Choosing between SDEC 6HTAA6.5-G23 and VMAN C07A

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 VMAN C07A has the higher headline kVA rating in this pair, but site conditions and duty cycle can still change the final recommendation.
