Generator power guide

40 kVA diesel generators.

Compare UK-designed and UK-manufactured 40 kVA diesel generator options and nearby ratings from Baudouin. Check the exact prime and standby output, engine and enclosure before selecting.

Compare exact outputs

Options around 40 kVA.

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

Compact backup loads

Specify 40 kVA around your load.

At this scale, confirm whether the supply must be single or three phase. Pumps, compressors and refrigeration can have starting requirements well above their running load.

At a power factor of 0.8, 40 kVA corresponds to 32 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 40 kVA model deliver 40 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 40 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 Baudouin. Some are close alternatives rather than an exact match; use the electrical rating table to compare them.
