human safety voltage of 36V. This substantial decrease in risk empowers workers during installation, maintenance, and replacement procedures. Moreover, SigenStor's large cells offer an elevated number of cycles and a lifespan of up to 20 years, effectively diminishing user costs.

Partnerships with TÜV Rheinland and TÜV SÜD enhance the safety and reliability of Sigenergy's products while supporting global expansion.
