Hey, just started reading this thread, great info so far, but (and I repeat "just started" and I haven't gotten through the whole thread) but would it be cheaper to have the factory pre-install?

Terry.

Hi Terry,

My personal opinnion would be to have the factory prewire it on an Airstream just because they can be more challenging to wire up yourself. However, pricing ranges depending on the quality you choose. If you have any other questions please let me know.

Regards,

if the question in post 141 is about PREwire...

they all come with this as a standard part of the wiring.

it's doesn't require the buyer to "ask" for solar prewire.

IF the question is about the value or "cheaperness" of having factory INSTALLED solar during assembly...

versus adding a system AFTERWARD...

that question IS covered earlier in this thread and in several others like this...

AAAhhhhhhhh! Another solar thread!!!!

Speaking of wire, I'm afraid that Airstream is still 'behind the curve' when it comes to installing the proper wire gauge for their solar installations. 12AWG and even 10AWG just doesn't cut the mustard any longer. They are, after all, still about profit from their product and IMHO (and I may get flamed for this.....

) still cut too many corners in the persuit of that profit!

We (AM Solar) have begun using (about a year ago) 8AWG to connect the solar panels to the combiner box on the roof and then 6AWG and depending on the total array wattage, as large as 4AWG to connect the array to the charge controller.

Again, in a solar charging installation, one of the main considerations is to squeeze every possibly watt from your panels and charge controller, hence the use of bigger wiring. This is also the reason that we recommend the use of AGM batteries and specifically Lifeline AGMs as your battery bank. They have the lowest internal resistance of any commercially available deep cycle battery currently on the market which allows them to re-charge quicker than the others as well. They also exhibit the best construction and heaviest plates within their battery structure. This lower internal resistance also allows the Lifelines to put the elevated charging amperages obtained from the 'boost' feature or our charge controllers to better use in quicker charging of the battery bank.

I'll be conducting a comprehensive seminar on solar charging, basic RV electrical systems and batteries at the Vintage Restoration Rally in Albuquerque starting on 6/9 and hope to be doing an actual solar charging system installation as well. Something anyone seriously considering adding a solar charging system to their trailer or MoHo should try to attend.

And just a quick reminder......YOU GET WHAT YOU PAY FOR!!!

Thanks for the warning.

I notice that no one has contributed to this thread for a while but thought I would see if I could get some help. I have a 2008 16' Bambi DWR with the factory installed solar panel. This last trip the battery went dead and the display light started blinking. I have replaced the battery and the display is still blinking. What should I be checking first? Before the battery went dead I remember seeing the percentage condition of the battery but never any reading for solar at all.

I forgot to mention that I am pretty hopeless when it comes to electrical stuff. I am hoping that someone will suggest some step-by-steps to follow to find a solution. Thanks.

I’m still not sure where I would easily make a connection if I ever wanted to add a portable or flexible solar panel.

Hello,
Most portable systems come with a charge controller and you attach the pos.neg. wires to the correct batt.posts with clips.Works great as long as you are relieved of your panels by interested parties

Lew: Quick couple of questions: Previously, I've rigged my '77 31-footer with a PV system including a Morning Star charge controller, Inteli-Charge 9200, Go-Power 2500w inverter and an Auto Transfer Switch. Reading some of the specs on the Magnum inverter, it sounds like its got a built-in ATS and battery converter/charger. Is this the case? I'm planning/designing a PV system for my '85 25-footer and would like to fore go extra components if possible. The ATS I used on the '77 had a built in AC power surge protector - does the Magnum inverter have a similar feature built in?

Thanks,

Art

Hi Art,

Magnum inverters, specifically the 2000 watt varieties, have an integral 100 amp charging section with both voltage sense and temperature compensation. The units are pre-programmed for several different types of batteries, and adjust the charge parameters accordingly.

And yes, there is also an internal transfer switch that energizes your inverter circuits when on shore power and then also energizes these same circuits from battery power when the inverter section is activated.

You will need the ME-RC remote control panel to operate the inverter and to provide the proper programming on installation. IMHO, it's better to use a stand-alone surge protector on a system. If you do experience a power surge and the unit is sacrificed, the only component you need to replace is that surge protector. If it is built-in to another component, a dual function component would have to be replaced at a much higher cost.

Look at the 'Surge Guard' brand for a quality plug-in surge protector.

Lew:

Many thanks for the advice. It would appear that the Magnum 2kw varieties with the remote will do the work of the Univolt or InteliCharger, correct?

I'm planning on running two group 31 Life-Lines for 12vdc storage.

I'll research the Surge Guard to use as a potential "sacrificial component."

Well,

I have posted on my thread about my camper my updates to my camper...

http://www.airforums.com/forums/f396...tml#post810903

and I decided to update this thread as well.

I currently have the Factory Installed GO Power 110W system, and I will be purchasing a 125W, and (2) 80W panels to max the system out at the rated watts for the Regulator. Its is rated to regulate 25amps, and I should be right at 22.9 if I am ever lucky enough to get that much direct sunlight on my panel.

The Carmanah Go Power manual says that the 10g factory wires should be fine, and I had my father take some measurements on my roof and the panels should fit perfectly with 110W that already lives up there. Going to be mounting special brackets so I can angle the panels towards the sun and I hope to change the batteries to AGM when I get back from Afghanistan this summer.

Not sure when I will have photos to post, and currently I am going to try and schedule with the Factory to install the other panels, since I live close.

So I will keep people posted. Also, I did just file for my tax credit on my first panel. So I will update people on how that goes....

SHAGWAGONTWO · 03-18-2012, 01:56 AM

I pick up my 1st Airstream next week... looks like it comes with 16' X 4.5 awning-- I noticed in the photo you posted that you have 2 Awnings... Did you but the 2nd Awning NEW or USED? Any advice there or website you'd recommend?

Thanks.... Thomas & Kelly

Note, no inverter, so I can't relate to tell you if the $2300 asking price is good or not. I may very well pick up an inverter to power the television in the future but I do have two Honda 2000's for the airconditioner so I am not fully dependent upon the solar. Really doubt that I could be with my set up without being really frugal.

Hello,
I believe the factory wiring is 10 ga. Many feel that when you upgrade to higher wattage that upgraded wiring is necessary.Using wattage above 110 watts is less efficient with 10 ga.wire.
