    hahaha. ok so the readers will know not by assumption, here's the computation.

    since all of boybi's load are pure resistive, then boybi has an inductive load. and since most of it comprises motors then i will put a conservative number for power factor of 0.86

    total connected loads is around 28000 watts.
    total power factor 0.86

    therefore; kva=watts/1000 x power factor
    = 28000/1000 x 0.86
    = 32.5 kva

    and that is full load. if we apply 80 percent utilization then,

    our kva (new) = 32.5 x 0.8
    = 26 kva

    that's is why i say 30kva is enough.

    one most important thing. do not buy chinese brand. the cables and cores were mostly made of inferior materials like aluminum not copper. and when the generator heats up this materials will deteriorate faster. this is the reason why chinese will advise the buyers to buy the next higher because they know their product won't last long.

    by the way, i don't care if others burn their money. its not mine and i don't care hehehe. this is for the readers. buyers who will opt to choose chinese brands, better add 10 kva to compensate the heat loss.

    again hope this help.
