Generator power guide

300 kVA diesel generators.

Compare UK-designed and UK-manufactured 300 kVA diesel generator options and nearby ratings from Cummins, Perkins, Scania. Check the exact prime and standby output, engine and enclosure before selecting.

Compare exact outputs

Options around 300 kVA.

A rounded GPS model class is not a guaranteed duty rating. The tables below identify the actual documented output for each reference configuration.

Larger site and facility loads

Specify 300 kVA around your load.

For larger commercial sites and industrial equipment, assess the largest load step, motor starting, nonlinear loads and the operating duty. The steady-state kVA total alone does not settle the generator size.

At a power factor of 0.8, 300 kVA corresponds to 240 kW mathematically. That conversion is not a substitute for the manufacturer’s duty rating or a starting-load assessment.

Discuss your load schedule
Does a 300 kVA model deliver 300 kVA continuously?

The model class alone does not establish continuous capability. Check prime and standby ratings and the manufacturer’s load-profile conditions. Confirm the intended run hours and average load when requesting a quotation.

Can I get a canopied 300 kVA generator?

Compare the canopied entries above, then confirm enclosure dimensions, sound requirements and final duty rating with GenPro.

Which engine brands are available at this output?

The comparison above includes Cummins, Perkins, Scania. Some are close alternatives rather than an exact match; use the electrical rating table to compare them.
