Choosing between MAN D2862 and Mitsubishi S12R-PTA-D

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 MAN D2862 has the higher headline kVA rating in this pair, but site conditions and duty cycle can still change the final recommendation.
