Power cuts across the North of England. Would your solar system keep the lights on?

For most homes, the answer is no.

Even if you have solar, standard grid-tied solar systems shut down during a power cut, even when the sun is shining.

That’s where battery storage with proper backup capability makes the difference.

With the right system, you can keep essential appliances running, protect against grid outages and make better use of your solar energy.

Solar reduces your reliance on the grid. Battery backup keeps you powered when it fails.

At Callidus, we design reliable Victron Energy battery storage and backup systems built around your needs.

Don’t just generate your own power. Take control of it.

Richard was able to get up and running with full power in just one day with one of our pre-built Victron and Pytes Off-Grid Systems.

If you're looking to go off-grid all you need is a competent electrician and you can up and running ASAP.

Maybe you are an electrical installer turning down off-grid opportunities because it’s not your area of expertise? ⚡🔋

You don’t have to!

This system was supplied to an electrical installer with no previous off-grid experience.

At Callidus Trade, we can design, quote and build complete off-grid systems, ready for you to install.

You bring the customer, we’ll bring the expertise.

Don’t miss out on opportunities simply because off-grid isn’t your speciality.

These are the scenarios that are being played out and are becoming more and more likely as day by day moves on. These are why we build the systems we do for people who want to prevent losing power and potential power cuts, now, this could just be because of storms or, believe it or not, due to hot weather, where a potential disaster hit in the summer with a lack of power, or where we have situations like this video. It's quite an eye-opener how vulnerable we really are.

Still powering your home or business with diesel?

Diesel costs keep rising, but the cost of the fuel is only part of what your generator is costing you.

If your property or business relies heavily on a diesel generator, a properly designed solar and battery system can dramatically reduce the hours that generator needs to run.
☀️ Generate power from solar during the day
🔋 Store surplus energy for use day or night
⛽ Significantly reduce diesel consumption
🔧 Reduce generator running hours and servicing
💷 Extend generator life and delay expensive replacement
🔇 Reduce noise and vibration
🌫️ Reduce fumes and local emissions
⚡ Provide instant, uninterrupted power from the battery system
📉 Reduce exposure to future fuel-price increases
The generator doesn’t necessarily disappear. Instead, it becomes backup, automatically starting only when the system actually needs it.

For many off-grid homes, farms and businesses, that can mean going from a generator running for hours every day to it running only when required.

At Callidus Trade, every system is individually designed around your actual power consumption, available solar and required autonomy, from smaller off-grid homes through to large commercial installations.

If you're spending thousands on diesel every month, talk to us. There may be a much better way to generate your power.

Need more power than the grid can supply?

A limited grid connection doesn’t have to limit what you or your customers can do.

Callidus Trade designs bespoke power and energy-storage systems around the individual site and its requirements, helping overcome grid constraints and enabling:

⚡ More available power
☀️ Larger solar installations
🚗 Faster EV charging
🔋 Battery-supported peak demand
🏭 Expansion without necessarily upgrading the incoming supply

You don’t need previous experience with these systems.

We design and configure the solution for the application and can provide full remote commissioning assistance, technical support and on-site guidance where required.

Whether you’re an electrical contractor looking to offer larger energy-storage projects or a commercial customer constrained by the available grid supply, we can provide the engineering and support behind the solution.

You install it. We’ll help you make it work.

⚡ What a show! Solar & Storage Live 2026 🔋

After a fantastic few days, we wanted to say a massive thank you to everyone who visited the Callidus Trade stand.

The stand was incredibly busy, and we had some brilliant conversations with installers, engineers, manufacturers, developers and customers about everything from off-grid homes and grid-limited sites to large-scale battery storage and multi-megawatt microgrids.

This year we were particularly excited to showcase our Victron distributed microgrid, Pytes low and high-voltage battery solutions, Maxxiom outdoor Victron enclosures, and some of the new technology we’re developing for much larger and more complex energy projects.

The level of interest genuinely exceeded our expectations, and we’ve come away with plenty of exciting projects and opportunities to follow up.

Most importantly, it was great to put faces to names, catch up with existing customers and partners, and meet so many new people from across the industry.

A huge thank you to our team, our partners and everyone who helped make the stand happen. There was a serious amount of work behind the scenes!

If you saw something on our stand that you’d like to know more about, drop us a message or get in touch with the Callidus Trade team.

Onwards to the next one! ⚡💙

Well, that didn’t take long to prove its worth.

Yesterday I shared this Callidus pre-built Victron system, installed by one of our trade partners to provide resilience for a customer’s critical IT infrastructure.

Just one day after installation, the entire industrial estate suffered a power cut.

For this customer, however, the system did exactly what it was designed to do.

Their critical IT infrastructure remained operational, protecting the systems relied upon by around 80 people and allowing the business to continue operating while the surrounding estate was without power.

The system combines 6 × 15 kVA Victron MultiPlus-II units — two per phase — with 117 kWh of Pytes V12 battery storage, an external transfer-switch architecture and integration with the customer’s existing rooftop solar.

Battery storage is often discussed in terms of energy savings and solar utilisation. But for a commercial customer, the value of resilience and business continuity can be considerably greater.

In this case, it took one day to demonstrate exactly why the investment was made.
