Perkins 404A-22G1 22 kVA Generator: Power for Mid-Scale Backup

Why 22 kVA Is a Workhorse Output Level

At 22 kVA standby (17.6 kW) and 20 kVA prime, the Perkins 404A-22G1 sits in the range that contractors, rental companies and facility operators return to again and again. It is large enough to carry a meaningful load of tools, lighting, small plant and critical control circuits, yet compact enough to be moved, installed and serviced without heavy lifting equipment.

Engine and Alternator Configuration

The set is built around the Perkins 404A-22G1 diesel engine paired with a NEKRA ARK 184E alternator, delivering 400 V, 50 Hz, three-phase power. This pairing is designed for steady, continuous duty rather than peak performance, which is exactly what standby and prime applications demand.

Fuel and Runtime Considerations

The 62 L fuel tank combined with a consumption rate of 4 L/h at 75% load gives operators a realistic picture of on-site endurance. For rental fleets and temporary site power, this balance between tank capacity and machine weight (528 kg) means the set can be positioned where it is actually needed without a dedicated fuel bowser sitting alongside it.

Silient Enclosure and Site Use

At 68 dB(A) measured at 7 metres, the canopy configuration makes the unit considerably easier to deploy near occupied buildings, workshops or event areas where a loud open set would restrict placement. The overall footprint of 1530 x 900 x 1120 mm keeps it within a standard shipping and handling envelope.

Control, Monitoring and Remote Visibility

The Trans-AMF controller with optional DSE provides automatic start/stop logic, while RS-485 and GPRS communication allow remote monitoring and event and alarm history tracking. Standard equipment includes an automatic transfer switch control, battery charger, emergency stop button, heavy-duty air filter and fuel tank level gauge — a practical list for any site supervisor checking readiness before a shift.

Typical Applications

• Construction sites powering tools, temporary lighting and small plant
• Rental fleets supplying temporary power to events and workshops
• Small commercial premises and shops as standby cover
• Agricultural operations running pumps and essential machinery
• Telecom, small data and control rooms requiring clean, automatic backup
