Maximum 60 amp inverter

09 Safari Simba. I have a Maximum 60 amp inverter. I have yet to find an outlet in the MH that runs off this inverter. The breaker switch and the switch on the inverter are the only switches I have found. It appears that the romex yellow covered wire from the inverter goes to just one outlet in another storage compartment where the converter is located and pluged into. Is it likely that the sole purpose of the inverter is to charge the house batteries?

Thanks !

Not likely. That scenario is one that inverter installers have to avoid.

The batteries, powering an inverter, inverter powers converter, converter charges batteries. This is a cycle that will eventually drain the batteries because of the efficiency losses in the converter and inverter.

Are you sure it is an inverter and not a converter? The "60A" rating makes me suspicious. An INverter is rated according to its out watts @ 120v, whereas a CONverter is rated by its output Amps @ 12v.

Plugging a converter into an inverter outlet makes no sense at all. The inverter would be pulling power form the batteries to make the power the converter uses to re-charge them.

I can't find any inverter or converter with a brand name of "Maximum", so hard to guess what you have. Does this "Maximum' unit have wires to a battery bank?

Wait! Could this be what you have? The Maximum 60A Power Point tracker? That's not an inverter.

IF it is rated in amps. it is most likely a converter, Converting 120vac to 12vdc.

Inverters are rated in watts. IE: 300 watts or 2,000 watts.

Sorry everyone for posting bad info from poor memory. I just returned home and have the correct info. I have a Magnum Energy 600 Watt inverter and a 60 Amp 120V power converter. The inverter has + & - leads that run in the direction to the batteries. The Romex wire seems to run to just one outlet that the converter is pluged into. Question: Is it possible that the sole purpose of this inverter is to operate the converter to keep the house batteries charged, or should I have outlets inside somewhere that will provide 120 Volts from the batteries?

There's no way the converter should be plugged into the output of the inverter. That's totally wrong. The inverter AC output SHOULD run to one or two outlets, usually one at the TV and one near the driver's seat.

Either someone made a total hash of the electrical system in that RV, or you're mistaken when you traced the wires.

OK - That makes much more sense...This isn't such a bad hash job...but I'm guessing it's just a weak DIY.

For your question...That set-up SHOULD NOT be only to charge the battery - That's using the battery to charge the battery
The inverter "should" power the AC system in your coach...and 600 watts isn't very much...only enough for a TV and some small cell phone or computer chargers.

So, here's the basics: I am assuming that your Shore Power cord directly connects to the AC panel/system, that the inverter is hard-wired to that outlet where the converter is plugged-in and there is also another Romex feed to that AC outlet - yes?

- When you are on shore power, the converter should charge the battery (and power the DC system).
- While not connected to shore power, the Inverter will "BACK-FEED" the AC system of the coach through that outlet.

Now, here's the tricks to this set-up...
You HAVE to be sure that you don't run the converter while using the inverter or it will make that "loop" (mentioned above) that will discharge the batteries.

And, if you are running the inverter...then you plug-in to shore power (or start a gennie) you may pop your GFI...but that's not a big issue. So, try to remember to turn-off the inverter before plugging-in to shore power.

And you can isolate that whole set-up while on shore power or gennie, by turning off the breaker to that one outlet.

If there is no other Romex feed to that one outlet...then, I have NO IDEA what they were thinking

Best of luck

An inverter that small will be solely for the entertainment system, tv and maybe dvd player and satellite receiver, if you have those. I would expect only those outlets (one or two) would be powered by the inverter.

It is definitely NOT providing power to the converter - that would be a toal waste of effort, since thebattery cannot charge itself! If you dug further into it you would find that the output of the inverter is feeding some other circuit.
