Electric trouble. Inverter?

Hello, all. For the last 6 or 7 days we would lose electric power for unknown reasons. I cycled the circuit breaker on the power pole and all was well for the rest of the day. Today after parking near Bella Vista, AR, it happened again. This time, both air conditioners worked and about half of the 110. Flipping the breaker on the pole did nothing. Got to looking at the inverter and the green light was going on and off. Had a problem with it 5 years or so ago and had to reset something, don't remember much about it. I then shut the breaker for the inverter off, and everything started working again. Any wisdom from this wise group would be appreciated.

Al/Barb, we need a bit more information. What type of inverter do you have, a 2001 coach could very well have had a replacement over the last 16 years. When you shut off the inverter it goes into a bypass mode, effectively sending the 110 volts directly to the plugs. That, along with the green light going on and off, would suggest that you have an inverter issue. Your A/C units do not run through the inverter, about half the 110 in the coach does. Bottom line, it sounds like you do have an inverter issue, need the make and model of that inverter.

The inverter should be a Freedom 2000 that is what WRV installed in 2001.

Onan Inverter

The Onan Equinox Inverter on my 05' Avalanche kicks off all my 120 when we use the Microwave while the Roof air is running. It is mounted in the middle of the basement back wall...very unhandy to reach ! Is the inverter Faulty and in need of replacement ?

Roof AC shouldn't have anything to do with inverter or microwave ops--microwave is pretty heavy load for a 2000 watt inverter but should handle it if batteries are in good shape/ good-clean shore power-- if both good, sounds like you have an inverter issue. The Equinox inverter was used by WRV for only a short time and proved to be very problematic--most owners have had to replace these units long ago.....

Are you plugged into 50 amps? Or 30? Shore power.

Dubya, please confirm the information in your profile, do you have an Avalanche (do you have a rear radiator)? WRV manufactured a very limited number of Avalanches and in order to reduce costs did many things differently on the coach.

Are you running on 30 or 50 amp shore power?

Does it do this when you are on generator?

Do you have surge/power protection (like a Progressive Industries unit) installed either permanently or temporarily?

As old scout says the A/C does not run off the inverter, however with surge protection they could be related, or if you are running on 30 amps. We need more info to help you further.

Old Scout, The inverter was damaged by the accident...the breaker handles were broken off. What brand of inverter would you recommend as a replacement ?

Dave, Yes, I have a 2005 Avalanche with a Rear Radiator. The problem only happens at parks with 30 amps power. I hardly ever use the Genset. I'm not familiar with the progressive industries unit. Now that I think of it, our last trip was at a Campground with 50 amp service and even running Both AC's, no problem ! Thanks to you and Old Scout !

Can't really offer a personal recommendation on a replacement inverter. Magnum seems to be a pretty popular brand. They offer both 2000watt and 3000watt models--the 200watt seems large enough to me. Although I own one, I've never been real positive about Xantrax products, though they did buy out Freedom several years ago so maybe their product line has improved. I will recommend that whatever inverter you get should be a "pure sine-wave" model as opposed to a modified sine-wave.

Wayne, I suspect the problem might not be your inverter, but rather the 30 to 50 amp "dog bone". When you are plugged into a 50 amp pedestal you actually have two 50 amp circuits giving you a total of 100 amps. When you run on 30 amps the dog bone puts 120 volts (a total of only 30 amps) to both of the two 120 lines in the 50 amp plug. The microwave runs off the inverter, that plus the inverter load and 1 AC unit (you should NOT try to run both AC's on 30 amps) will max out a 30 amp pedestal breaker.

I am thinking the dog bone may be no good, try another one and see if you still have the problem before you replace the inverter, broken breaker handles should not mean you have to replace the whole thing, just replace the circuit breaker.

As far as a recommendation for an inverter, I hear the Magnums are very good.

Al, the old Heart inverters have round (button type) circuit breakers. If it is tripped, press the button to reset. Intermittent problems can be very hard to troubleshoot. However, don't be surprised if your inverter is about to go south for good. As other have said, the AC's are not powered through the inverter. Two winters ago, I replace my old inverter.
