Hyundai 5.2kW Silent Standby Diesel Generator DHY6000SE

The Hyundai DHY6000SE is a 5.2 kW silenced diesel generator specified for standby duty — a machine that sits idle and is expected to start and carry the load when mains power fails.

Standby is a specific rating, not a description. A set rated for standby is permitted a higher output than the same machine rated for continuous running, because it is assumed to run for limited hours. Sizing a standby set as though it will run continuously, or the reverse, is how generators end up either tripping under load or wearing out early; our guide to standby, prime and continuous ratings explains the distinction.

The acoustic canopy matters for standby in particular, since the machine is usually installed close to the building it protects. See noise and acoustic canopies for how to read the figures. Tell us the circuits it needs to carry and we will confirm the rating with you.
