SigenStor System Review

As battery system technology continues to improve, new products are making their way into the Australian market. One of these brands is Sigenergy.

Sigenergy, particularly its SigenStor system, is gaining traction as a potentially game-changing all-in-one solar inverter, battery, and EV charger, praised for its modularity, safety features, and EV integration.

Sigenergy can be installed both On-grid and Off-grid, is modular, and is sensibly priced, making this product very attractive to both installer and end user.

Here's a more detailed look at Sigenergy and its SigenStor system:

Key Features and Benefits

All-in-One Design
The SigenStor combines a solar inverter, battery, and EV charger into a single unit, simplifying installation and potentially reducing costs.

Modularity and Scalability
The system is designed to be modular, allowing users to expand their battery capacity as needed by adding more battery modules.

Safety Features
Sigenergy emphasises safety, incorporating features like insulated pads, internal fire extinguishers, and multiple temperature sensors.

EV Charging Integration
The SigenStor includes a built-in DC 25kW EV charger, enabling homeowners to charge their electric vehicles efficiently.

Software-First Approach
Sigenergy's design philosophy prioritises software, allowing for easier updates and future-proofing of the system.

Independent Battery Modules
Each battery module operates independently, meaning that if one module fails, the others are not affected, and new batteries can be added to existing systems without performance degradation.

Three-Phase Inverter Option
The SigenStor offers a three-phase inverter option for better power balancing and true three-phase backup.

V2H/V2G Capability
The system is designed for Vehicle-to-Home (V2H) and Vehicle-to-Grid (V2G) functionality, allowing users to use their EV battery to power their home or even feed energy back into the grid.

Potential Drawbacks and Considerations

New Company
Sigenergy is a relatively new company, and some installers may be hesitant to recommend them due to a lack of a long track record.

Wall Mounting Limitations
For wall-mounted systems, Sigenergy recommends not having more than two modules, and the energy controller on the wall mount is not strong enough to take the full system.

Overall

The Sigenergy SigenStor system appears to be a promising option for homeowners looking for a flexible, safe, and feature-rich solar and energy storage solution, particularly those with EVs. Its modular design, advanced safety features, and EV integration capabilities could make it a compelling choice for those looking to maximise their solar system's potential and reduce their reliance on the grid.
