Why Sigenergy?
Sigenergy's product range offers many benefits for homeowners with its innovative technology and smart use.
1. Spend less on electricity
A Sigenergy system can help you buy less electricity from the grid and make better use of cheaper rates when you do need it. Your solar powers the home first, while surplus electricity can be stored for later. Sigen AI Mode can also use your consumption, weather forecasts and electricity prices to decide when to charge or use the battery. Your actual savings will depend on your usage, system and tariff.
2. Use more of your own solar
A battery means more of the electricity your panels generate can stay useful after the sun goes down. Sigenergy can store surplus solar during the day and use it later, helping your home rely more on its own generation and less on electricity imported from the grid.
3. Keep energy management simple
You shouldn't have to keep deciding when to charge the battery or when to use stored electricity. Sigenergy brings the inverter, battery and energy management together in one system, while Sigen AI Mode can handle many of those routine decisions automatically. You get the benefits of a more advanced setup without having to manage it throughout the day.
4. Stay informed and in control
Automation doesn't mean giving up control. The mySigen app lets you see your solar generation, household use, battery level, and grid imports and exports in one place. You can leave the system to manage energy automatically or adjust operating modes and schedules when you want more say over what it does.
5. Adapt as your needs change
Your electricity needs may grow if you add an EV, heat pump or simply use more power at home. SigenStor's modular design gives you scope to add compatible battery capacity later rather than treating your first setup as fixed forever. How far you can expand depends on the controller, battery models and overall system design.
6. Gain greater energy security
Stored solar can keep supplying your home after daytime generation falls, reducing how much you need from the grid at that moment. With the right Sigen Energy Gateway and system design, it can also provide backup power during an outage. Backup isn't included automatically, so the exact circuits and capacity available will depend on the installed setup.
7. A reliable choice of brand
Solar and batteries are long-term purchases, so the company behind the equipment matters. Sigenergy was founded in 2022 but has grown quickly, reporting more than 25,000 registered installers across over 120 countries and regions by September 2026. UK wholesaler Segen also lists it among its key battery manufacturers, while SigenStor batteries and Energy Controllers carry 10-year manufacturer warranties.
The Sigenergy System
Alongside your solar panels, a Sigenergy setup can include three main pieces of equipment:
Sigen Energy Controller
The inverter that converts your panels' electricity into a form your home can use, and coordinates the rest of the system.
SigenStor battery
Stores surplus solar for use later in the day or evening.
Sigen Energy Gateway
Optional equipment that keeps chosen circuits running during a power cut.
The Sigen Energy Controller
The centrepiece of your solar and battery system, managing how the electricity your panels generate is converted and used.
Make better use of a complicated roof
Depending on the model, Energy Controllers use two to four independent MPPTs, allowing separate groups of panels to be managed independently. That can be useful when panels sit on different roof pitches or face different directions.
Keep more of the solar you generate
Current models reach maximum conversion efficiencies of roughly 97.6% to 98.4%, depending on the model and phase. That means relatively little of the electricity generated by your panels is lost during conversion.
Give your solar array more room to work
Suitable single-phase Energy Controllers can accept more panel capacity than their rated AC output, giving your installer more flexibility when designing the array around your roof and expected generation. This does not mean the inverter can output more than its rated power at any one time.
Keep solar and battery working together
The Energy Controller is designed as part of the SigenStor system, with energy management built in and a direct connection to compatible battery modules. This lets solar generation, battery storage and household demand work through the same system.
Protected and backed long-term
Energy Controllers include protections against issues such as overcurrent, surges and electrical faults, while the IP66-rated enclosure helps protect against dust and water. Current European models also come with a 10-year limited manufacturer product warranty, subject to its terms.

The SigenStor Battery
SigenStor stores electricity from your solar panels so you can use it later, with a modular design that gives you flexibility over how much storage you have.
Add more storage as your needs grow
SigenStor can use multiple compatible battery modules, so you can increase capacity later if your electricity use changes. Module-level optimisation also allows compatible batteries of different ages and states of health to work together, subject to the controller, battery models and system design.
Make good use of the capacity you buy
SigenStor batteries provide a high level of usable capacity and allow 100% depth of discharge of that usable capacity. In practical terms, most of the storage capacity stated as usable is available for your home rather than being held back as an inaccessible buffer.
Get useful power when your home needs it
SigenStor is designed to deliver stored electricity at meaningful power levels, not simply hold it. Available power can also increase as compatible modules are added, although the amount your home can draw will depend on the controller and overall system design.
Store energy with confidence
SigenStor uses LFP battery chemistry, with individual module management, built-in protection and an IP66-rated enclosure. These features are designed to support safe, reliable operation, although the battery still needs to be installed in a suitable location.
How Sigenergy Makes Solar
Easier to Live With
Less effort
Sigen AI Mode can handle the routine decisions, charging when electricity is cheap and drawing on stored or solar power when it isn't, based on your usage, the weather and current prices.
Less confusion
The mySigen app puts solar generation, battery activity, and grid import and export in one place, so you can see what your system is doing without piecing it together yourself.
More resilience
Add the Sigen Energy Gateway and an appropriately designed system can keep selected circuits, or the whole home, running through a power cut. This is optional equipment, not something every system includes, so check what your package covers.
Easier electrification
Sigenergy's EV charger can put surplus solar into your car first and schedule charging around cheaper electricity periods, bringing your car into the same energy system as your home rather than treating it separately.

Property type doesn't rule it out either. Tenement flats, Victorian terraces and modern new builds can all be assessed for a Sigenergy system, with your installer confirming what fits during the property assessment.
Sigenergy FAQs
Still have questions? Here are our most-asked questions about Sigenergy, answered.
How much SigenStor battery storage do I need?
It depends on how much electricity you use, when you use it, and how much surplus your panels are likely to generate. A household that uses most of its electricity during the day needs less storage than one that uses more in the evening. SigenStor's modular design means you don't have to get this exactly right the first time. Your installer will size the system around your actual usage and can build in room to expand.
Does Sigenergy work with smart electricity tariffs?
Yes. Sigenergy's system is designed to make use of time-of-use pricing, charging when electricity is cheaper and drawing on stored energy when it isn't. Octopus's Charge Pack service currently lists Sigenergy as a compatible battery, though tariff compatibility can change, so it's worth checking directly with your supplier before you commit.
Will a Sigenergy battery keep my home powered during a power cut?
It can, but only with the right Sigen Energy Gateway and a system designed for backup. A SigenStor battery on its own doesn't automatically give you this. How long the power lasts depends on your battery's charge, your usage and which circuits are set up for backup, so ask your installer exactly what's covered in your package.
What warranty comes with Sigenergy equipment?
The Energy Controller and SigenStor battery each carry a 10-year manufacturer warranty. An optional five-year extension is available, taking total cover to 15 years if purchased and activated within 12 months of installation. Other components, such as the Energy Gateway, carry shorter warranty periods, so ask your installer for the specifics of your package.
Can I add more battery capacity later?
Yes, up to the limits of your installed controller. SigenStor supports up to six battery modules on one controller, and each module has its own optimiser, so newer and older batteries can work together rather than the whole stack being limited by the oldest unit. This is useful if you get an EV or heat pump after your initial installation.
Can I control it myself, or does the AI manage everything?
Both. Sigen AI Mode can automate the day-to-day decisions, but the mySigen app also lets you set your own schedules and adjust how the battery charges and discharges. You can hand over as much or as little control as you want.
How long should a SigenStor battery last?
There's no exact number that applies to every household, since battery ageing depends on temperature, usage and charging patterns. Sigenergy's current cells are rated for 10,000 cycles under lab test conditions, and every battery carries a 10-year manufacturer warranty guaranteeing at least 60% of its usable capacity over that period.
Can Sigenergy work with my EV or a future heat pump?
Yes. An existing EV charger or heat pump can run alongside a Sigenergy system as a normal household load, benefiting from your solar generation the same way any appliance does. Sigenergy's own EV charger goes further, putting surplus solar toward your car first and scheduling charging around cheaper electricity. If you're planning to add either in future, tell your installer so the system can be sized with that demand in mind.
How does Sigenergy compare to other home battery systems?
Sigenergy's main strengths are its modular battery expansion, the way its inverter, battery and app work as one system, and its AI-driven energy management. Warranty terms are broadly competitive with rivals like Tesla and GivEnergy, though the details differ between manufacturers.
Worth noting: in April 2026, a UK safety review flagged a connector issue that could cause overheating on certain single-phase Energy Controllers installed before February 2026. Sigenergy ran an inspection and update programme, and systems installed since are unaffected.
For most Edinburgh homeowners, the right choice comes down to how the whole system, not just the battery, fits your property and your installer's support.
