I checked the output of my generator and it is 140v, is this too much?

I had a long discussion with Xantrex yesterday, first thing discussed was the humming from the Inverter, they told me this is normal while charging especially if the batteries are low. As they charge the humming gets quieter, so I just went outside to listen and although there is humming it is a lot quietter. A friend came over and measured the voltage on the Inverter out put and it was 121. The voltage from Inverter has to be done with a True RMS meter not a regular meter. Those meters run about $120 bucks, I'm cheap. So if it measures around 94 on a cheap meter it is good. So to all who are reading this would you do me a favor and those of you who have a Xantrex Freedom 458 2000 could you see if your Inverter is humming while charging your batteries and let me know if you hear anything. You'll have to open the compartment the Inverter sits in to hear it. I just checked mine while writting this and I had to open the compartment to hear it humming. One last thing I'm doing today is to clean all the battery terminals/connections and check the output of each of my 4 6v batteries. Then I'm going to put it all back together and relax. My batteries were purchased in August 2017 from Sam's Club at $90 bucks each, Duracell 6v Golf Cart batteries. Too bad there isn't a Sam's Club in Saint George, Utah. So let me know if your Inverter hums, thanks for all the input and suggestions and if any of you are ever in Saint George, Utah and need help on your Motor Home, give me a holler and I'll give you a great Diesel repair facility and a reasonable Mobile RV Tech contact.

So any thoughts as to the loud humming from the Inverter?

The Inverter saga continues. Tech showed up today and checked ac power coming in to the inverter, it's good. The Inverter is humming, the Tech suggested when I took the 4 6v batteries out to be tested I put them back in the wrong place. For example if the batteries were marked 1/1 and the one behind it was marked 1/2 and the other two were marked 2/1 and the one behind it was marked 2/2 when I took them out to be checked and was told all 4 are good and I put them back into the MH I put 1/1 in front of 2/1 and 1/2 in front of 2/2 the batteries were not used to working together and this could be why I'm getting the humming noise and less then 120v on my meter readings when the inverter is turned on. What do you think Wolfe10, does this sound plausible? When I disconnect and remove my batteries I always make a drawing and as each post is disconnected I mark and secure the cables together off that post so I know where they go when I put the batteries back in. This time I will mark the batteries as to which side and front or back. I also have one battery that takes a lot of water (distilled) each month when I check them. He thinks this might be a bad battery. So I'm going to disconnect and remove the batteries tomorrow and let them sit (on wood) until Monday or Tuesday and then have them checked to see if each is putting out 6 volts. These were purchased on 14 Aug 2017 at Sam's Club. They are Duracell 6v GC2 Golf Cart batteries made in the US.

Well the Tech didn't make it yesterday he had a MH where it had been attacked by Rats. He's trying to locate and rewire all the chewed up wires. I found on You Tube some info about the battery Temp control wire. Xantraex says to remove it from the battery terminal and fasten it to some where else in the battery compartment. Seems it could send a false signal to the Inverter. This must be why when I got the new Inverter there was a new Temp control wire sent with it. I'm not touching anything since the Tech shut down all power on last visit. I told him about this and he thinks this might be what caused the old Inverter to fry one of the boards. We'll see next next Thursday on the 13th, hopefully it will be my lucky day.

The Tech showed up today and found the bathroom GFI was wired wrong. That would be me. As far as the Inverter power there are some questions he will be asking Xantraex and he will be back on Thursday afternoon. He is also thinking that perhaps National did not wire the fridge plug to the Inverter. His Grandfather's 2001 Dolphin (National) is not wired for Inverter. Stay tuned for the Inverter Saga Thursday.

Too bad you all are so far away, it would be fun to have you all checking this out in person. Hang in there until Tuesday after noon.

Thanks, I'll just try to kick back and wait for the Tech to come and check it all out. At least I know my shore power is good.

Shore power is 122 good or bad??

Thanks for the heads up on the 140. Every thing was off except the genny. I'll just leave it on shore power until the Tech gets here. Gee I was happy the generator showed 140, see I told you all I'm kinda DUH to electrical on this MH. A little later I'll post the shore power and then you all can tell me if it's good or bad. Love this forum site, really get good advise/responses.

Thank you to all of you who have responded, really appreciate it. For now I'm going to wait until Tuesday and see what the RV Tech has to say. I will share all the responses with him. I'm not too good with electrical so I'm going to let him hunt down the problem. That new Inverter was just over a grand and I don't want to have to replace it so soon. I did run the generator yesterday to let it exercise and I checked a few outlets to see what voltage was being put out. All of the plugs tested showed 140, even the fridge plug and the hummer GFI did too(only hums on Inverter). I'll have him check the ground.

It only hums on the Inverter. No hum on shore or genny power.

I bought and installed a Protect-a-tow in November 2011 when I purchased my new 2011 Honda CRV, todate there are no dings on my CRV after 8 years and the rear of the MH does stay cleaner too.

I have not reset the breakers. As to the other circuits, the whole drivers side plugs are now working and the tv's are working and on the passenger side the microwave is also working. The GFI above the bathroom sink is also working off the inverter except it puts out a humming noise. Is this common?

The tech who installed it will be over on the 4th. I watched him mark the old wires before he changed out the Inverters. Is it possible when he was setting the battery type for charging that he set it to the wrong type of battery. Would this cause the Inverter to not be able to send power to the plug?
