Choosing between MAN E 0834 E302 and PSI 6.7L

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 PSI 6.7L has the higher headline kVA rating in this pair, but site conditions and duty cycle can still change the final recommendation.
