⚡ Has your off-grid system run out of power?

At Historic Helicopters, their original three-phase off-grid system was no longer large enough for the growing site.

Instead of replacing everything, we expanded it — doubling the available power from 10 kVA to 20 kVA per phase, increasing battery storage to 108 kWh and adding 40 kW of solar PV.

The original equipment stayed in service as part of the new system.

A good off-grid system shouldn’t just work today — it should be designed to grow with you.

From individual properties to multi-megawatt systems, the same principle applies: build the power system around what the site actually needs.

Our distributed Victron microgrid approach allows solar, battery storage and inverter capacity to be added in stages and connected through a 3-phase AC microgrid. A system can start small and grow as demand increases — from a single home or commercial building through to a housing development or major industrial site.

It can also solve the problem of a limited grid connection. If the grid can only supply, for example, 100 kW but the site occasionally needs 200 kW, the battery and inverter system can provide the additional power while keeping the grid import within its limit. This can allow much larger equipment, machinery, EV charging or other high-demand loads to operate without necessarily having to increase the grid connection.

It also provides greater resilience. Because generation, storage and inverter capacity can be distributed around the site, a fault in one part of the system does not necessarily take everything down. Other sections can continue operating, reducing the impact of a failure and helping maintain power to critical loads.

The result is a power solution that can be:

Grid connected
Off-grid capable
Used to overcome grid capacity limitations
Expanded as demand grows
Designed for greater resilience

A practical way of building reliable energy infrastructure phase by phase, rather than installing everything on day one.

Today I had the pleasure of spending the day at UTC Newton Abbot taking part in mock interviews with Year 11 students.

It was genuinely encouraging to see the enthusiasm, ambition and practical skills coming through from the next generation.

A few examples that really stood out
�🔹 One student had built their own electric bike at home
�🔹 Another set themselves the goal of saving £1,100 by working for neighbours and others in the garden for a year for a PC to help with their college work and future development. Which he then built himself from parts.
�🔹 Many others spoke confidently about the projects, challenges and goals they are working towards.

It was refreshing to meet young people who are not just thinking about qualifications, but are actively building practical skills, solving problems and investing in their own future.
