Magnum Hybrid MSH4024M advice

[Dave5Cs]

It was  lightning we were in it at the time and couldn't figure out why 1 AC went out and the other was still working. When the storm was over I went up on the roof and there was about 2 inches of wire uncovered before it went into the plastic tube to the AC. A big burn spot of the roof and the Hot wire was hit and broken apart. We heard it felt it and saw it. The inverter was fine and still is.

Geoff, I thought the MSH40204M is just that?

Keep in mind that these units don't like AFCI and GFCI - FWIW

[Dave5Cs]

 Scott yes it is a pass through type MSH 4024 Hybrid

Niles,

You mean if I plug into a GFCI outlet it will trip it? I've had that happen already with adapters from 50amp down to 20. Always a bummer.

I have four group 31 deep cycle 12v batteries.

Scott, if the bus is wired properly and the inverter is installed correctly then no, you will not have issues with plugging into GFCI outlets. I do it often.

Scott, the problems i' m referring to have to do with the internal transfer switch relays. If the relays don't switch precisely together the AFCI or GFCI will see a fault. Not just Magnum, but any inverter that uses an internal transfer switch. This momentary fault is not a problem with standard breakers as it occurs for only milliseconds. I only mentioned it because you noted you spent a lot of time on 15/20 amp circuits which are more likely to be AFCI and GFCI protected - HTH

I set up with the 24 volt battery bank so the amp draw was way less and the coach could charge the batteries as we drove . then I used a step down 24 volt to 12 volt system for all the 12 volt stuff . all worked great . I even would use the split unit a/c when driving off the inverter and not have to turn on the genny

I had to install a small 12 volt battery in the system for any large amp draw ( my slide out motor ) but got away with a 12 volt lith . screw gun battery .

again I wish the Featherlite was set up like this but I do not want to reinvent the wheel to get it

The only time I have EVER had an issue plugging in to a GFCI outlet with the bus was in my early bus years when using low dollar china products. I had a xantrex in my previous bus, as well as a similar model xantrex in my current bus, and a year ago switched to a Magnum. None of the three units had any issues plugging into a GFCI outlet. I will say it again, if the installation is done properly you should have no issues plugging into a GFCI outlet with the inverter you are interested in.

Thanks niles and Derrick. Good to know and good to know...

Dave, I'm getting the 24 volt unit but it should still provide 12 volts on the house side right? Please tell me it does.

Usually, a Vanner equalizer is used for this need in addition to your inverter. If you have only light loads, there are several voltage reducers available. I use a Pyle for my King cruise control, pulse wipers, and lighter socket for electronics, GPS, phones etc.

[sledhead]

yes
12 volt for your house stuff . you should be fine with the converter link I put in the other post .

I already have twin vanners installed on the coach. So just tap the 12v from those and call it a day then?

[sledhead]

yes
but are the vanners on the bus side or the house side of the battery bank ? or do you only have 1 battery bank for all ?

On mine, it runs off the coach start batteries.
