Choosing between Caterpillar G3516H and Guascor G-86EM

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 Guascor G-86EM has the higher headline kVA rating in this pair, but site conditions and duty cycle can still change the final recommendation.
