Generator silent since 16 March 2026
A farm and fabrication yard · No grid connection · One off-grid system from OGE
For farms, yards and rural businesses running on diesel generators.

The system
What's running the site
3× MultiPlus-II 48|15000 inverter/chargers · BYD battery stacks · SmartSolar MPPT RS 450. The retained AEM Gensets diesel generator stays on site — now backup, not primary.
The load
What it powers
A site like this requires far more power than a domestic house. A working fabrication shop — welders, machine tools and three-phase plant — all running off solar and battery.
Who you’re trusting with the job
Off Grid Engineering has designed, installed and monitored off-grid power systems since 2020. Victron Energy — the manufacturer behind the core kit — has featured our installs in three of its own films, including a 108-panel three-phase system for Scottish Woodlands, and lists us on its official installer network.
We monitor 141 systems on Victron VRM — more than a hundred reporting on any given day. If something needs attention, we usually see it before the customer does.
In the client's words
“Running a farm with multiple buildings is a big power demand — far larger than domestic needs — and I never imagined a solar system would manage it.”
“I heard about Off Grid Engineering through YouTube and liked the work they’d previously done for similar clients. Running a farm with multiple buildings is a big power demand — far larger than domestic needs — and I never imagined a solar system would manage it. From consulting through to install in December 2025, Scott and his team were extremely professional and kept tidy, high standards of work throughout. The system has saved us a significant amount compared with a conventional three-phase connection and its constantly increasing monthly bills. Our previous setup of generators was unsustainable, costing over £150 a week in fuel and maintenance. The 25-year guarantee on the panels and 10-year guarantee on the batteries also gives us confidence the system will serve us well into the future, and can be expanded as our power needs grow.”

The generator stays
Now backup, not primary
We didn’t take the diesel generator away. It’s still on site, wired in as backup. Day to day, the solar and battery run the yard and the generator sits silent — but it’s there if it’s ever needed. Going off-grid didn’t mean losing the fallback.
A system like this is a capital investment. Before you commit to anything, we’ll show you the payback maths for your own site — your diesel spend against real solar data.
