Just wrapped up a new off-grid installation near Elgin, Scotland — 19 cabins powered by a hybrid system that really shows what’s possible when you rethink the design.
Diesel consumption was a key driver on this project. Traditionally, we’ve used a single 115kVA genset running at ~80% load, paired with a 90kVA inverter and 160kWh battery storage — burning around 18 litres per hour.
For this site, we took a different approach:
→ 2 × 45kVA generators
→ Each paired with a 45kVA inverter and 80kWh battery pack
→ Combined output delivering the same 90kVA inverter capacity and 160kWh storage
→ Plus 5kW of solar generation
The result:
Fuel consumption dropped to ~7.5 litres/hour per generator — 15 litres/hour combined. That’s a saving of ~3 litres/hour, without compromising performance.
Beyond the fuel savings:
• No AdBlue required — a big win for a remote site
• Built-in redundancy — if one generator fails, the other keeps the site live
• Greater flexibility in load management and improved overall resilience
This system was fully designed and built in-house, specifically for our own hire fleet — tailored to perform in real-world conditions where reliability matters most.
Always rewarding to analyse the data and see these efficiencies delivered on site.
