Question

Question
When plugged in at home on a shore 120V outlet. The converter "adjusts" and you get get 120V power to the outlets. Without the converter there is no power. For those that separated the systems (no converter) did you wire so it works with the 240V double pole trailer cord with a 120V connection? Is that is even possible? Or just live with it only operating with a 240 V shore connection and accept that is a drawback for separating the systems?

Hopefully no one is running 240 VAC to any trailers in this group. That big three prong plug on the shore power cord isn't a 240 VAC plug, like a range plug, it's indexed to plug into only120 VAC, 30 amp outlets.

The converter is the part of the power chassis that "Converts" 120 VAC to 12 VDC for 12 volt things such as lights, water pump, fans and furnaces.

There is usually an AC distribution section that has breakers for incoming AC and internal AC loads such as the converters input, AC outlets and the air conditioner.

Without the shore power cord connected there usually isn't power to any of the AC outlets unless an inverter (12 VDC to 120VAC) has been installed.

That said, European caravans do have 200-240 volt shore power connections, but that's their standard.

As far as I know the only 240 Volt system is in some very large RVs. Those that require a 50 Amp service. The 12 volt system and 120 Volt system in all cases are separate. The converter doesn't "adjust" anything. It simply powers the 12 Volt system and charges the battery. Simple as that.

The 30 Amp power cord has three wires, Hot wire, Neutral wire, and Safety Ground wire. Thus three prongs at the plug.

There are some power boxes at campgrounds that provide 240 volt 4 prong connections (50 amp). An adapter to out little trailer 30 amp connectors can be used. It simply does not connect to the other hot wire. 50 Amp service with 4 prongs is hot, hot, neutral and safety ground.

Let me guess.... The first one was an "American" brand, the second one a WFCO.

If you want to go back to a real power center, one with a 3 stage charger etc., try the Progressive Dynamics PD-4045

Well dang, I was all set to spend money on a new converter just to upgrade to a newer one and a smart charger, but now I question why (at least right now). I have a good separate "smart" battery charger, and everything works fine in the trailer as is. If I am worried about over charging the batteries I can either just disconnect them when on shore power for extended periods (to prevent boil over) or somehow disable the existing charge function. I will investigate.

Unless your battery charger is specifically designed for deep cell batteries your concerns are very valid and may well happen....

I have my PD-4045 plugged in 24/7 for months and months at a time and have yet to have to add more than a drop or two of water every 6 months. And, when I want to use it, it is always fully charged and ready to go. Right now I am tapping in a second battery and expect the PD-4045 to take care of that one as well.

And, HoooRay... you will be updating to current SCAMP power center specs.

Thanks for the info. I was mistaken that the 30 amp plug was 240V.

So I am wondering what everyone is using out there.
I do travel backcountry road so need something that will work well and last.
I boondock so most power comes from SOLAR Panels manufactured in
solar panels factory but like to plug in sometimes on the road and at home to chill down the fridge and keep the battery up.
So any info would help alot. Do not need a large one 20 AMPS will be fine.
THANKS DAVE
Well just got the information I have been searching for..Looking to install LED and battery system and I got perfect way to do it now.
.
Anybody out there using similar battery system?

Good answer Bob. Never really thought about 240V in a trailer. Had to deal with that when stationed overseas but used converters to drop the V to 110 for home appiancenes. MMMM, never even saw a travel trailer in my time there.

"Anybody out there using similar battery system?"

I am....had the same old converter problem....got rid of the guts in the bottom half of power center....cut the bottom half of case off...rotated panel 90 degrees and reinstalled in a spot that was difficult if not impossible to use for anything beforehand...hard wired a three stage charger, added a 12V panel meter in plain view from anywhere in the trailer.... turned the area that the power center used to occupy into a very convenient shoe drawer........a "win, win, win" situation so far and I've been using it all summer.....always know at a glance where my batteries are at....when the batteries get down to 12.3 or 2 it takes 8 to 12 hours for the charger to bring them back to full charge (12.6V on an open circuit test....or 14.1V with charger running).....if solar is producing well the batteries never go down below 12.4V....my usual "cycle" is 2-3 nights unplugged followed by one night plugged in

with the PC I had, the 12V fuse panel had some circuits fed straight from the batteries and some circuits fed from the converter ("unfiltered power, not suitable for radios, TVs)...a one wire simple connection later (blue wire in last picture) and all circuits are now fed from the batteries....the charger is on it's own breaker (red, old air conditoner circuit no longer needed)....I use that to turn the charger on or off

Neat, professional looking work. Where are you folks getting your battery meters?

I disagree with that thought Bob. Someone might be searching for the same information. I think it best to try to keep as much information together as possible.

You have just demonstrated what I mean. Someone could be searching for info on old dead equipment, or it's suggested replacement and learn what the current recommendation is.

meter ???

I got mine from DX (Deal Extreme...easy to find)

I should ad that I found the stock fan on my charger a little noisy so I removed the stock fan from the charger, cut larger holes for inflow/outflow in the housing and installed a computer fan (dead quiet) on the exterior of the housing....got the fan (and a whole bunch of LEDs) from the same place

pictures show the panel meter (with the small 150W inverter I occasionnaly use to charge/use some devices like phone, laptop...those are my only need for AC when unplugged)......and the shoe drawer that replaced my big old power center

The original question was about what fuse panels were available in 2014 and that topic wasn't even mentioned in the 5+ y.o. previous materiel.

I agree keeping old posts can have some value, but tacking new questions and non-related questions onto them, without a fresh topic sentence, can be counter productive.
