My SIDE solar mount was wired with 12awg directly to the battery. I use it to power my macerator pump.

Thanks again for all that info. It's a lot to chew on.

That has to be a first. What year is your unit? I've never seen 8ga used before. Ive probably got 50+ Rv and boat system installs to date and have never seen larger then 10ga. And 12ga for those side connects is normal.

I see your not to far from me. I'm in Fredericksburg so if you need any advice let me know. Not looking to sell you anything, just tired of seeing crappy solar installs that just flat out don't work.

And FYI, don't take any advice from that "big Ashland area" dealer on what you need. They are going to sell you things you don't need, then try to sell you more when it don't work.

Mine is a 2016 377RLBH. Ordered in October of '15, delivered about 7 weeks later, in late November. If if went by the charts, I could have gotten away with 10awg if that's what was there, but I'm glad that it was 8awg.

Only because your at a higher voltage. Most aren't. 200 watts of 12v panels would overload 10ga (11+ amps in full sun)

I don't run panels on RV's in series for reasons that are too involved to explain here.

2016 model year.

It only took the manufactures 10 years to here what what what we've been screaming at them for.

Yea, I have 300w, but at 34.4v, at max output it's only 8.7A.... The 8awg works well for me. These panels are 2007 vintage, as this is the second RV I've had them mounted on. With some of the new technology panels that have been released since, there are probably better set-ups than mine.

What brand is recommended. Can any panel be used?
I chose Zamp 160 Watt portable since trailer is only pre-wired on side/frame area. If it were pre-wired on roof I would have opted for fixed panels instead. Can't afford the cost of that installation right now so portable for now, works pretty well for my application. Plan for future to to convert my portables into hybrid combo with fixed panels on roof.

Good luck

Thanks. I'm not doing anything right this minute. I'm still in information gathering mode. I'd like to get the 21QB and I had noticed the "Solar Ready" note in the brochure.

In January 2017, I'll get serious again about selling my current trailer, Koala 21CS. Too busy right now. We'll be on the road going to 11 of 12 Va Tech football games this fall.

As for that rather large Ashland area dealer, I share your sentiments. If I need service on my trailer, I go to a nearby RV service business. They don't sell RV's, they just service them.

If/When I get the 21QB, I'll try to reach out to you concerning Solar.
