What is the Sigenergy SigenStor?
SigenStor is more than a standalone home battery. Sigenergy describes it as a 5-in-1 energy storage system, combining a solar inverter, battery PCS, battery pack, Energy Management System and EV DC charging capability. Rather than treating each part separately, the system brings generation, storage and energy use together in one connected setup.

Rollings Renewables is a trusted installation partner for Sigenergy SigenStor and other Sigenergy products. We offer exceptional service with all workmanship backed by a six-year guarantee.
Smart Energy, Built Around Your Home
SigenStor
All-in-One Energy System
With SigenStor, several parts of a typical renewable energy setup are brought together in one system. Solar generation, battery storage, energy management and EV charging can all work alongside one another without relying on multiple separate products.
For homeowners, it provides a more joined-up way to manage electricity throughout the property.
Modular Battery Storage
Energy use changes. A household that only needs battery storage today may add an electric vehicle, heat pump or more solar panels later.
SigenStor uses stackable battery modules, so storage capacity can be matched to the property's current requirements and expanded where appropriate. That makes it particularly useful for larger homes, properties with higher electricity consumption and households planning for future changes.
Energy Independence
If your solar panels generate more electricity than you're using at the time, SigenStor can store that surplus for later instead of immediately sending it back to the grid.
You can then use more of your own solar electricity in the evening or at other times when generation is lower, reducing the amount you need to draw from the grid.
Backup Power
SigenStor can also provide backup power during a grid outage when the system has been configured for this purpose.
The level of backup available will depend on the battery capacity, system design and which parts of the home you want to keep powered.
How Does the Sigenergy SigenStor Work?
SigenStor manages electricity generated by your solar panels, stores surplus power in its battery modules and makes that electricity available when your home needs it.
Its Energy Management System sits at the centre of the setup, coordinating generation, storage and consumption so the different parts of the system work together.

Make More of Your Solar Energy
Pairing SigenStor with solar panels gives you somewhere to store electricity that would otherwise be exported when your panels are producing more than your home is using.
That stored electricity can then be used later in the day, helping you increase solar self-consumption and rely less heavily on electricity from the grid. SigenStor also incorporates the solar inverter within the wider system.
Already Have Solar Panels?
Already generating your own electricity? We can look at your existing setup and advise whether SigenStor can be integrated with it, along with the most suitable configuration for your property.
Your Energy System, in the Palm of Your Hand
The mySigen app lets you see how your energy system is performing.
You can monitor solar generation, battery storage and household consumption, with energy-flow tracking showing where your electricity is coming from and where it's being used. This makes it easier to see how much of your own energy you're using and how the system behaves throughout the day.

Smarter Energy Management with AI
SigenStor isn't limited to storing electricity until you decide to use it. Sigenergy uses machine-learning technology to support energy planning and optimise how electricity moves around the system.
The system can coordinate solar generation, battery storage and household consumption based on how the property is using energy at the time.
Safety Built Into Every Layer
A home battery needs to be safe and dependable as well as efficient. SigenStor uses five layers of battery protection, long cycle-life battery cells and an IP66-rated enclosure designed to protect the equipment from dust and water.
Sigenergy also specifies 100% depth of discharge for its Sigen batteries, meaning the available battery capacity can be fully used. Together, these features help protect the battery during everyday use.
