3000W Chinese Gensets Info.

Also professor can you check these 2 generators out for me and see if you can tell the differences between the 2:

There are 2 6.5hp 3500 watt generators, they look different and appear to have different receptacles and 1 is more than the other. Cna you tell me if one of them is RV ready?

I can't tell you anything about the model 3500R other than what is posted on the web site. I do not recognize the unit as one I am familiar with.

The Model 3500 is a JungDong built generator with the same design and features as the original ELM3000. It has two 120 volt outlets and one 220 volt outlet. The unit has a switch that will allow you to select full wattage out to a single 120 volt outlet (in this case, both 120 outlets are parallel). I own one of the original ELM3000/JungDong units and have been very pleased with it. Buit, we did have some reports early on of ELM3000/JungDong units pooping out early in life and having to be returned for repair or exchange. An ELIM International engineer once told me that this is the reason they switched from JungDong to Lunatop generators for their product line.

Neither unit is "RV READY" in respect to connections. Either one would need an adapter to mate the standard 120 outlet to the TT 30 amp outlet. While the RV Ready feature is convenient, it is not necessary to have one designed with a RV plug to get reliable service with a 30 amp camper connection. Adapters work very well in most cases and are less than $10. What is important is having all available wattage routed to a single 120 outlet (without having to rewire).

As far as brush vs. brushless, there have been several discussions on the pros and cons of either design. The plus side is a brushless unit had fewer friction wearing parts, while a brush type unit may eventually need some replacement brushes. Brushes also are know to arc, sometimes casuing noise in sensitive electrical appliances. But, again, I have no reports of this being a problem on these units.

On the plus side the units with brushes (or slip rings) appear to have a more complex and accurate voltage regulation unit, while those that are brushless are using an AC capacitor and diode for regulation (not as accurate).

At this point, I personally do not believe brushes vs. brushless is a decision making factor in your selection of one of these generators. Both are good designs and either one should give you acceptable service.

I have no idea what PowerPro has planned for the future as far as a unit with a RV outlet. But, I "suspect" that the market is well aware of the volume of these units that are now being purchased by the RV community. If they see it as a desirable sales feature, it will eventually be added to additional makes and models that want to remain competitive in this area.
