Battery storage can help optimise your energy usage, so whatever you require, solar batteries can help you get there.

Our lithium solar batteries can do an incredible 6000 cycles! In other words, when the batteries are being used correctly, this can give them a life span of 16.4 years.

Solar batteries are completely flexible, which means that they are useful for homeowners looking for a solution to keep the power they generate but don’t have high usage. You can reserve the power for a time when you truly need it, for example, in the evenings or when the weather is dark and gloomy.

What is a Solar Battery?

Solar batteries are ideal for using renewable energy to increase your independence from the grid. Our team at Callidus will provide you with information and advice to help you choose the right solar battery for you.

When solar panels generate energy, properties will immediately use the electricity or go to the National Grid, which pays for the power. However, at Callidus, our off grid solar systems have no connection to the Nation Grid, meaning that this is the ultimate way to keep self-efficient power.

Why Choose Callidus?

Due to having no connection with the National Grid, our power systems include a bank of solar batteries to store power throughout the day – then feeding this back to your Exeter property at night to create complete independence. Once your desired appliances are powered, any excess energy is sent back to the battery bank, drawing power from the batteries when the system is not generating power, for example, at night or when the clouds are cast over.

Our team of professionals will visit your property to go through a survey before the installation process begins; this will allow us to access the best route to follow regarding installing your new solar system and whether a solar battery storage unit is required.

At Callidus, we are a leading purveyor and installer of off grid solar systems within the UK with CHAS, RECC, NICEIC, TrustMark and MCS certifications. Due to our incredible 11 years of experience, you can be confident that you are getting the renewable energy service you deserve to care for your Exeter property.

Battery Storage

Smart Design



All solar batteries should be monitored regularly to ensure that they are charging correctly. In terms of manual maintenance, this typically refers to flooded lead acid, which can be done safely by a professional. Most of our batteries are plug-and-play systems, so this shouldn’t be an issue. However, as a safety precaution, our solar batteries are incredibly heavy, and we would advise against moving or lifting them once they have been installed. An average battery can weigh around 100kg.

These batteries are not like the ones within your TV remotes within your Exeter home. These can have cables and switches attached for monitoring and performance. Pylon lithium batteries are stored in a purpose built cabinet and come in banks of 4 – for further questions regarding our solar batteries, feel free to contact our team directly. Lithium batteries are much better at charging and discharging and prefer to be kept this way, although they have a limited working temperature. In other words, they are sensitive to hearing and work best between 15-25 degrees.

Battery Storage

Callidus strives to provide all our Exeter customers with the best solar batteries possible with various home storage battery solutions on the market. Due to constantly rising energy costs, many Exeter homeowners consider battery storage as an alternative to exporting electricity.

As certified installers of Tesla, we offer the Tesla Powerwall 2, which can effortlessly store electricity for later use. This design, paired with incredible market performance, can enable all Exeter homeowners to enjoy a reliable, clean and sustainable solution. As a fully integrated AC battery system, its rechargeable lithium-ion battery pack is ideal for a renewable energy source to complement your social panels.

In regards to a manufacturer, we can recommend Victron. With an incredible 45+ years of experience, high quality products are a must. Their battery storage options are incredibly user friendly and feature a remote control function via Victron VRM – you can monitor your solar system from anywhere!

Smart Design

The overall number of solar batteries that your system will need depends on the energy requirements of your property. However, due to our state of the art software, we can design your system to ensure that it delivers the perfect amount of power for your needs and requirements. Based on your power usage, we can give you recommended advice and guidance on your energy and how you can reduce your carbon footprint.

One of the main benefits of our systems is that they are designed to be expandable; this means that you can have the ability to add extra batteries, solar PV panels or an inverter to boost your power supply if you require it. To ensure that your solar batteries are working correctly, we test each component in a controlled environment to get the highest quality output possible.


If you have any following questions regarding our solar batteries, look at our Help Desk page for reference to our solar products. Otherwise, you can get in touch with us, and we will assist however we can. We want to make the switch to solar energy as seamless as possible for your Exeter property.

We look forward to hearing from you soon!


Happy Customers

The guys at Callidus were all fantastic. We had lots of questions before we had our solar power system installed, and all our many emails were answered very efficiently. The on site team did a really tidy job, and went through how we would use the system. We were very apprehensive about having an off grid system, and had different companies come to quote for the job. We went with Callidus because of the whole package that they offered, which includes their after sales help. We are very happy with the set up and it fulfils all that we asked for, very happy bunnies.

Maxine Heard

We live off grid in Cumbria and wanted to upgrade our electricity supply. We contacted Callidus and they were very happy to work with us. With excellent two way communication they designed the perfect system for us which is easily expandable if we should need it in the future. They were happy to design the system and supply us the parts for us to install ourselves. They programmed the system and were on the end of the phone to help with installation and getting the system up and running. Their after sales service is excellent. It has improved our quality of life no end.

Jack Beach

Fantastic customer service! Such incredibly helpful staff. Can’t rate them highly enough. Highly recommend this company. So helpful and really fast service. I spoke with Chris and Dave at a time when other staff where out and they went above and beyond to help.

Isobel Nancarrow

The entire team at Callidus, from the top to the bottom, are amazing. Knowledge, support, passion to place the customer and their needs at the centre of the process, throughout all phases. Clear explanations with realistic expectations; no over inflated figures to close out a deal. I am so satisfied with their approach that I have already completed an expansion of my system; NOT because it didn’t perform as promised, but in fact we are generating more than expected so have increased the battery storage!!

Marcus Rowe

I have just had an off grid solar system fitted by Steve and his team. It has been a completely stress free experience. Everyone was so professional, helpful and obliging, kind and friendly. I would recommend Callidus to anyone.
