Not Charging: Inverter & Transfer Switch Location

I am looking for the inverter and transfer switch location. I am hooked up to 50 amp shore power and the Magnum Energy display is not showing any battery charging at all. I turned on the generator and same issue. No electricity at all. I am currently using the inverter but the house batteries are not being charged and I will lose power soon.

I need to check the inverter and transfer switch to ensure the breaker is on or other issues but can't find it.

The load meter has a green light on 50amp and all green lights on right.

Help! I am currently at the RV park but need power ASAP.

Thanks!!

The inverter is normally located up between the chassis rails. You have to crawl in to the basement and look upwards. If you follow your power cable it should go directly in to the transfer switch. But the transfer switch defaults to the generator so if that is not getting to the coach I doubt that is the problem. Have you checked that the generator hasn't tripped?

Another thing to check is the fuse between the inverter (charger) and the battery bank. My KGDB takes this one: https://www.amazon.com/gp/product/B000MMH1J4

He posted that he is running on inverter power now, so that fuse has to be good or that wouldn't work.

Not if he's on shore power or generator and the inverter has a pass-through mode (internal transfer switch). And he says he's on shore power.

Been there, done that.

I agree with what you say. I guess I'm getting a different message from his post than what you are.

Agreed. Not enough details in the problem description.

On my Essex, the inverter is located in the bay just forward of the wet bay, door side, up between the chassis rails. Not much to see there related to charging, except to verify incoming ac power. If you are on shore power, then the inverter should not be in use.

Verify your inverter breaker in main breaker box. Also, while on shore power, turn off the inverter and verify ac power outlets...tv, refrigerator, etc.

UPDATE:

The inverter is fried. The tech stated that the internal converter switch is not working in the inverter when hooked up to shore or generator power, therefore the coach does not get AC.... which cannot charge the batteries.

I did get some AC from the shore power but it only powered the HP but not charging the batteries. At least I got heat.

Need to replace the converter. Grrrr. :-(

The magnum MSH3012 is a popular replacement. I've had one for 18 months.
