For what it's worth, the current versions put the converter under the front seat, as suggested, taking up storage space. Raz

Older converters, which usually only consisted of a step down transformer, a couple of large diodes and a few filter caps, could easily take the heat from a nearby furnace. Modern electronics are not always so forgiving, with even modest heat being the #1 enemy of semiconductors.

At over $200 + a lot of work, I still wouldn't put a PD-4645 under the furnace, regardless of where Trillium had been installing earlier, (and since moved ?) components.

What work? Take out the old converter, don't cut any new holes, don't cover the old hole, don't run any new wire. Putting the new converter back in the same place as the old one has to have some advantages over a new location.

I suspect Trillium moved the converter because they could no longer get one so small. The one they put in the kitchen was much larger then the one they put under the furnace.

As for the cost delta, the difference is $20 at Best Conveter:
PD4045 45 Amp Inteli-Power Mighty Mini Power Center
4600 series Upgrade Kits

Neither includes AC breakers.

Work?
When using the PD-4645 as a stand alone converter I think that you will also have to cobb up some sort of DC fuse panel and an A/C breaker panel and find a space for that somewhere as well.

Cost:
As I mentioned a few weeks back, the PD 4045 is available from www.teardroptrailerparts.com for about $155, even less than the Best Converter price.

Features and Benefits:
The PD-4045 comes with a 12 position 12VDC fuse panel built in with leads attached, as well as space for up to 6 a/c circuits, all safely and neatly enclosed behind an easy access front panel.

And, when it's time to sell, you have an added value feature of a modern power center that a pieced together power center can't provide to interested buyers.

I'm Done.....

Bob, I think you meant Teardrop Trailer Parts. I went to that site and did not see any converters, so price comparison is a bit difficult. I suspect their price delta would be comparable to Best converter. If I ever upgrade my converter, I will ask them for a quote on the PD-4645. Assuming I don't find one on kijiji first.

The PD-4645 comes with a 12 terminal DC fuse board as shown in this post:
Trillium 4500 replacement converter?
It is necessary to find a place near the converter to mount it, hence the bubble gum and bailing twine comment of mine previously. What I would actually do is fibreglass a piece of 3/4" plywood to the wheel well. Then I would mount a small NEMA 4 box to it. This box is likely where I would mount a few panel mount 120 VAC breakers with a physical separation between the 12 and 120 V sections. I would probably connect the whole assembly using liquid tight flex conduit. Kinda overkill, but that is how I role. I don't foresee any resale problems, because all of my Trillium 4500's are going to my kids, except the front dinette model I will keep for my wife and I. I am still looking for that trailer.

I understand your dedication to the PD-4045. In the end I think the PD-4045 may be the best solution for an RV that has the room. It would be nice to have the AC breakers and the DC fuses all in the same place. For a Trillium 4500 that has a converter that is already under the furnace, the PD-4645, or any of it's variants, is a better fit.

My Bad.... contact Frank Bear at www.teardroptrailerparts.com 269-665-9060 and tell him what you want. He quoted one to me about 3 weeks ago and, as mentioned, I have bought at least 6 of them from him in the past. They don't list everything they have on the website.

The fuse board included with the PD-4645 is designed as a replacement for the stock 4 or 5 fuse panel in the original converter chassis.

PD also makes a very nice external fuse panel with about 15 fuse positions. I put one of those,and a 9200 converter in a FGRV

Here is a link to the PD power distribution panels for those that, due to space limitations, may have to have a seperate converter and power dist panel:

Bob,
I had not seen those stand alone distribution panels. In my case the Scamp side dinette has very little space to work with. The PD 5000 distribution panel is actually wider than the 4045 by over an inch, and lower by 1 3/4". That may help it fit the side of the bench, but space would still be needed inside for the converter.
I was thinking that the trailer tongue would be a better spot. A suitable WP enclosure would need to be mounted between the propane bottles and the front wall of the trailer. Some ventilation would need to be provided such as louvers.
The performance of the charger would be enhanced due to it being mounted next to the batteries. That charger only provides 13.4v after bulk which some would say is over a volt too low. Subtract the voltage drop of 10' of the 10 ga. wire Scamp put in the trailer and you get poor charging. The drawback is that the DC circuits would have to be extended from the old location to up front, and the AC also fed to the input and all AC circuits extended. Voltage drop there would not be so critical. The exterior enclosure box would be expensive too. I may just do mine that way. No fan noise under the bunk either.

I ran 4 gauge to mine. It puts out up to 45 amps, 10 gauge isn't sufficient anyway. The fan isn't silent, but its very quiet.

We installed a PD-4045 in our 13' Scamp in the same place as the original converter, under the rear dinette seat, without problems, certainly nothing like "Poor Charging" would suggest. I think that the whole distance/voltage drop issue is being overrated. But then, I get blamed for saying things like "Don't worry, Be Happy".

As far as putting the entire power chassis/dist panel in the tongue, first consider getting out in the rain/snow/dark to fix a blown fuse/blown ac breaker.

I posted the link to the Dist Panels primarily for the smaller DC Dist Panel. Basically, if someone has room for the larger ac/dc panel they should have room for the PD-4045. I think that the larger panel is more intended for those using stand alone converters.

Considering the lack of real world complaints, I think that the entire issue of charging rates and voltage drops, esp when using the PD series products, is waaaaay over discussed.

Bob,
Putting it in the stock location is certainly the easiest. It would take rehanging the storage compartment door, and would be crowded, but possible. Due to the PD's conservative charging voltages I wouldn't skimp on the output wiring. To each his own. I'm trying to fix a system that doesn't work to my satisfaction. The original panel still works probably as good as it ever did, but it is so slow to get the charging done, and doesn't have multi stage ability like the PD.

That is a good point. My home panel is outside and I have had to go out a couple of times to reset a breaker in the last 15 years.

Yes, that is what I thought. Buying the stand alone and combining with the distribution panel may fit better than the whole load center. The height measurement is more favorable, so it may install just above the hinges for the storage door. Installing the load center would require removing the hinges and spreading the spacing of them to allow the face plate to fit between them. Thanks for the link.

You may be right, but it makes for some colorful posts. There is probably something to be learned from it.

Jared,
4 gauge only loses .22v per 10 length with the charger at full tilt, so you're probably topping up pretty good. With 10 gauge the drop would be 1v. The ground return would also add some resistance depending on whether you used the trailer frame for the return or another length of 4ga.
The fan in my stock American converter is really pretty quiet too. It never bothers us.

I ran a 4 gauge ground also. I don't really believe in using the frame.

So if i go with a PD 4045 i could pull out the old one rewire to the new PD 4045 install breakers in it and if i add 12v components just wire them and put a fuse in the panel for the 12v component as i add them ?
