2006 Limited Inverter Replacement

I have a problem with the charging portion of my inverter. When the coach is NOT plugged in to shore power my house and chassis batteries show 12.8-13.0 volts. When I plug in to shore power my house batteries immediately drop to 5 volts and will slowly continue to drop. If I go into the coach and disable the charger via the control panel the house batteries go back to 12.8-13.0 volts. This is the original Xantrex RS2000 inverter.

I have owned the coach for 5 months and before this problem the charger has always seemed to have to high of a voltage during charging. With the temp sensor connected I would see 14.8 volts in float mode. Disconnecting the temp sensor would bring the floor voltage down to 14.2 volts.

I want to replace this inverter. It is 9-10 years old and after reading many other posts regarding the RS2000 I am even more inclined for a replacement. I don't want my inverter/charger to continue to be a problem. I am considering a Magnum MS 2012 or MS2812. My questions are:

1. I have to decide if I am going to do the work. By buying the components online and doing the work myself I can save a lot of money . I am very confident in my ability to physically install the system and make the connections. My concern is if it will be plug and play. If I have Silverleaf or Vansco network issues I will need professional help. I have not read about any Vansco issues when replacing an inverter and the Silverleaf issues I have read about seem to be with the Apex models. My Silverleaf system only monitors things going on, there is no user input.

2. I need to choose between the MS2012 and the MS2812 inverter. I do not have residential fridge. I do not think I need 2800 watts of inverter power however I do have 8 6volt house batteries and was wondering if I should have the higher capacity charger, 75a vs 50a.

I would appreciate comments from anyone and especially owners of a 2006 limited model.

The MS2012 charges at 100 amps, not 50.

Both use the same case, so size is not an issue. Slightly larger than the Xantrex.. Mine was plug and play, but I don't have the Silverleaf or AGS. No issues with the Vansco. Used same remote cable, so no wiring issue.

Thanks for your reply Jim. After calling Magnum I found I was in error. The 2012 has 100a charger and the 2812 has 125a charger. It was good to hear you had no Vansco issues. I am thinking I am going to take this on myself.

When I changed from Xantrex to Magnum I had to change the remote connector from an 8 wire to a 4 wire connection. It's easy to do if you have the tools and understand the wires needed. The remote manual will explain how connect the wires.

From what I have been told, Xantrex sometime switched from a RJ11 cable (6 wires) to a RJ45 cable (8 wires) for the remote. My '04 had the RJ11 cable. Not sure about an '06. But the Magnum needs an RJ11 cable. Fortunately it is easy to change a RJ45 to an RJ11 cable. Impossible to change an RJ11 to an RJ45. (Not enough wires.) But you don't need to do that for the Magnum. But you might need to if you buy a new Xantrex instead of the Magnum, as the Xantrex will likely need the RJ45 cable.

They look similar. A phone cord is RJ11. Ethernet is RJ45, a bigger plug.

I have not confirmed it yet but if it is the same cable as my temperature sensor it's RJ11.

Rick,


Our new Xantrex RS 2012 uses a Cat 5 (Ethernet) cable to connect with the Silverleaf. Maybe give Corey a call at Silverleaf Electronics and see what he says?

Hey Todd, I did call Silverleaf and talked to Mark before I was thinking about taking this on myself.

2006 Limited Inverter Replacement

Unless you have something else undisclosed that you need the added wattage for, the 2000 should be plenty, 100 amp charging is fine for eight 6v batteries, no reason to pay for wattage you can not use.
