22 kVA Diesel Generator Set: Where It Fits in Your Project

When a site needs backup power, the first question is rarely "which model?" but "how much is actually required?" A 22 kVA three-phase diesel generator sits in a useful middle ground: powerful enough to carry mixed loads, compact enough to move and install without heavy lifting equipment, and economical to run.

The Configuration

The Gobiz GBP-22 (reference GBZ-50551) is built around the Perkins 404D-22G, a four-cylinder diesel engine, paired with a Nekra alternator. Output is 400 V, 50 Hz, three-phase, with 22 kVA standby power and 20 kVA prime power — the standby figure being the headline rating for applications where the set must carry the full load on demand.

The enclosure is a silent steel canopy with a weld-free structure, anti-vibration pads, hidden exhaust and lockable doors. At 90 dB(A) measured at 7 metres, it is suited to sites where noise limits apply. Cooling is handled by a coolant heater, and the control panel is available through Datakom, Gobiz, Deepsea or Mebay, with AVR regulation, an ATS and an emergency stop button included.

Fuel and Runtime

The 65 L fuel tank is a meaningful part of the package. Fuel consumption is rated at 4.80 L/h at 50% load, so a tankful carries a full working day on a moderate duty cycle — useful for night-time coverage, event power or standby duty where refuelling is inconvenient.

At 518 kg and 1800 x 1000 x 1000 mm, the set is arranged on a forklift-friendly chassis, which matters for rental companies that redeploy equipment between sites.

Typical Applications

• Construction sites — powering tools, temporary lighting and welfare units where grid supply is absent or unreliable.
• Rental fleets — a mid-size set that covers a broad share of commercial and light industrial demand.
• Agriculture — irrigation pumps, grain dryers and small processing lines.
• Events and hospitality — silent running makes it practical for outdoor venues, food service and market stalls.
• Small industrial standby — covering control systems, motors and lighting during grid outages.

Export Handling

Units are tested in the GOBIZ workshop before delivery, and the team handles loading, worldwide shipping by road, sea or air, and all export documentation. Multi-brand stock is available, and each machine comes with a personal advisor who follows the order through to dispatch.

Why the 22 kVA Class

Choosing a set slightly larger than your calculated peak load gives headroom for starting currents and future expansion without a jump in fuel use. At 22 kVA standby in a silent canopy with ATS and a 65 L tank, the GBP-22 covers a wide range of professional uses at a size that remains easy to transport and install.
