It starts with a free 7-day power audit
We fit a power logger to your generator supply and leave it for seven days. It records what the site actually draws, hour by hour. You get a short report showing where the fuel is going, which loads could run on solar and batteries, and how many generator hours that would remove. If the numbers don’t stack up, we’ll tell you.
- Rising fuel costs, and no idea which loads are burning it Diesel is the bill you can see. What you can't see is which loads are driving it, or how much of the run-time is the generator idling for a fraction of its capacity.
- Running through the night and over the weekend Most sites run a generator sized for the busiest hour, all the hours. The noise is constant, and the fuel goes on burning long after everyone's gone home.
- Servicing, refuelling, call-outs — and someone's time Every service interval, every fuel delivery, every breakdown is somebody's afternoon. That cost never shows up on the diesel invoice.
- Every hour it's down is an hour the site isn't working Generators fail. When yours does, the offices, the servers, the security and the weighbridge go with it — and that's usually the expensive part, not the fuel.
- Nobody has ever measured what the site actually uses Almost every site we survey is running on an assumption made years ago. Seven days of real data usually surprises people — sometimes in their favour.
And when the generator stops, the site doesn't
Solar and batteries don’t just cut fuel. They keep the critical loads running — offices, servers, security, lighting, the weighbridge — through refuelling, through servicing, and through a breakdown.
Most sites we survey have their generator down more often than they’d care to admit. That’s usually the part that costs real money, not the diesel.
