[Vwdiesel] Chinese diesel gensets?

In your application I would shy away from a new Chinese diesel plant for the 
reason that you don`t have someone who will be available and willing to 
constantly tinker with it like a hobby engine until all the bugs are worked 
out of it.  If budget is the reason you are thinking Chinese get a used 
North American made plant on ebay that has been used gently (just a few 
hundred hours) as a back up in a telco installation or institutional 
setting.  Grab one if possible that has the transfer and control panelboard 
included.  Onan, Kohler and Kato or Katolight are good names. Marathon makes 
a very good generator head (alternator).

In your application you might be able to use natural gas instead of diesel. 
If so, this really opens up the assortment of available gensets that will be 
available to you.
