Choosing between Generac SG450 and MAN E 3262 LE232

Use this comparison as an engineering shortlist, then confirm the complete generator package against load profile, voltage, 50/60 Hz frequency, duty class, emissions rules, cooling margin, altitude, ambient temperature, enclosure design, controller features, and alternator sizing. The Generac SG450 has the higher headline kVA rating in this pair, but site conditions and duty cycle can still change the final recommendation.
