230 V single-phase power
Single-phase diesel generators for UK properties and businesses.
Explore 230 V Blackwell diesel generators for domestic, agricultural, telecom and smaller commercial loads, including UK-built Perkins options and practical automatic standby configurations.
Expert generator selection
Match the generator to a true single-phase load.
A single-phase generator is designed for sites supplied at 230 V where the protected circuits are single phase. Correct sizing must consider the total running load and the starting demand of pumps, compressors, refrigeration, workshop equipment and other motors—not simply the property’s main-fuse rating.
Automatic backup
A compatible automatic transfer switch can detect a mains failure, signal the generator to start and transfer the protected load once voltage and frequency are stable.
- Auto-start controller
- ATS integration
- Battery and heater options
Plan motor starting
Motors can demand several times their normal running current during starting. Provide pump, compressor and refrigeration details so the alternator and engine are not undersized.
- Largest motor checked
- Starting method considered
- Future load allowance reviewed

What is the difference between single-phase and three-phase generators?+
Single-phase sets provide 230 V power for single-phase loads. Three-phase sets typically provide 400 V across phases and are used for larger commercial and industrial systems. The generator should match the site distribution and connected equipment.
Can a single-phase generator power a house?+
Yes, when correctly sized and connected by a competent electrical installer through suitable changeover equipment. Essential-load separation, earthing and starting currents must all be considered.
Do I need an automatic transfer switch?+
An ATS is recommended when the generator must start and take over automatically during a mains failure. Manual changeover may suit attended or occasional applications.
Which engines are available in Blackwell single-phase sets?+
The catalogue includes Perkins-powered Premium models and selected Baudouin-powered Blackwell ranges. Availability and final component specification are confirmed with the quotation.
