Stupid question I guess...

You asked if it charges ALL the batteries. It depends on the Motorhome. Some charge BOTH banks(chassis and Coach) and some do not, EVEN the same brand and model may vary. The Inverter/Charger is connected directly to the Coach batteries and will ALWAYS charge them when 120 voltage is present(Genset or Shore Power). As to the Chassis batteries it depends on if the optional charge module system is installed. The Inverter/Charger has NO chassis charge module or circuit to do that. Your best bet is to take a DC voltage reading at the chassis batteries, apply 120 power to the RV, wait 5 minutes and see if the DC voltage at the chassis batteries goes over 13.1 volts, if it does the RV system charges both battery banks.

"stepdad".....I wired just a 20 amp service to my side yard 10 years ago. It's bene plenty for both my DP's, even enough to run one A/C. Unless you plan to live in it, you really don't need that much power/expense for storage.

WHOA! Rv power source is NOT the same wiring as a household range! Good advice to look up the correct wiring diagram. 240 volts could fry your electronics. 50 amp RV service is two separate 120v legs. No problem to use adapters and step down to a 15 or 20 amp household plug to charge batteries.

Let's see...
L1, L2, Neutral, and ground...
L1 to L2, 220VAC
L1 or L2 to Neutral, 110VAC
Ground is ground.

Note the second sentence: "It is a misconception that this 50-amp RV service is something special. This service is a STANDARD 120/240 50-amp 3 pole with 4 prongs used for numerous applications."

30 AMP service, however, is NOT a three prong 220VAC service! It has L1, Neutral, and ground. It is 110VAC ONLY, and should never be connected to 220VAC!

I just finished up the electrical in my neighbors kitchen remodel. They had me wire for a 240v/40A double oven. I guess either their oven or my RV 50A outlet in my shop must be wired incorrectly. Miller, please tell me what I did wrong since they both work.

NEC Article 551.46(C)(1) FPN is the correct configuration.
A 50 amp is the same 120/240 as used in ranges.
30 amp configuration is a NEMA 30-TT and used for RVs only.

congrats on the new rig.

Hey good folks,
We just got our first diesel pusher and I have a stupid question. When the DP is parked in my driveway and not hooked up to shore power does the generator when going charge up all the batteries?

~Thanks, John

To directly answer your question yes your generator will charge your coach batteries. However running your generator is unnecessary. There is a Walmart in Ephrata. Go get a 50A to 30A or 50A to 15A adapter. If you get a 50A to 30A you will also need a 30A to 15A adapter. Next pick up the heaviest gauge extension cord you can get Some Walmarts carry the 30A RV extension cords and if you can get one of them great they are generally heavy duty and will have a lower voltage drop! This is exactly what I use at home. Next use the 50A to 30A adapter and then the 30A to 15A adapter to plug your coach into a standard wall outlet. This will provide plenty of power to charge your batteries. This will avoid the need to run the generator unnecessarily while you wait. Another thing to note is you will need the adapters I mention above if you do much camping. I have used 15A, 20A, 30A RV, 30A 240V generator NEMA L14-30, & 50A RV to power my RV. As long as you have the correct adapters any of these power sources can work. You would do well to have adapters for the three most common outlet types 15A household (NEMA 5-15 R), 30A RV (NEMA TT-30), & 50A RV (NEMA 14-50) in your RV at all times. It is also a good idea to have at least one extension cord. I actually regretted not having a long enough extension cord on one of our trips. Have fun!

I leave my 50 amp southwind plugged in to a 30 amp plug all the time at my home,it keeps the batt charged up all the time.Check the battery water level every month,run the gen with a load every month also.
