Sigenergy introduced SigenStor Neo, an all-in-one residential system integrating PV inverter, battery, and energy management into a single platform
The system incorporates backup functionality, including 63 A switching, zero-ms switchover, and support for hybrid operation scenarios
Design updates focus on installation standardization and thermal management to improve deployment consistency and long-term performance
With growing adoption of residential energy systems, installation efficiency and system reliability are becoming key priorities for storage solutions. Manufacturers are increasingly focusing on integrated platforms that simplify deployment while maintaining performance.
China-based energy storage manufacturer Sigenergy introduced new residential storage solutions during the launch of its Nantong Smart Energy Center. Speaking at the event, Roy Zhang, President of Global Sales and Service at Sigenergy, detailed the company’s focus on integrated system design and lifecycle reliability, along with the role of AI-driven capabilities in improving system coordination and performance.
Part of the new product introductions was SigenStor Neo, an all-in-one system that focuses on installation, safety, and thermal performance for residential applications. The system integrates a PV inverter, battery PCS, energy management system, gateway, and battery into a single platform. It supports single-phase configurations from 2.5 kW to 12 kW and 3-phase systems from 3 kW to 15 kW, with battery options of 6 kWh and 8 kWh.
Installation is a major bottleneck in residential storage deployments, particularly as projects scale across different installers and site conditions. Addressing this, Sigenergy has focused on simplifying on-site work through design changes such as angled ports at the inverter terminals, which make it easier to handle larger 16 mm² cables in space-constrained environments, according to Zhang. The system also supports standard electrical tools, reducing dependency on specialized equipment. In addition, a software-based cabling modeling tool helps standardize wiring and improve installation consistency across projects. Improved terminal visibility further supports verification during installation, reducing the likelihood of connection errors and rework.
Reliability during operation has been addressed through integrated safety and backup features. Temperature monitoring is implemented using NTC sensors at terminal points, enabling real-time detection and automatic shutdown in the event of overheating. The inverter integrates a 63 A backup switch, removing the need for an external gateway in most scenarios. It supports zero-millisecond switchover and can handle up to 200% load for 10 seconds, which, according to the company, helps maintain stable operation during grid outages. Direct connection to diesel generators is also supported, allowing operation across grid-tied, off-grid, and hybrid microgrid environments.
The company says it has also improved battery performance and thermal management with this product. The SigenStor Neo design supports a 0.8 C charging rate, enabling faster charging under high-load conditions. This is achieved through a cell suspension architecture that physically separates battery cells from the PCB to improve heat dissipation. The system incorporates integrated thermal management within the enclosure, improving heat dissipation and supporting stable operation under high load conditions and long-term battery performance.
Beyond residential systems, the company also introduced SigenTerra, a utility-scale storage platform with grid-forming capability. The system is designed as an all-in-one solution for grid applications, supporting stable operation in increasingly complex energy systems.
Sigenergy continues to offer microinverters and plans to introduce SigenMate, a balcony PV solution for residential applications in Europe. It also continues to offer its existing SigenStor EC platform, with both product lines set to evolve in parallel. Across its portfolio, the company highlighted lifecycle reliability as a key design focus, with systems intended to operate for 10 to 20 years.
During the event, Zhang also introduced the company’s new utility-scale inverter platform, which marks Sigenergy’s entry into the high-power PV segment, along with a C&I inverter offering (see Sigenergy Enters Utility-Scale PV With New Inverter Platform).
