Rebelvolt e-Generators power cranes, tools, cabins and EV chargers on sites where the grid is weak, expensive or missing. Silent operation, no fumes, and up to 70% less diesel when used with existing diesel generators.
Construction challenges we solve
Power where the grid can't keep up
New electric machinery, chargers and high peak loads
Grid upgrades are slow and expensive
Fuel, noise and emission pressure
Regulations push towards low-emission sites
Diesel generators are loud, smelly and bad PR for “green” projects
Project and rental economics
Fuel bills and generator maintenance eat margin
Underutilised diesel generators sized for worst-case peak
Why construction & rental companies choose Rebelvolt
Diesel savings & ROI
Up to 70% diesel savings in paired use with existing generators
Leasing models turn a 6-figure investment into a monthly fee that is lower than your fuel savings
Site-friendly power
Low local emissions, no soot, no diesel smell
Whisper-quiet operation enables better working conditions and fulfils noise restrictions
Arctic engineering
Operating temperature from -35°C to +60°C with smart temperature control
Designed and manufactured in Finland, built for snow, mud and real winter
Plug-and-play with existing diesel fleet
Auto start/stop charging from diesel generators based on state of charge
Use smaller or fewer diesel generators, extend maintenance intervals, keep redundancy
Typical setups
High-usage urban site
Two tower cranes + electric equipment
Setup: One Trailer e-Generator (200 kW / 400 kWh) + existing diesel generator as backup
Result: Diesel used mainly for charging and peaks, cutting fuel cost and noise
Rental fleet
Rental company adds pallet and trailer e-Generators to generator fleet
Setup: Pallet systems for small sites/events, trailer units for large sites
Result: New “green power” category with better margins and stickier customer relationships
Evidence from the field
Off-grid construction site reference case
One month actual test case, Northern Europe
A rental company and a construction customer tested a trailer-based e-Generator in parallel with an existing diesel generator. The e-Generator carried the continuous load; the diesel unit only charged the battery when needed. This way generator achieved near optimal efficiency.
