How to Choose a Generator for a Hotel or Guest House

What guests notice first

Air conditioning, lights and Wi-Fi are the three things guests complain about most during an outage.
The generator should cover these first, then the kitchen, then the lift if the budget allows.

Load estimate by hotel size

Guest house with 6-10 rooms: lighting, sockets, AC and fridge: 9-12 kW.
Small hotel with 15-25 rooms plus a lift: 15-18 kW, or a larger set if the kitchen is electric.
If cooking and water heating are electric, the load jumps sharply and must be calculated separately.

Noise is a commercial decision

Guests will complain about noise long before they complain about power quality.
Always choose silent type: our sets run at 70-75 dB(A) at 7 metres.
Place the set away from guest rooms, and if possible behind a wall, with the exhaust facing away.

Installation essentials

Use an automatic transfer switch so the changeover happens without staff intervention.
Fit anti-vibration mounts to stop noise travelling through the building structure.
Keep a maintenance contract; a failed standby set during high season costs more than the service.
