parallell connection of generators

Thats right Tony.
They also have to have the "Honda receptacle box and cables" for parrallel operation.

Not sure what these other blokes are on about with their tales of large diesel engine gen sets going bang though.
I used to work in a diesel power station too & thats got nothing to do with small modern Hondas with electronic synchronising and control.
Stop big noting yourselves & give relevant info fellas.

I agree - you can’t compare paralleling large non inverter type gensets - with the portable inverter type. I seen the big ones synchronized but not the portables. If it’s a quality unit like a Honda or Yamaha and you follow their specifications - I’m sure you won’t problem.

Yep this sounds correct.

I asked our electronics guy at work about this some time ago. Apparantly the hertz (cycles) have to be perfectly syncronised or one of the generators will self destruct. It appears that you have to do this with some clever electronics in order to prevent a serious failure.

I am by no means an expert on this but thought I would let you know what our expert said to me when I asked him.

Different sizes can be parallel. If you consider our national power grid every power station has different size alternators and they are all syncronised. As Stu mentioned the frequency must be the same and the peaks of the wave MUST be occurring at the same time, I.E. synchronised. Long be for the sophisticated electronics this was achieved with 2 lamps and 2 volt meters. When the brightness of the lamps and the volt were correct the switch could be closed with out risk of damaged. The maximum damage as descibed by Fred happens when they are 180 degrees out of phase or sync; a bit like connecting 2 batteries reverse polarity, something has to give.
