I'm sorry to bombard all of you with Q's, but better ask than learn from my own mistakes. I did do a search, but couldn't find exaclty what I was looking for.
I have one of these
1) What voltage is "too low". I read somewhere between 105-110v is the threashold for some people.
2) When I connected my generateor (Yamaha EF2000IS)and run it, It shows "GF", which means open ground.... What am I doing wrong here to cause this reading? I have generator sitting on the ground, 15 to 30 amp adaptor, and factory 30 amp cable going to the AS. There is a "ground earth terminal" on the front panel, which is the bolt/nut sticking out. Do I need to connect this to anything?
3) I "tried" running the AC on low fan on generator with everything turned off on AS. It's a 13,500 Duo-therm AC. It ran fine for about 5 minutes and I had generator on "economy" mode, and it wasn't even revving up much. Then all of the sudden it revved up and "overload" light came up so I stopped it. I've heard of conflicting stories about running AC on low on 2000w generator. What if I ran on "reg" and not "econ" mode which revs pretty high?? I didn't get the generator to run AC (perhaps in the future running parallel"), but is experimenting like this bad for the gen./AS?
4) Lastly....does anyone use 30 amp surge protector when you hook up?? They are somewhat expensive and wondered if it's essential. Thank you all for the input.
