Re: Yamaha 2000i's in parallel
Ok, so the 44260 gives minimum surge protection while letting voltage variations through to the voltage regulator, and if you get a surge that passes through the 44260, it will possibly fry the VRSG but the 44750 or the 34830 will protect your tt. It seems it would be better if the 44750 or 34830 would let through voltage variations to the VRSG and then you wouldn't need two surge guards. About your circuit board, maybe you can find someone third party that could repair it at a reasonable cost. At work, we've had some fried components on our automation boards and found someone to rebuild them cheaper than the manufacturer or replacing it. I'll look up the company. It won't be until next week though, I'm on vacation.388Views0likes0CommentsRe: Yamaha 2000i's in parallel
SoundGuy, Now you've got me looking at surge protection and voltage regulation. Looking on the TRC site at the pdf for the 30 amp VRSG, it states I need surge protection before AND after the regulator. Is this overkill? It would seem the surge protector upstream of the VRSG would be protection enough. Am I missing something?388Views0likes0CommentsRe: Yamaha 2000i's in parallel
wa8yxm, I posted this earlier today. Thanks for your reply. OK, I tested them again today. No problems. I let the A/C do it's own thing through 4 cycles and all is good. I started with 125.6 volts, the fan kicked on and then the compressor, initially dropping to 115 and leveling out to 120.4 or so. When the A/C kicked off on normal stop, the voltage didn't spike, it returned to normal. Only thing I can think of, and I don't know if I did this or not; or if it would affect the situation. I made a point of it today to hook up the parallel cables before I started the generators. I can't really say if I did so the other day or not. Otherwise, set-up and run conditions were the same. I'll keep y'all updated, and thanks for the help. One question though, in y'all's experience, is there a power management system that would boost the voltage if I find low voltage at a park, and would also act as a surge protector, or do I need separate devices?325Views0likes0CommentsRe: Yamaha 2000i's in parallel

Hey SoundGuy, thanks for the reply. In my research, I'd never run across the problem with the sine wave, thanks for that information. I don't have a power management device but was considering a Hughes Autoformer. The A/C does have a hard start and the fan comes on first, then the compressor. The units take the load, they will even reduce rpm's after the initial hit, it's when the load drops off is when the problem of overload arises. The A/C compressor will shut down normally, the fan is still running and the generators rap out. The units don't shut down, they just go off line. I'm going to test it again tomorrow. When the A/C kicks off, the display on the microwave starts dimming so I don't know if the problem is with one generator tripping first and then the other overloading or if the whole gen system gets overloaded at once.328Views0likes0CommentsYamaha 2000i's in parallel
HI y'all, I'm new to this site and new to rving. I have a 2016 R Pod and would like to boondock. I bought two Yamaha 2000i's (after a lot of research) to run my TT. They will run my Dometic Penguin 2 13.5 btu a/c but when the a/c cuts off, they speed up and go off line on overload. I've run them with the economy switch off, and with it on. I first ran them with it off and they went down when the a/c cut off. When I ran with the economy switch on, they took the load just fine and then ran at approximately 1/4 to 1/2 speed. I thought this would work because it would give them room for more speed once the a/c cut off. Nope. Any suggestions? I've done so much research before I bought these units but have not heard of this problem. Is there something I can add to bring the load down slower, or is there something possibly wrong with the units? Your input is much appreciated.4.4KViews0likes29Comments
