Battery Storage in Central Scotland

Store more of your own electricity, make better use of lower-cost tariffs and take greater control of your home energy with an intelligently designed battery storage system.

Renewable Heat installs tailored home battery systems across Central Scotland, including modular Sigenergy solutions that can expand as your household energy needs grow.

Why Choose Home Battery Storage?

Electricity is not always generated or priced at the moment you need it. Solar panels typically produce the most power during the day, while many households use more electricity in the morning and evening. Battery storage helps bridge that gap.

A home battery stores surplus solar electricity so you can use it later rather than exporting it straight to the grid. It can also charge during lower-cost tariff periods, allowing you to draw on stored electricity when grid prices are higher.

Whether you already have solar panels or are planning a wider home energy upgrade, battery storage can help reduce your reliance on the grid, improve your solar self-consumption and give you more control over your ongoing electricity costs.

Modern systems can also be designed to support future additions such as a heat pump, EV charger or backup power, creating a smarter and more resilient home energy system.

How Home Battery Storage Works

A home battery stores electricity until your property needs it. When paired with solar panels, the electricity generated on your roof powers your home first, while any surplus is used to charge the battery rather than being exported immediately to the grid. As solar generation falls or household demand increases, the battery releases that stored energy to power your appliances, helping you use more of the electricity your panels generate.

A battery can also charge from the grid during cheaper off-peak periods, then supply your home when electricity prices are higher. Smart controls manage when the system charges and discharges based on your generation, household demand, tariff and battery level. Depending on the system and how your household uses energy, battery storage can increase solar self-consumption from around 30–40% to as much as 70–80%.

Battery Storage FAQs

Yes. A standalone battery can charge from the grid during lower-cost tariff periods, then provide electricity later when prices are higher.

This can help households make better use of time-of-use tariffs even if they do not currently have solar panels. The system can also be designed so solar PV can be added later.

In many cases, yes. Battery storage can often be added to an existing solar installation using either an AC-coupled or DC-coupled arrangement.

The best approach will depend on your existing inverter, the age and configuration of your solar panels, available space and what you want the battery to achieve. We will assess your current system before recommending the most appropriate option.

The right battery capacity depends on how much electricity you use, when you use it, the size of any solar PV system and whether you have technologies such as a heat pump or electric vehicle.

A battery should be large enough to store a useful amount of electricity without being routinely underused. We analyse your energy consumption and future plans before recommending a system size.

Yes. Many homeowners choose to install battery storage alongside their solar panels, while others add a battery later. We’ll design a system that can meet your current needs while allowing for future upgrades where possible.

A stackable battery is made from individual modules that fit together to create the required storage capacity.

You can start with the capacity your home needs today and add compatible modules later if your electricity consumption increases. This can be useful if you plan to install a heat pump, buy an electric vehicle or expand your solar panel system in future.

SigenStor is an integrated home energy system from Sigenergy. It can combine battery storage, a solar inverter, battery power conversion, energy management and optional EV charging within one modular platform.

Its stackable design allows storage capacity to be configured around the property and expanded as energy needs change.

Yes. SigenStor uses modular, stackable battery units, allowing compatible modules to be added as household electricity needs increase.

Each battery pack includes its own optimiser, which Sigenergy says allows batteries of different ages and capacities to operate together within a compatible system. The exact expansion options will depend on the original installation and current product compatibility.

Battery storage can reduce the amount of electricity you need to buy from the grid at more expensive times.

The biggest savings usually come from storing surplus solar electricity for later use or charging from the grid during cheaper tariff periods. Actual savings will depend on your energy use, tariff, system size and how the battery is configured.

Yes. Many modern battery systems can be programmed to charge during lower-cost off-peak periods.

The stored electricity can then be used when tariff rates rise. This can be particularly useful during winter, when solar generation is lower but household electricity demand is often higher.

A battery does not automatically provide backup power simply because it is installed.

Backup operation requires a compatible battery, suitable gateway and dedicated electrical design. Depending on the chosen system, selected essential circuits or a larger proportion of the home may be supported during a power cut.

We will discuss the level of backup you need before designing the system.

A system may be designed to support essential circuits such as lighting, broadband equipment, refrigeration and selected sockets.

The equipment that can run, and for how long, depends on the battery’s capacity, power output, stored charge and household demand at the time.

High-demand appliances can drain a battery quickly, so backup systems should be designed around clear priorities rather than optimistic guesswork.

The best location depends on the battery model, manufacturer requirements, property layout and electrical connections.

Suitable systems may be installed in a garage, utility area or approved outdoor location. The space must provide safe access and meet current electrical, fire safety and manufacturer requirements.

SigenStor is IP66-rated, which provides flexibility for suitable indoor or outdoor installation, although every proposed location must still be assessed properly.

Smarter Energy Starts with Storage

Battery storage gives you greater control over the electricity entering, leaving and moving around your home.

Whether you want to retain more of your solar generation, make better use of an off-peak tariff or prepare for future technologies, we can design a system around the way your household actually uses energy.

0% VAT

Eligible residential battery storage and associated installation equipment currently benefit from 0% VAT, helping reduce the upfront cost of adding storage to your home.

Interest-Free Funding

Our Testimonials

This was a challenging installation, given the size and weight of the heat pump unit with integrated tank and the need to connect it to existing pipework routing. The job took a day longer than expected as a result, but one of the company directors came out on the extra day to make sure the teething problems were sorted and to ensure that we had heat and water again (sacrificing his attendance at a social event as a result). The company obviously have a good support relationship with the manufacturer (Stiebel Eltron), who had a local technician available on the phone to work through issues in the commissioning, and there has been good technical support from Renewable Heat in the weeks since the installation, advising on heat curves and optimisation. During the planning/quoting stage, Renewable Heat were also very good at advising on what might be beneficial and what might be unnecessary, as a result of which we saved a lot of money on an additional hot water tank.

Grant Macaskill
Very amiable and professional guys and quality materials. However, the new boiler won’t kick in to support heat pump regardless of sudden boost demand to background temp as per the hybrid design. Glitches with the controls I’ve not been shown or not permitted to restore communication between boiler and heatpump using the RF controller or app for an £11k+ system, I’d rather be more in charge of my own house and equipment. I felt a bit harangued for final 40% invoice which was due immediately. I used the HES Loan system which installer knew as I showed them the agreement which had an end date of October and they agreed to proceed. I applied for drawdown as soon as I got equipment delivery invoice and paid them the same day in July. but because of difficulties with the supply chain for the External Wall Insulation from BCA in Shotts I couldn’t get my post EPC for both measures until end September but still within timeframe.

We are delighted with Renewable Heat’s installation of an ASHP in our 1940s bungalow. Chris did an excellent job (the pipe work is a work of art!) and was incredibly knowledgeable about all aspects of the system, so we are really grateful to him for his precise attention to detail. This was a retrofit replacing our old gas boiler and there were some hurdles to overcome (radiators in awkward places needing re-piped), but everything from the initial quote to the final sign-off was expertly handled and we would highly recommended the company to anyone looking for an ASHP.

The Renewable Heat team have been excellent from the very start of the process (getting a suitability assessment of our property done) – to having the work completed over the course of a couple of weeks in the summer. The engineer team were professional at all times and any of the numerous problems that our strange house threw at them they overcame without any fuss or bother. I highly recommend Renewable Heat to anyone looking to have an air source heat pump fitted.

The team at Renewable Heat were exceptional and their knowledge of the Ground Source Heat Pump was impressive. Any questions or queries I had they answered promptly and detailed. They were also extremely tidy which is an added bonus! I can not recommend this company enough.
C.Hutton
Overall, extremely happy with the service and although I only gave a 4 star for ‘value for money’ this is not a reflection on the installing company – it is just a reflection of the cost in general for this sort of technology. Costs need to come down to a more affordable level in order for the masses to jump onboard with the notion of installing renewable energy.

Most impressed by the way in which Barry conducted his initial survey of our property and the advice he gave. We had other suppliers surveying too, but the thoroughness with which Barry and his people carried out their work impressed both myself and my wife. We believe we definitely made the right choice of installer.
John MacKenzie

Great, friendly, and professional team – almost didn’t want to cover the beautiful copper work up behind a cupboard. The system is running perfectly, just need winter to arrive to fully test it. Recommended.
