How Battery-Only Storage Can Save You Money
Many electricity tariffs offer cheaper electricity overnight or during selected off-peak period
A Sigenergy battery can be programmed to:
- Charge from the grid when electricity is cheaper
- Store that lower-cost electricity
- Power your home during more expensive periods
- Reduce your reliance on peak-rate electricity
In simple terms:
Buy electricity when it’s cheaper. Store it. Use it when it’s more expensive.
This process is sometimes called energy tariff arbitrage or time-of-use energy management.
Example of Potential Savings
Imagine your home uses approximately 10 kWh of electricity per day.
At a peak electricity rate of 30p per kWh, 10 kWh would cost approximately:
£3.00 per day
If the battery can instead be charged overnight at 10p per kWh, the same 10 kWh would cost approximately:
£1.00 before battery losses and other tariff considerations
This creates a potential difference of approximately:
£2.00 per day
Over a year, this could represent a significant saving.
Actual savings will depend on:
* Your electricity tariff
* The difference between peak and off-peak rates
* Household electricity consumption
* Battery capacity
* Battery efficiency and operating limits
* Charging and discharge schedules
* Standing charges
* How much electricity can be shifted from expensive to cheaper periods
Savings are not guaranteed and should be calculated using your actual electricity usage and tariff.
Why Choose Sigenergy?
The Sigenergy SigenStor is a smart, modular battery-storage system designed to manage energy intelligently. The system can help you:
- Reduce peak-time grid consumption
- Monitor your energy usage
- Prepare for future solar installation
- Store cheaper electricity for later use
- Manage charging and discharge schedules
- Improve control over your household energy costs
The mySigen app allows you to monitor your battery and household energy use from your phone.
Intelligent Energy Management
The Sigenergy Energy Management System acts as the intelligent control centre of the installation. It helps manage energy flows between:
- The electricity grid
- Your battery
- Your home
- Future solar generation, where applicable
The EMS can be configured around your electricity tariff and household demand, allowing the battery to charge during cheaper periods and discharge when electricity prices are higher.
This means the system can operate automatically in the background without requiring you to manually control it every day.
No Solar Panels Required
A battery-only system can be suitable even if you do not currently have solar panels.
You can install battery storage now and add solar generation later, subject to system design and technical suitability.
Battery storage may be particularly suitable if you:
* Use a reasonable amount of electricity each day
* Have access to a cheap overnight or off-peak tariff
* Use significant electricity during daytime or evening peak periods
* Have an electric vehicle
* Have a heat pump
* Have high household electricity demand
* Want greater control over when you buy electricity
* Want to reduce exposure to peak electricity prices
* May want to add solar panels in the future
Monitor Your Energy from Your Phone
The mySigen app allows you to monitor:
- Battery state of charge
- Grid electricity usage
- System performance
- Charging schedules
- Household electricity consumption
- Battery charging and discharging
- Energy flows around your home
- Operating modes
This gives you a clearer understanding of how your battery is being used and where your electricity is coming from.
Is a 9.04 kWh Battery Right for Your Home?
The right battery size depends on how much electricity you use and when you use it.
A 9.04 kWh Sigenergy battery can provide a useful amount of storage for shifting electricity from cheaper overnight periods into more expensive daytime and evening periods.
Larger households or properties with higher electricity consumption may benefit from additional battery capacity.
At Green Squirrel Energy, we assess your electricity usage and tariff before recommending a system. This helps ensure that the proposed battery is suitable for your home and expected energy requirements.

I honestly can’t recommend Green Squirrel Energy highly enough! From the very first survey, I felt like I was dealing with people who genuinely cared about doing the job properly rather than just making a sale. After discovering our roof had been poorly installed by another company, they took the time to explain everything clearly, showing us exactly what was wrong and why it needed replacing. There was never any pressure—just honest, professional advice that gave us complete confidence in their recommendations. The workmanship has been absolutely outstanding. Our new roof looks beautiful, and the integrated solar panels are so sleek that they blend in perfectly. The team also installed a Tesla Powerwall and handled all of the complicated electrical upgrades, including liaising with the DNO and sorting out the export limitation process. They made what could have been a very stressful experience completely hassle-free. Every member of the team was friendly, respectful and incredibly hardworking. They kept us informed throughout the project, left everything tidy each day, and their attention to detail was second to none. We now have total peace of mind knowing our home is protected by a properly installed, high-quality roof, and it’s wonderful seeing our electricity bills reduce while generating our own clean energy. If you’re looking for a company that values quality, honesty and customer service, Green Squirrel Energy is the one to choose. Thank you to everyone involved—you’ve completely transformed our home, and I wouldn’t hesitate to recommend you to family and friends!Posted on Google![]()

Recently had a Worcester Bosch air conditioning system installed and I'm really happy with it, installation was carried out professionally, with great attention to detail. Anthony, Alan and the guys were great from start to finish, they took pride in delivering a first-class installation. Had it for over a week now and It’s made a huge difference to my room and the upstairs area, delighted with both its performance and the quality of the installation. A special mention also goes to the Green Squirrel Energy Project Manager, who was communicative throughout, kept me informed every step and worked hard to find the right solution during a period when there was an equipment shortage. Especially in the summer where there is demand and waiting lists elsewhere, they gave me a date within 2 weeks and kept their promise, their commitment to customer service and problem-solving really stood out. Overall, an excellent experience! Highly recommend them to anyone considering air conditioning installationPosted on Google![]()

Outstanding Air Conditioning Installation in High Legh – A Five-Star Experience. We recently had air conditioning installed in our family home in High Legh by Green Squirrel Energy, and we genuinely couldn’t be happier with the entire experience. From the very first enquiry, the team were professional, friendly, and incredibly knowledgeable. They took the time to understand our home, our needs as a family, and how we wanted to use the system throughout the year. Nothing felt rushed or pushed – just honest advice and clear guidance. The installation itself was carried out to an exceptionally high standard. The engineers were punctual, respectful of our home, and worked with real care and attention to detail. Every aspect of the job was completed with precision, and the finish is absolutely flawless. You can tell straight away that they take real pride in their workmanship. What really stood out to us was their reliability. Everything happened exactly when they said it would – from initial survey to installation day. Communication was excellent throughout, and we always felt informed and confident in the process. The system itself has transformed our home. It’s quiet, efficient, and provides perfect comfort for the whole family, whether we’re cooling down in the summer or adding a bit of warmth in the colder months. Green Squirrel Energy delivered not just a service, but a genuinely outstanding experience. Their professionalism, reliability, and exceptional workmanship set them apart, and we wouldn’t hesitate to recommend them to anyone considering air conditioning installation. A truly five-star company.Posted on Google![]()

“We recently bought a new home that needed a complete renovation, and we wanted to create a highly energy-efficient property with integrated underfloor heating, solar panels, battery storage and an air source heat pump. Green Squirrel Energy designed and installed the entire system, and the experience has been fantastic from start to finish. The team were professional, knowledgeable and easy to work with, coordinating everything seamlessly during the renovation. The quality of workmanship has been excellent, and we’re delighted with the finished result. I wouldn’t hesitate to recommend Green Squirrel Energy to anyone looking for a complete renewable energy solution.”Posted on Google![]()

When my gas boiler broke down and was not worth repairing I knew it was time to investigate an air source heat pump. I have a dormer bungalow built in 1962. 5 months before I had installed a new insulated roof, solar panels and a 9kW battery so a heat pump is in line with my eco values. I had 3 quotes and each one suggested that a different level of work was required concerning changing the pipework and radiators. Alan from Green Squirrel’s approach made the most sense to me. He was recommended to me by Octopus. From the beginning he was highly attentive. He understands the importance of the quality of the install in order for the heat pump to work well. Alan invested many hours in the planing stage before I gave him the job. He appreciated the huge financial investment so was keen for me to understand how this system works and to ensure that my home was made suitable. The whole team were outstanding and the work was completed in the time quoted. As I needed new pipework there was some disruption but all was made as easy as possible. I felt that both Alan and Simon, the engineer, really wanted me to be happy with all the work and for everything to work well. So far the heat pump is working perfectly though I have not had my first winter yet. I have felt very happy with the after install service as Alan has kept in touch and encouraged me to contact him with any questions or issues. I have no difficulty in recommending their work.Posted on Google![]()

I recently had a full renewable energy system installed by Green Squirrel Energy at my house in Lymm. I first reached out to Alan at Green Squirrel about 9 months before I actually needed anyone on site. It was right at the start of a full house renovation and, even at that early stage, I could tell they were the right fit. Alan didn’t just give me a generic quote; he went away, had the proper calculations done, and worked through a solid plan for the property. We had a bit of back and forth on the final design—which I really appreciated—because it meant we landed on a setup that actually suited the house rather than a "one size fits all" solution. The project was massive: Solar, Powerwall 3, a full heating system, including a heat pump and underfloor heating throughout the downstairs. The installation was handled by Simon and his team, and they were great. If you’ve ever done a big renovation, you know how much of a headache it is coordinating different trades, but the Green Squirrel guys worked brilliantly with my builder to keep things on track. They weren't just in and out; the quality of the finish was clearly important to them. Now that the dust has settled and the longer days are finally here, the system is performing exactly as Alan promised. The house is perfectly comfortable year-round (the underfloor heating is a game-changer), and seeing the solar and battery kick in now the sun is out is a great feeling If you want renewable tech installed by a local firm that are knowledgeable, high quality and actually seem to care, I’d highly recommend Green Squirrel.Posted on Google![]()

Alan and his team did a fantastic job for us. The advice was sound, the work well planned and expertly delivered by considerate professionals. There was none of the common heavy sales patter, instead considered unpressurised advice. Alan went out of his way to advise on any (occasional and unavoidable) changes to plan. He also managed the project between the different parts of his team (e.g. roofers, electricians, etc.). I would have no hesitation in recommending him and the Green Squirrel team.Posted on Google![]()

Very good advice and support from Green Squirrel Energy. Background to this - heat pump installed in 2012 (fairly early adopter). The heat pump has always worked ok - in my view - but I have not been so confident in the control system. We have struggled to get house warm. With increasing frustration with the lack of F2F support from original installer I searched online to see if anyone locally and found Green Squirrel Energy from Knutsford (we live close). Contacted them more in hope than expectation - but they quickly phoned back and I engaged them to do a diagnostic on the system. Simon came to visit and they came up with a plan to improve - which wasn't going to be cheap...but I was up for that. Credit to them - they discussed amongst themselves and came to the view that although their proposal was perhaps ideal, it was difficult to guarantee the outcome given the original install. They then came up with a more cost effective solution with which I agreed to proceed. Credit to them that they didn't try to sell me the most expensive solution.... The solution was a new (Hive) control system which Simon and their electrician installed in a morning. I have also installed Hive TRV's on all the radiators. (I should also mention that as part of this work I have also undertaken a DIY change to 2 downstairs radiators and have installed a Strada Hybrid - so I also need to give a 'shout out' to David and his team at the Radiator Centre, Leamington Spa) Alan and Simon also took the time to educate me on how to get the best out of air source heat pump system by leaving it running 24/7 - I was treating it like a gas fired central heating system, but no-one had ever told me different. The result has been transformational - we now have a comfortably warm home for the first time in 13 years. Yes it's costing some money to run, but we were spending a fair amount before and weren't warm... I am very pleased with the service and support we have had from Alan and Simon and give them respect for coming up with a more cost effective solution when they could have sold me something more expensive.Posted on Google![]()

I used Green Squirrel as a one stop shop for the design and installation of my underfloor heating system combined with an Octopus air source heat pump. The whole process was very efficiently managed . The installers and technical leads, Simon Fagan and Andrew Hassell worked very efficiently on the install, showing me how everything worked and demonstrating the Octopus app (which is, like everything I have dealt with from Octopus, absolutely fab!). I am looking forward to a very cosy winter in my new house. Many thanks to you all.Verified by TrustindexTrustindex verified badge is the Universal Symbol of Trust.
