Has anyone heard anything about these units:
Roybi 2000 Superquiet Generator
...it seems a little more price competitive than Honda and Yamaha...thoughts?
Its kind of comparing oranges and seedless oranges; the difference is the pits.
From a rough read on the web about these units they seem OK though they do not have a operational history like the Hondas and Yamahas. Whether they are as mechanically sound as Red or Blue we will have to wait until that history develops.
The huge reason they are cheaper is that they cannot be paralleled. Both Honda and Yamaha can be paralleled which allows them to deliver almost 4KW.
Ryobi's own literature does not readily lend itself to comparing these "oranges." On the db ratings, Ryobi seems to use a more realistic power setting, but this makes it more difficult to compare fuel consumption to seedless varieties available.
I may have missed it, but I did not see if the inverter is a PSW or MSW. I am assuming it is using at least a PSW inverter or they would not be retailing for $600.
Other than reliability
, these types of gensets are probably OK as long as you are OK not having a parallel option. It still, buyer beware, but I would also be aware that there are other manufacturers that manufacturer similar units, and priced in the same range as the Ryobi, with a longer track record.
