Was going to have a Progressive EMS-WH30C installed before I plug it in anywhere, even my shop. Will that tell me what you are talking about?

Yes, it will tell you if you have 240 volts in your 120 V plug. It should prevent the system from connecting. An easier way is just check the voltage. The highest reading you get on any two legs must be in the 120VAC range. If it's near 200 or above, it's a welder plug. Get a 4-wire dryer outlet installed. You will then get 240V from line to line and 120V from each line to common or ground.

If that's what you end up with, use a ordinary RV adapter (dog bone) to plug your 30 amp plug into.

If a 100 watt solar panel put out 6 amp per hour in 6 hours of sun you would gain 36 amp with no use. How long would have to drive (on average) to get 36 amp back into your battery
In simplistic terms, my engine alternator is capable of putting out 160 amps, and my converter function is capable of putting out 100 amps. So replacing 36 amp-hrs would take less than 1/2 hour.

However, both of those can be throttled down based upon the existing battery charge voltage, and the charge rates the converter and alternator are built to deliver. For instance, the converter has three stages of charging ending in a trickle charge. The solar charger should modify it's charge rate as well, to not overcharge the batteries.

Definitely take the time to read Twinboats attachment. I would not risk anything without using a voltmeter. Way too many people have smoked their RV's.

If the outlet was for a welder you probably have a 220 outlet.

If your RV has 50 amp, have an electrician convert it and you can run all your AC's etc as needed.
