A 50 kVA set typically powers clinics, restaurants, workshops, small warehouses, farms and construction site offices.
A very common standby size in the UAE: pair it with an AMF controller and an ATS so the building switches over without anyone on site.

Frequently asked questions
About 40 kW of running load at 0.8 power factor. Keep 20–25 % headroom for motor starting and Gulf heat — in practice roughly 32 kW continuous, for example around 13 split AC units of 2 tons, or the equivalent mix of lighting, pumps and equipment.
Roughly 5.6 L/h at 50 % load, 7.8 L/h at 75 % and 10.8 L/h at full load. Exact figures depend on the engine model; we include the manufacturer's fuel curve with every quotation.
Full-load current at 400 V three-phase is about 72 A, so a 100 A ATS is the usual match — or the main incoming breaker rating if that is larger. A 4-pole ATS is recommended where the generator neutral is separately earthed.
It depends on the engine brand, enclosure, controller and whether you need an ATS and fuel tank. Send us the site and delivery city on WhatsApp and we reply the same working day with 2–3 engine options side by side.
Standby (50 kVA) is for emergency backup with limited annual hours. If the set is your main power — a construction site or an area with daily outages — size on the prime rating (about 45 kVA for this set) or choose the next size up.
