Description

FG Wilson P55-3 Diesel Generator – 50 kVA Prime / 55 kVA Standby

Manufactured by FG Wilson (Caterpillar NI Ltd.) in October 2015, the P55-3 diesel generator offers dependable power with a prime rating of 50 kVA (40 kW) and standby rating of 55 kVA (44 kW). Built in Larne, Northern Ireland, this generator is powered by the robust and fuel-efficient Perkins 1104A-44TG2 engine—4-cylinder, turbocharged, 4-stroke—with a mechanical governor and direct injection system.

The alternator—typically from Leroy Somer or Marelli depending on production—is brushless, self-excited, and equipped with an automatic voltage regulator (AVR) such as the R220 or DSR. With insulation and temperature rise both rated Class H, and protection to IP23, the alternator maintains voltage within ±1% and limits harmonic distortion to below 3% on linear loads.

Rated at 400/230V, 3-phase, 50 Hz, and running at 1500 RPM, the P55-3 is controlled by FG Wilson’s PowerWizard 1.1 or 2.1 digital module with an LCD interface for real-time engine and generator diagnostics, fault alarms, and remote start/stop capability. It includes standard protections for overspeed, oil pressure, coolant temperature, voltage anomalies, and more.

Fuel consumption is approximately 10.2 L/h at 75% load under prime operation. The generator is typically equipped with a base fuel tank ranging from 100–150 litres depending on the canopy configuration.
