Inverter - 2015 22FB Sport

I'm confused. Has anyone had an Inverter installed on their Sport? I'm still confused on it's purpose and if we need one. Any input is most appreciated.

An inverter changes 12 volts DC to 120 volts AC. If you are boon docking, and need 120 volts AC to run things that you feel essential to your camping experience, you may want an inverter. Otherwise they are unnecessary.

You cannot run high power things which are on for long times such as an air conditioner. There simply is not enough power in the battery (s) to do that. Even though you can run a microwave ovens on an inverter, for very short time periods, the microwave must be a very small one and not used much.

Your sport only has one battery I believe, and it would make the use of an inverter even more iffy.

12 volt power can be used to charge cell phones and other small items. An inverter would be handy to power a laptop, however. Televisions mostly run on 120 volts AC (some on 12 volts DC though) and would need an inverter to operate when camping away from 120 volt power.

Which brings up the point again, if you are camping with 120 volt power available an inverter is totally unnecessary.

I boondock camped for many years without an inverter and did just fine. I have an inverter now and it is handy but not necessary even now.

Hope that helps.

Thank you idroba. Your explanation of the Inverter, it's application and your experience of its use will save me $ that I would have likely otherwise spent that are not necessary.

Do you power all of your outlets thru your inverter or just a select few? We would like to run a small fan while sleeping when Boondocking.

Thanks for letting us know about IDROBA. Nice obit written in the forum. I'm sure I will find more of his posts as I continue to research this topic.

He will be missed ... what a kind person and his postings are a reflection of that.

On the 2016 Bambi that we have there is not an inverter so I exchanged the one the tv is plugged into for the exact same thing except it has a cigarette lighter hole. It has the tv amplifier also. It is a Winegard, bought at Amazon for $20. Model RV-7042. I use a 100 watt inverter that plugs into it for the tv. The TV in the Bambi uses less than 30 watts so it is a great fit. Bigger than 100 to 150watt inverters generally have a built in fan to cool itself. That is noisy and uses power as well. Hope this helps.

That makes sense to me, except I don't follow how you got 12V DC to hookup to the back side of the Winegard. I thought only 120V AC would be going into the box you replaced. Where did the 12V DC come from?

My original Television died during the previous ownership and I negotiated the price based upon my replacing it. I bought a cheap $99 flat-screen from WalMart which was an exact replacement mounting. It uses a small charger-plug which (reading it's label) converts 110VAC to 12VDC to run the TV.
While dry-camping recently, I used an ordinary male 12V plug inserted in the Winegard amplifier on the AS. (So, the Winegard is obviously 12V also, as it has the small cable-jumper, the green LED indicator lamp, and 12v female socket all on the same faceplate above the refer/adjacent the TV.) So, while dry-camping the TV can be run straight from the Winegard Amplifier 12V socket. (Along with a Bluetooth boosted-speaker which improves the small TV audio, and also the Blu-Ray/DVD player, all 3 being commonly hooked to the TV from which they all receive 12V power.)
We watched the hideous 3d debate and follow-ups for two hours while running the refer and furnace on the simple, flooded-cell automotive Group 24 Walmart battery on our 22' Sport. No problem.

WM and others sell 60-100 watt cigar-lighter-plug inverters for less than $20 if your TV doesn't run on 12V.

Additionally... if you want a fan... stop at any 18-wheeler truck stop and pick up a 12V table-top fan for a few bucks.

Altho' I already own a 1200 watt inverter for installation (won it for a door-prize)... I've put off installing it because I cannot figure out what I'd use it for. It won't run AC or MW or hair-dryer because it's too small... and those are the only things we'd miss while dry camping/boondocking.

BTW, just for those wondering:
An INVERTER is named so because if you look at 12VDC on an oscilloscope you'll see a single waveform ABOVE the horizontal line. So and Inverter ...INVERTS that positive waveform to a negative waveform which is also seen BELOW the line... such that it now resembles the Above/Below (alternating above/below) waveform of alternating current.
A CONVERTER (such as your Airstream already has) takes the positive/negative waveform and ...CONVERTS it to a positive/above-the-line wave only thereby mimicking Direct-Current only. (It does this after first transforming it from 110V to 12V.) Hence, the naming conventions of "inverter" and "converter".
And now, back to our regular programming....

Hey Jhess, the 12vdc is there on the backside of the box like you say to run the amplifier to the antenna. The Wineguard that I suggested just uses that 12 Vdc to also supply power to the cig lighter socket that comes on the new box. It still will have the 120v ac for the plug in for shore power. The unit is all prewired and looks identical to the one you are replacing except for the new cig socket. Just remove the wires from the old unit and place them in the new exactly the same place. Should not be a problem for you. If so, let me know. Hope this helps, Joe

I added an inverter to my 2016 22FB Sport shortly after i bought it. It all started with adding a 2nd battery followed by the inverter install. I wanted the capacity to use medical equipment while boon docking and to enable the tv and other small appliances. I did this back in March and it has worked very well. Here is a link to my posts under the title "We Made Some Changes".

Posts 127 to 131 pretty much cover the story including photos of my "mods".

Hope this helps you.
