Default Re: Total Electrical Upgrade

Greetings, Thanks for posting all the info on your upgrade.
It looks like I am in the market for a new converter and interested in how your humming issue works out.
I have the original progressive dynamics in my 87 roadtrek but when you plug it in to shore power it completely drops the 12V system out and does not charge the battery.
The amount of hours it would take me to see if I can fix it would be more than I can afford.
I think just getting the upgraded unit that you bought would be the right idea if you get the humming issue fixed.
Is there anything you would do different or is it too early to tell that yet.
Does your inverter feed the 115 plugs when you are disconnected from shore power, if it does I am not sure how you wired it in.
All the best.

Progressive Dynamics is sending me a new electronics board to replace the board in the converter part of the Power Center. It is easy to replace, disconnect some wires, remove one screw and slide out the old board. I'll report back as soon as it is installed. I hear the noise when the is no load or when the is only a very light load like less than one amp. I run LED lights so it is hard to even put a one amp load on. A normal RV type bulb draws more than one amp which would stop the noise. Other than that I like the converter and would buy from Best Converter and get Progressive Dynamics products again. Those are two nice companies to deal with.

Have you checked to make sure the AC breakers are on and working? Also, there could be some main DC fuses to check.

Are you sure you have a Progressive Dynamics converter? Sometimes older Roadtreks have Magnatek or Centurion.

The PD4045 I bought: http://www.progressivedyn.com/all_in_one_pd4000.html has both AC and DC panels in addition to the converter charger. You might not need all that. You might just need to upgrade the converter part. You can probably keep the DC fuse board and AC panel. Look at http://www.bestconverter.com/ for all the replacement boards and converter upgrades.

Roger replaced just the converter in his Roadtrek: http://myroadtrek.homestead.com/NewConverter.html

Yes, my inverter can power one AC circuit in my van. That circuit gives me an outlet in the kitchen one the the rear bed area and my fridge can run on it also. I have other outlets not on the the inverter circuit. It was easy to do with the Xantrex PROwatt SW Auto Transfer Switch http://www.xantrex.com/power-products/d ... relay.aspx
Owner manual: http://www.xantrex.com/documents/Access ... tch%29.pdf

There are two AC lines and a corded plug on the Auto Transfer Switch. One AC is source, the other is load. The plug simply plugs into your inverter. You can unplug it it you are not using it or leave it in for automatic operation. It senses when you have grid power and automatically switches to inverter power when there is no grid power (if inverter is turned on).

I wired the source line of the Auto Transfer Switch into a breaker in the new electrical panel. The the circuit I wanted to power was connected to the load line of the Auto Transfer Switch.

Thanks for all the information, that will keep my busy.
I checked the the fuses and breakers and it is a progressive dynamics.
When this one was working it used to have loud Hum to it. My hearing is not very good at all and I could hear the hum in our old unit, I could not have it on when I was sleeping.

I contacted progressive dynamics to ask if I can hack the existing unit and put in the new replacement board in the old style unit. I doubt they will recommend it because it might be too challenging for most. We shall see what they say.

I will however give best converter an Email and explain what I want to do and see what they also say. I take it that the cost was good even after shipping or you would not have ordered it.

Thanks again for all the information, I look forward to see how things turn out for you. When I get things done I will do a post up on it as well.

Best Converter will ship via US Post to Canada so you save on all the fee add-ons that FedEx and UPS have. They add up quickly.
Best Converter 1-888-828-1893 is ready to answer the phone when you call. If Randy is not in the office he'll return the call quickly. Let him know the model number of what you have and he'll suggest a replacement.

Thanks Markopolo.

I just E mailed him with my requirements and my model # it is a PD720Q.

I think I may have left this to the last minute as we generally get out before the snow is completely off the ground and the last trip of the year we either have snow or snows while we are out.

Our first trip may have to hold off until the May long weekend but that is cutting it pretty close considering all the other things that also need doing.

Thanks again.

That Second link Might be very handy. When I get home as long as there is no pending project as soon as I walk in the door I think I will be pulling it out tonight to have a closer look.
Thanks.

So many things to do and so little time...
instead messing up this thread too bad, I will keep it short. I will be duplicating what you did in your system. I did have a few minutes to check my PD720Q and there are issues.
The information that I would like to pass along is there is a fella named Wes Miller who is at mastertech that knows the progressive dynamics units very well. He gave me some information that might lead me to fixing/ modding or replacing my unit.
If I can sneak away from family responsibilities for a few minutes this weekend I will be doing some testing.
I might start a new thread if anyone is interested.

I'm interested. You just never know when this stuff will help someone out there.
I can split your posts from this topic to make a new topic no problem.

The replacement converter/charger arrived yesterday and I installed it today. It was easy to do:
Unplug from AC grid power.
Disconnect DC power to the converter/charger.
Remove one screw and take the cover off.
Disconnect two DC wires and three AC wires.
Remove one screw and slide out the old unit.
Slide in the new unit and replace the screw.
Reconnect two DC wires and three AC wires.
Put the cover back on and replace screw.
Reconnect DC power to the converter/charger.
Plug back into AC grid power.

This one seems to make less noise. It is hard to tell because it is very windy out there this evening. I can't hear this one when I'm in back where the bed is.
Also, it is doing its 24 hrs or so at 13.6v first use phase. I want to hear it at 13.2v float which should happen sometime tomorrow.
My converter is installed exactly at ear height. I might pass by within six inches of the unit. If it was on the floor I don't think I would notice the noise on the new one.
