All;
I need a bit of assistance here.
After the ice storm we suffered last week; I picked up a "GG3500" Genset from Pep Boys. It is badged as a "UST 3500 watt"
I recently posted the following:
Other major manufacturers of these small generators are:
Shanghai Chenchang (UST, Contractor, and many 1,000 watt 2 cycle units)
Taizhou Zhongshan (Direct sales in small quanities to most any buyer Big Lots, etc.)
Fuzhou Hauccen(Power Pro)
Jiangsa Jiangdong (Allpower, early ELM3000, Wildfire, Harbor Freight)
The UST is almost an exact feature-for-feature copy of the units made by Jiangdong (i.e. Early ELM3000).
It does not use an AVR. The capacitor serves as a crude but effective voltage regulator in the exciter winding. There will be more noise on the AC wave from this type of unit than those with a solid state AVR. This usually only has an impact on synchronous devices that use line frequency as a clock (microwaves for example) and older ferroresonate converters. Otherwise, equipment in your RV should power from the UST just fine.
Others on the forum who have purchased the unit report that there is no problem running a 13.5K BTU AC.
Like my early ELM3000, tech support has pretty well disappeared. As long as it keeps working, you are in great shape!
