What is the Sigenergy SigenStor battery system?
SigenStor is an integrated energy storage platform for homes and businesses. Sigenergy describes it as a 5-in-1 system combining a solar inverter, battery power conversion system, battery modules, energy management system and optional AC/DC EV charging. Bringing these functions into a modular design can reduce the number of separate components required and creates a clean, coordinated installation.
Unlike a fixed-capacity battery, SigenStor can be configured around your current requirements and expanded as your needs change. That makes it relevant whether you are adding battery storage to a new solar PV installation, upgrading an existing renewable energy system or planning for an electric vehicle.
Why choose a Sigenergy battery?
• Use more of your solar power: Store surplus electricity generated during the day and use it later, including in the evening when household demand is often higher.
• Reduce grid dependence: A correctly designed solar battery system can reduce the amount of electricity you need to import. Actual savings depend on your usage, tariff, system size and solar generation.
• Modular and expandable: Stackable battery modules allow the system to be tailored to the property, with scope to expand where the installation and product specification permit.
• Intelligent energy management: The mySigen app provides system monitoring and smart controls, helping you understand how energy is being generated, stored and used.
• EV-ready design: An optional Sigen EV DC charging module can integrate electric vehicle charging with the wider home energy system. Charging and vehicle-to-everything functions depend on the selected equipment, vehicle compatibility and regional requirements.
• Built with safety in mind: Sigenergy specifies multi-layer battery protection, including temperature monitoring, insulation and other protective measures.
• Suitable for indoor or outdoor installation: Current SigenStor battery specifications include an IP66 ingress-protection rating, subject to correct siting and installation.
How does Sigenergy battery storage work with solar panels?
When your solar panels generate more electricity than your property is using, the excess can charge the battery instead of being exported immediately. When solar generation falls or demand rises, the stored electricity can help power your home. Depending on your system design and electricity tariff, the battery may also be scheduled to charge from the grid at lower-cost times for use when rates are higher.
This does not mean every household will achieve the same savings. Roof orientation, shading, annual consumption, import and export tariffs, battery capacity and everyday routines all affect performance. Perrin Energy assesses these factors before recommending a system.
A future-ready battery for changing energy needs
Household electricity use rarely stays the same forever. You may add an electric vehicle, heat pump, home office or more solar panels. SigenStor’s modular approach gives an installer flexibility to specify a system for today while considering tomorrow. Its integrated architecture also keeps the inverter, storage, controls and optional EV charging within one product ecosystem.
Sigenergy warranty and long-term reassurance
Sigenergy’s European limited warranty currently lists a 10-year warranty period for the Sigen battery and Sigen Energy Controller, subject to its terms, product registration, operating conditions and exclusions. Warranty documents and eligibility requirements can change, so Perrin Energy will confirm the current cover for every product included in your quotation and provide the applicable manufacturer documentation.

It demonstrates how the modular battery units and associated equipment can be brought together in a tidy installation, with the final layout determined by the property, electrical design, manufacturer requirements and safe access for commissioning and maintenance.
What happens during a Perrin Energy assessment?
We begin by understanding what you want the system to achieve. We then review relevant information such as electricity consumption, existing or proposed solar generation, tariff arrangements, electrical supply, available installation space and possible future additions such as an EV or heat pump. This evidence-led approach helps us recommend an appropriate configuration rather than relying on a generic package.
Our installer’s view: A battery should be sized around the property and the customer’s objectives—not simply chosen by headline capacity. Good system design considers when electricity is used, how much solar energy is likely to be available and how the household’s needs may change.
Frequently asked questions about Sigenergy batteries
Can SigenStor be added to an existing solar PV system?
It may be possible to integrate battery storage with an existing solar installation, but the best arrangement depends on your current inverter, electrical supply, available space and system goals. A site assessment is the best way to confirm compatibility.
Can a Sigenergy battery provide backup power?
Backup capability can be included in suitable system designs, but it is not automatic for every installation. The required equipment, circuits to be supported and expected backup duration should be discussed during design.
What size Sigenergy battery do I need?
The right capacity depends on how much electricity you use, when you use it, the output of your solar panels and what you want the battery to achieve. Perrin Energy can use your consumption and generation data to recommend an appropriate configuration rather than simply specifying the largest option.
Is SigenStor suitable for homes and businesses?
Yes. SigenStor is designed as an energy storage platform for residential and commercial applications. The appropriate equipment and capacity depend on the site’s electrical demand, supply and installation requirements, so each project should be assessed individually.
Does a Sigenergy battery work without solar panels?
A battery may be configured to charge from the grid without solar panels, for example during lower-cost tariff periods. Whether this is suitable depends on your tariff, consumption pattern, system design and objectives. Adding solar PV can provide a source of on-site renewable electricity to store.
The mySigen app allows customers to monitor solar generation, battery charging and discharging, household consumption and grid interaction from one place. Available controls and displayed information depend on the installed equipment, system configuration and current software features.
SigenStor may be a good fit if you want to store surplus solar electricity, make greater use of time-of-use tariffs, add battery capacity as your needs change or bring solar, storage and optional EV charging into one coordinated system. Suitability still depends on your consumption pattern, electrical supply, available space, budget and future plans, which Perrin Energy reviews during the assessment.

A practical Lincolnshire guide to EV charging costs, off-peak tariffs, Solar PV, battery storage, and home EV charger installation

Switching to an electric vehicle (EV) can be one of the most effective ways to reduce day-to-day driving costs. Pair it with Solar PV, and the savings may be even greater. For homeowners in Lincolnshire, combining home charging with solar panels and battery storage can help reduce both motoring and household energy costs. Here’s a practical guide to typical electric car running costs in the UK in 2026, and how Solar PV can help lower EV charging costs further.

1. Electric car running costs in the UK in 2026
Using typical UK electricity prices in 2026, home charging is still usually far cheaper than running a petrol or diesel vehicle. For example, the average standard electricity unit rate for Direct Debit customers was 24.67p per kWh from April to June 2026, while some EV tariffs offered cheaper overnight rates from around 5.5p per kWh, depending on supplier, tariff, eligibility, and region.
• Standard daytime electricity: about 24–25p per kWh
• Some EV off-peak tariffs can start from around 5.5p per kWh, although rates vary by supplier, tariff, and region
• A 30kWh EV, such as a Nissan Leaf, can deliver roughly 140–160 real-world miles from a full charge
For most drivers, that works out at approximately:
• Around 6–8p per mile on a standard home tariff
• Around 2–3p per mile on a good off-peak EV tariff
• This is typically far less than petrol or diesel, although exact per-mile costs depend on fuel prices, vehicle efficiency, and driving style
2. How Solar PV can reduce EV charging costs
When you charge your EV with electricity generated by your own solar system, the savings can improve again. Instead of relying entirely on grid electricity, you can use more of your own power during the day or store it for later with a battery.
• You use electricity generated on your own roof
• You reduce your reliance on higher daytime rates
• You protect yourself from future energy price rises
With a typical 4–6kW solar system and a home battery, many households can charge their EV for just pennies, and on bright days some charging can effectively cost next to nothing.
Long-term value
Solar panels typically continue generating electricity for 25 years or more, so they can help support lower long-term motoring and household energy costs while reducing your exposure to future supplier price changes.

Frequently asked questions about EV charging, Solar PV, and battery storage in Lincolnshire
How much does it cost to charge an electric car at home in the UK?
The cost of charging an electric car at home depends on your electricity tariff, your vehicle’s efficiency, and when you charge. In 2026, many drivers can expect home charging to cost significantly less per mile than petrol or diesel, especially when using an off-peak EV tariff.
Can Solar PV reduce electric car charging costs?
Yes. If your solar panels generate electricity while your car is charging, or if you store solar energy in a home battery for later use, Solar PV can help reduce how much electricity you need to buy from the grid.
Is battery storage worth it for EV charging?
Battery storage can be worthwhile if you want to use more of your own solar electricity, reduce reliance on higher daytime tariffs, and improve flexibility over when you charge your EV at home.
Do I need a home EV charger if I have solar panels?
Not always, but a dedicated home EV charger can make charging faster, more convenient, and easier to manage alongside solar generation and off-peak tariffs.
Do Perrin Energy install Solar PV, battery storage, and EV chargers in Lincolnshire?
Yes. Perrin Energy helps homeowners across Lincolnshire with Solar PV systems, battery storage, and EV home charger installation designed to work together as part of a smarter energy setup.

If you’re comparing quotes for solar panel installation in Boston, Lincolnshire, Perrin Energy provides clear, personalised pricing—no pressure, just honest guidance on what will work best for your property.

As an independent, family-run installer, we prioritise honest recommendations over sales pressure.

Should you add battery storage?

Battery storage can increase the amount of solar electricity you use in your home by saving surplus daytime generation for evenings and early mornings. This can be particularly helpful for households that are out during the day, or anyone wanting more predictable savings as import prices change.

• Good fit if: you use most electricity in the evening, you want backup-like resilience (where supported), or you’re planning an EV charger.
• Less essential if: you’re at home during the day and can use power as it’s generated.
• Design tip: battery sizing should match your usage patterns—not just the biggest capacity available.

Smart Export Guarantee (SEG): getting paid for surplus solar

The Smart Export Guarantee (SEG) pays you for electricity you export to the grid when your solar panels produce more than youre using. In practice, you apply to an electricity supplier for an export rate, and payments are usually made as bill credit or paid out periodically. Eligibility commonly requires an MCS-certified installation and a compatible smart meter that can measure export, and you can usually choose an export tariff separately from your import supplier.

• Compare export tariffs: SEG rates vary by supplier and can change, so it’s worth shopping around.
• Maximise self-consumption first: using your solar power directly typically saves more per kWh than exporting.
• Keep your paperwork: you’ll need your installation certificates and meter details when applying.

Residential solar installation: why it’s worth it

Installing solar panels on your home offers long-term benefits:

• Lower monthly electricity bills
