Question Inverter/Chargers

Background. We purchased a nice 2013 AI in July. I have been following the Sprinter threads with interest - good information for newbies like us. The Lifeline batteries are obviously history and I have two new ones coming from a Lifeline distributor. Our coach has a factory 100w solar setup. And it has a Tripp Lite inverter/charger and most of the posts I'm reading refers to Magnum units.

Question. Does anyone know or think they know why Airstream switched from Tripp Lite to Magnum?

Magnums are better, but that's probably not why they switched.

Admittedly Airstream is prone to running changes, but are you certain you have the original 2013 AI solar setup? My 2013 AI has a 50W solar panel and a Magnum controller.

No, I'm not sure. I was told 100w by the original owner, but... The window sticker listed a Tripp Lite Converter/Inverter - 45 Amp Charger/750 Watt invtr and there is an addtitional charge for a solar panel @ $1307.00.
I had assumed the additional charge was for upgrading from a 50 to a 100w panel. And I know I shouldn't assume.

The 50W panel was a option for earlier years, not sure when it or the 100W panels became standard.

Airstream told me that they changed to Magnum because they changed the generator and the new one wasn't compatible w/ the Tripplite.

My 2012 FC 28ft has a 106W system installed at the build. Two panels each 53w each.

So you're thinking my Onan 2.5 KW Quiet MicroLite LP Generator/Remote Starter is different from newer AIs with the Magnum inverters?

If what Jim Parrett told me is accurate, then yes.

Remote start...

It may be the remote start feature itself that makes the difference.
Not all inverter's support an intelligent remote start where the generator will start based upon a command generated by the inverter... either to provide additional AC power or to recharge a low battery (or both).

I don't know why they changed from the Tripplite to the Magnum, but I know why you should, too.

The Tripplite is a "dumb" charger. It will overcharge your AGM Lifelines, for one thing, and ruin them. The Magnum can be left plugged into shore power, and knows when to bulk charge or float charge. The Magnum is a pure sine wave inverter; the Tripplite is a modified sine wave. This may have some bearing on some electronic devices that don't do well with modified sine wave inverters. The Magnum has a much better status report as to the condition of the batteries, and with the remote, a much better way to control it, and know what exactly going on with the house batteries.

I made the switch on my 2011 and am glad I did. Highly recommended.

My 2013 has the Magnum Inverter, but there is no automatic start. Probably another case of what parts Airstream had in stock when they assembled the unit.

I am a little confused. My 2015 does not have an intelligent remote start only a remote start. Is this simply something the Magnum is capable of doing or am I missing something? Thanks

The device you are asking about is called an auto generator start, or AGS.

Airstream has never included an AGS device in any Interstate. They can be added without too much difficulty if you have the Magnum inverter/ charger.

The can be set to actuate your generator for either a low battery voltage situation or a high ambient temperature condition. If the door A/C is set, the ambient temp sensor of the AGS will fire up the genny so you have 120VAC power and the A/C will then operate to cool down the coach.

Magnum lists their AGS as the ME-AGS-N ( for network).

Other very useful upgrades are the remote temperature sensor and the programmable ME-RC remote.
