2013 Elevation 3912 - Converter Charger Info

Hey Guys...so this is just an informational thread to maybe save some folks some time.

I'm about to upgrade my single 12v battery to 2 or 4 x 6v batteries and have been spending time researching converter chargers to make sure I don't kill the new batteries with crappy standard gear. That said, there is very little information on the web as to which Converter/Charger comes in any unit.

I called CR and they were unsure about which converter/charger I had.

My goal is two fold:

1.) Be able to boondock as long as possible on Battery Power without running the generator.

2.) Recharge said batteries in as little time as possible without running the generator for hours upon end. Even though the onboard Gen is an ONAN 5500, which is pretty quiet, I'd still prefer to run less Gen and more batteries.

To Goal # 1 - I have decided to purchase the Trojan T105 batteries. Each battery gives 225AH at 20 hours. Four (4) of these guys will give me about 450AH @ 20hrs (so approx 22.5A for 20 hrs, assuming I don't let the batteries charge down past 50%) to play with. The total AH pool will be 900AH.

Knowing that I'm not going to need 22.5A per hour (running TV, Music, Lights, Furnace, etc...), I should be able to run longer. I am aware I'm not taking the Air Conditioning into account.

To Goal # 2 - Make sure I have the appropriate converter/charger system so recharge the 450AH as quickly as possible so I run less GEN power AND maintain my batteries for optimal performance during the storage months (my unit stay plugged in to 120v when at the storage place) without over charging them.

Since the internet wasn't playing ball, I decided to head to the unit and take a few pics. Turns out that in MY SPECIFIC 2013 3912 I have the Progressive Dynamix PD4950 18LV with Charge Wizard. Essentially it's a Stage 4 system, which is good news since I no longer feel I need to upgrade it.

I have seen on the web several 3912s with 75A systems advertised.

Here's the details:

Progressive Dynamics PD4590K18LV AC DC Distribution Panel & Inteli-Power Converter with Charge Wizard 90A Camper Trailer RV




90A AC/DC Distribution Panel and Inteli-Power Converter with Charge Wizard

AC/DC Distribution Panel and Inteli-Power Converter with Charge Wizard

Inteli-Power 4500 Series models can recharge the battery to 90% in 2-3 hours using our patented Charge Wizard technology.

The built-in Charge Wizard automatically selects one of three operating modes: BOOST, NORMAL, STORAGE.


Boost Mode - Indicated by green LED remaining on. The output voltage is 14.4VDC to rapidly recharge the battery up to 90% of full charge.

Normal Mode - When the battery is between 50% and 90% charged, the green LED will flash once per second. When the battery has reached 90% of full charge the green LED will flash 2 - 3 times per second. In this mode the output voltage is 13.6VDC and the converter is safely completing the charge of the battery

Storage Mode - Indicated by green LED flashing every 6 - 8 seconds. In this mode the output voltage has been lowered to 13.2VDC, the RV battery is fully charged and the converter is maintaining the charge.


Inteli-Power AC Features:
  • The AC Distribution Panel is rated for 240 VAC @ 50 AMPS input voltage. Maximum output voltage is 120 VAC @ 50 AMPS.
  • Provisions for up to 12 branch breakers (breakers not included).

  • Vertical or horizontal mounting choices.

  • Center feed dual 50 AMP main breaker (not included).
  • AC Panel features 12 built-in push and lock strain relief wiring connectors for quick installation. Saves over 50% on installation cost.

  • Vertical or horizontal mounting choices.
    Attractive light weight panel design made from impact-resistant high temperature polymers.
  • Covered by one or more of the following patents: 5,687,066 5,600,550 5,982,643 6,184,649 6,424,520 6,430,036, and 7,782,002.
Note: AC Breakers are not included and shown for reference only.





Inteli-Power DC Features:
  • Top two fuse holders recommended for low current devices such as smoke detectors and carbon monoxide detectors


  • 12 or 18 Branch fuse holders with maximum rating of 30 AMPS each.


  • Optional terminal block or wired branch circuit connections.


  • Optional L.E.D. indicators identify which fuse is blown.


  • Converter/Charger section is accessible from the front.


  • Converter/Charger ratings of 60 and 90 AMP, which is the largest rating available in the industry.


  • Easy access reverse battery protection fuses.
  • DC disconnect - allows the attachment of a remote DC disconnect switch.
  • Optional DC Ground Buss can be user-installed in the DC wiring compartment.
Other PD4500 Series Features:
  • Reverse battery protection
  • Electronic current limiting



  • Low line voltage protection

  • Intelligent cooling fan

  • High voltage protection

  • Automatic thermal protection
  • Press open door for easy access to circuit breakers
  • Front access to large wiring compartment






The above link goes to the full catalogue of PD Converters in case yours is different.

Hopefully, this will save some folks several hours and or a trip to their unit if they are trying to figure out what converter/charging system they have.

Thanks.

Matt.

Am I missing something here?
Won't you be in need of an Inverter? When I was going to do all that I was looking at Xantrex. 2000 watt/100 amp charger.

I did install 2, Trojan T-105 6V
I wish I had purchased the T-145 while I was at it.

You are not missing a thing mate. I haven't got that far yet. Lol. The next thing is to figure out what inverter is installed. I know there's one there...I just need to find it.

I am by no means an electrical guy.

Stay tuned for part 2!

Update: The PD4950 is an All In One Inverter/Converter/Charger. The Inverter rating is 1550W

Additionally, the PD4590 will "equalize the batteries" every 21 says as part of it's "Inteli-Power" function. This makes me feel better about leaving the RV plugged in all the time while in storage.

I do intend to purchase a Trimetric 2030 Battery Monitor ---> Trimetric 2030RV Battery System Monitor to keep me honest on making sure I do not exceed the 50% unknowingly.

From what I've read, the Golf Cart batteries seem to "like" a deeper discharge so I may on occasion let them have a deeper discharge.

Again, my thoughts behind this thread was simply to highlight the Electrical System in the Elevation 3912, since CR doesn't have a clear picture.

I don't know that I agree with the deeper discharge part. I know they like a steady charge like coming off a solar panel. Go to Trojan's web site and read on their batteries.

Hey, where did you get this info?
I have the same unit on my 3812 Elevation. I can't find any documentation in my coach or on PD'S website that shows the unit as an INVERTER. Also, I have a residential refer and I can't seem to find a switch or other way to run the fridge without the generator or shore power... (bought it used and of course dealer had no idea during PDI)

There isn't a single mention of the word Inverter anywhere in the PD Installation and Operation manual.

I took it right off progressive dynamics website. You can download the manual too.

I then called Crossroads and asked them just to make sure I was reading the information correctly.

Lastly, I went boondocking for 3 days this past week and used just about everything except the AC successfully for over 10 hours. I then started the generator just to top the batteries back up. It took less than 3 hours to run the batteries back to full charge. I repeated this process/cycle throughout the entire trip.

I haven't had a chance to install an auto genny starter and battery monitor yet.

All of the above makes me feel comfortable that the PD4950 is indeed an inverter too.

Cheers

Matt.

Well that's good news. I've obviously missed it on the website. I've got the original paper users manual and still didn't see a mention of any inverter capability.
I'll recheck the website.
Thanks for he help. So is there a switch anywhere that turns inverter on or is it automatic?

Its automatic mate. You don't need to do anything.

Cool. So does it power all the outlets or only certain ones? How do I know the difference?

I see on the unit now where it says 1550 W on the INPUT side but no mention of any 120v OUTPUT.

please don't take this as a challenge to your info, I'm genuinely trying to understand
