You're probably right. But hopefully I've at least given you something else to check in your quest for the battery-eater.

Don't ever deal with Dan. If you get Dan, hang up. Talk to Randy McNeely. Dan's lazy response is take it to a dealer. He refused to send me a failed backup monitor and insisted I take it for a ten hour there and back drive to a dealer for replacement. I bought one on eBay for $30 instead. When I protested, he actually said if it was a Ford, you would have to take it to a dealer. Yeah, like there is an Airstream dealer nearby in every town in America.

I have further information which may be of use to anyone with the 2014 updates, i.e. Magnum Inverter and Panel, etc…

I have noted that with the batteries disabled, the Solenoid for propane is also off; the antenna amplifier is off (green light goes off), and the LP detector green light goes off.

What does bother me are the following:

1) The Magnum Remote Control panel still has power.
2) The SunExplorer panel has power (but may be OK)
3) The tank capacity display has power and does indicate the contents of all tanks. *It also displays the chassis battery volts but not the coach batteries.
4) Trying all the switches around the interior, the tank heater switch still functions with coach batteries disabled. This was another surprise.*

I flipped off all the fuses in the box under the rear seat, and that made no difference.

You may not notice this if you park outside since the solar change may be enough to compensate, but I park inside.

I think there's a wiring issue, and I'm wondering if it may be because my 2013 model was at the front of the line with the 2014 upgrades, and they didn't get it all right!

With the Magnum Remote Control panel having power it suggests the Inverter also has power, and that may be at the root of it.

I have been in contact with Dan at Airstream and frankly, not got very far. He has said Airstream will work with the dealer to resolve this.
A Corporate response if ever there was one.

So I finally got my solar panels installed, and I am very happy. I had 2 100w AM Solar panels installed as recommend by Lewster. I had the 1st panel installed where the factory 50w panel was, and the 2nd panel was installed in front of the Maxxfan. As you can see, they were a perfect fit. The factory panel would only provide 2.8A and now I get 11.2A. I street camped (dry) yesterday, watching TV until late, and the batteries were fully charged by 9 the next morning. I may not have to plug in again parked at night in the driveway. Yay!!!

David,

Looks nice! Which panel did you get? Which controller did you get? Who installed the system? What was the total cost?

Thanks,
Wayne S.

Hello Wayne,
The panels are AM Solar GS100 (link provided by Lewster way up above). I had them mounted by my AS dealer in Corona CA (Southwest Coaches) who said that the existing charge controller was adequate (we'll see, I guess). So it was a relatively inexpensive upgrade. The panels and installation kit was $764 and installation was $215. Totally satisfied so far. Hope that helps.

Did they just connect them in parallel and then to original wiring?

Charge Controller Update?

David -- very nice install. You have inspired me to do the same thing and maybe try to squeeze a third panel behind the TV antenna. With that much solar power we may need to update the controller as Lew Faber (Lewster) recommended earlier in this thread:

"• your solar charge controller needs to be replaced with a fully operational 3-stage charging unit capable of sending at least 14.2 VDC (temperature dependent) to your house batteries"

Yes, they just connected the panels in parallel to the original wiring.

I haven't taken any measurements, but a third one might fit behind the TV antenna.

And yes, I'd like to look into getting a better charge controller. I'll have to go back up this thread and look at the controller that Lewster recommended.

Thank you for your kind words. Regarding the charge controller, don't we already have a multi stage charger? I thought the Tripp-Lite has a 3 stage charger built in and the new Magnum inverter has a 4 stage charger?

The solar panels are generally wired— through their own charge controller— directly to the house batteries, so that the batteries can charge even while the unit is in storage with everything else switched off. Going through the inverter/charger would mean that you'd need the use/store switch on "Use" and the inverter/charger on "charge only" in order for the solar panels to charge.

Thanks protagonist.
Do you know what make and model charge controller is in our Interstates? I went through all the papers I got in the AS bag/case, and didn't see anything regarding charge controllers. Also, do you know where they hide the controller itself?
Thanks,
David

Not sure. Some panels have integrated charge controllers, built into the panel itself. Multiple-panel installations most often use a separate controller that all the panels feed into, and that would probably be somewhere behind the face of the control panel enclosure.

Really small panels may not even have a charge controller, instead feeding raw DC current to the batteries, but they don't put out much amperage to begin with. The factory 50w panel may fall in that category, since it only puts out enough for a trickle or float charge anyway.

Hello David, if you have the Interstate with the 2014 upgrade, like mine, your solar charge controller is a Sunexplorer PVCM25D made by Atkinson Electronics, Inc.
Thank.....Peter
