Inverter Question

[jauguston]

The OP also was a great example of how to come to a public forum and act in a way that will likely make sure no one will help him if he shows up again.

Let's give a newbie the benefit of the doubt. I hope he will return and add more information to his initial post.

Maybe he actually thought he would get help instead of people trying to impress with their degrees and where they worked. Apparently everyone on here knew EVERYTHING when they first started out. It was his first, and probably last post on here.

Wow, what a thread.........

Yeah, I really should apologize in my part of all this. I have to get really annoyed to mention working for NASA. It actually was the least favorite job I have had. After I returned home from overseas I worked in maintenance at a chicken processing plant for a while. It was fun and I designed some Programmable logic computer operations to get them away from their manual modes. It was fun and non stress work but it just does not sound impressive to say you worked for a chicken plant. I noticed the original poster did not come back. I am not sure whether that was because they got the information they wanted or they got scared off by the non topic posturing that I at least was doing. The other poster George seemed to learn something new from his comments. I also learned that units that provide AC from batteries and also use shore or generator power to charge batteries should be properly replied to as inverter/chargers. No one is too old to learn or make the effort to correct bad habbits. Once again for my part in this I apologize.

I am sorry what is the topic? As someone else has already said the OP has probably already left this discussion.

Kudos to anyone who will take responsibility for their actions and appologize for their actions.

hi, we have a 2006 holiday rambler endeavor. Our surge protector was not making a good connection at the power receptacle. I called a rv tech and he got it working right again, however while he was out there he said he reset our inverter. We left the park and went to a new location, when we got there our batteries were too dead to put our our electric or door awning. I went out to the inverter and on the right side is a button. I pushed it in and a green light went on, voila, the tech must have turned off our inverter. No problem anymore. Sometimes people are more hinderance than help.

Hi, sorry for the tardy response I was on vacation. My coach is a 2004 Holiday Rambler Endeavour, my inverter is a Magnum ME2012. Please let me know what more info I can provide and thank you all thus far for the input.

Ok lets see if we can give you some pertinent advice

1. There was some advice postings earlier have you tried any of that. Here is the manual for your inverter http://www.magnumenergy.com/Literature/Manuals/Inverters/64-0002%20Rev%20A%20(ME%20Series).pdf

Operation starts on page 45 page 48 tells how to reset the unit in the rare event you have to do that.

My advice is going to be first download and keep a copy of the manual. It will be something that will come in handy in the future. Second of all make sure the power switch is on see page 45. There is a notation in there to turn it on after you change batteries and I noticed in your original post that you mentioned you had new batteries. The unit appears to charge the batteries while it is off ( in what they call standby mode) and will not perform the inverter function until you turn on the on switch. Try that and the reset and if they do not work and you need help with the troubleshooting section post again and we can try to help you. If you do find it please post what it was so others can have it for future reference.

In a foot note. I did notice in your manual that it shows you have a transformer and rectifier circuit to make DC not a switchable power supply at least according to the diagram on page 46. One of the earlier posters felt that most companies have started using switchable power supplies instead of transformers and bridge rectifiers. Evidently magnum still uses them and If I had to guess and it would be a guess is because it is cheaper and possibly the transformer and bridge rectifier is more reliable at the higher currents involved but I do not know enough about switchable power supplies to know if my guess is reasonable. Good luck with your troubleshooting and let us know what you find.

I had a problem with an inverter a couple of months ago. I did a quick troubleshooting check and decided the inverter was bad. I took it to the shop to get it fixed under warranty and they found out I had a broken wire going to an outlet the dealership had put in to plug the chassis battery charger into. Since the outlet was not put in by the factory the warranty did not pay for the repair. The repair shop took the outlet out. Used two wire nuts to connect the wires and charged me 350.00. A little bit more troubleshooting on my part would have saved me some money. If turning it on or resetting it does not fix it then hopefully we can help you at least make sure that it is not a simple broken wire.

I'm sure this little tidbit of misinformation was directed at me as a result of our previous ridiculous discussion. The term is "switch mode power supply" NOT "switchable power supply", (whatever that may be).

Switch mode supplies do have power transformers as rectifiers, but they also have sophisticated inverter, clipper, switcher and filtering stages that are included in that little box you chose to ignore, labeled F.E.T Bridge. Thus, the term "Switch Mode". I assure you, the Magnum ME series has a very modern and reliable SMPS as the heart of their charger.

That basic diagram you referred to, depicts nothing about the actual design, complexity and versatility of the multistage battery charger in the Magnum ME Inverter/charger. It was purposely kept simple to avoid confusing the less technical among us.

WOW !! now we all know who has a BIGGER puffed up chest !!
Nothing like a bunch of old guys remembering what they used to know.

Just the other day I was explaining to my grandson about boulean algebra and the computers I help develope on which Bell Labs created UNIX. but that was 1968 and a lot has changed . LOL

thanks for the long explanation of how I charge my batteries.

You hit the nail right on the head "old guys remembering what they used to know", at least one of them apologized for getting "wrapped around the axle"

I'm a maintenance type and at one point worked for an Electrical Engineer. I gave him a bumper sticker for his car, but he refused to put it on his bumper:

I have a Magnum Device that does the work of a converter and a inverter. It will charge my batteries at up to 100a and provide 2000W of msw AC power.
When someone asks what I have I call it a converter/inverter combination in one unit. Is that a proper description? It seems to be a fine unit and on the AC side there is nothing in our coach that it won't run.
