Noise Level (dB Rating)

For home use, aim for:

Very quiet operation (50-65 dB at 7 meters)

Fully enclosed acoustic canopy

Power Output (kVA/kW)

Small homes: 5–8 kVA

Medium homes: 8–12 kVA

Large homes: 15 kVA+

Overloading is the result of buying too small, while the other extreme wastes fuel: that’s just wrong.”

Automatic Start (ATS Compatibility)

An Automatic Transfer Switch enables the generator to start during power outages without manual intervention, so it's highly recommended for residential use.

Fuel Tank Capacity

Bigger tanks use longer battery time, which can be helpful during long outages.

Ensure the generator:

Meets UK/EU emission standards

Has proper weatherproof housing

Comes with a manufacturer warranty
