Madden 6.5 kW Silent Long Run Standby / Backup Diesel Generator MAGE8500

The Madden MAGE8500 is a 6.5 kW silenced diesel generator with a long-run fuel system, specified for standby and backup duty.

Three things are being bought here together: diesel for fuel economy over long hours, a canopy to make the noise tolerable near an occupied building, and an extended tank so the machine runs through a shift or overnight without refuelling. For standby duty all three matter, since the set is usually installed close to what it protects. Our guide to noise and acoustic canopies covers how to read canopy figures.

Standby is a rating, not just a description — a set rated for standby carries a higher figure than the same machine rated for continuous duty. Getting that wrong in either direction is the most common sizing error we see; see standby, prime and continuous ratings, or send us the load and duty and we will confirm it.
