He has a very " minimalist" approach.

I've never been that... " thrifty".

But he makes a few good points, while beating others to death.

Thanks Paulie it has served us well, we use the system just as if we were plugged into a power pole except for running the A/C units of course. The sun is coming up, the coffee is made and the news is on the 42" TV, the solar system is already up to 14 amps and climbing. Hope your system setup works as well as ours does.
Happy Boondocking
Mud

Install

M.Y., mine is a portable system thus far, as I am still gathering all the pieces/parts. I have taken it on a week long boondocking with 2 panels, and have observed a high of 33 amps!-using smaller wire than I plan to use for the permanent install. The way these panels put out, I may only install 2, and might keep the other 2 as add-in portables, or make another system for somebody. These kept us in heating, lights, TV, refrigerator, and all the rest! Temporary battery pack is 6 12v 100 AH AGM batts. wired in parallel (they are freebies) plus the standard coach battery on an AB switch. Batteries never went below 75-80% of 1/2 rating! I have a 3kw Samlex pure sine inverter. Knowing my limited battery bank, I do not run heavy loads! I also use stuff as if connected. (Except AC, of course!) In fact, I was charging some of the others in our group's batteries after mine reached full charge, usually around noon. I am hoping to get my #6ga wiring from my basement to my panel location during the holidays. have not quite figured out my mounting so far, but I have ideas. Hopefully, I get my unit back from the dealer, as the sides are out of adjustment yet once again!

Kenny, yea, he has beaten a few up, but he avoids really slinging them too far in the dirt. I know some of whom he speaks, have seen their "work" at top dollar, and have to agree with him. For what these people paid, even compared to what I am getting together, they are getting junk at a far higher price than I am doing. However, I will add....that I am acquiring my stuff a piece at a time, getting decent deals on the stuff, and am doing all the work myself. I have to add....for what they paid, they SHOULD be getting better than what they have. The installers insist on using 10ga wiring from the panels to the controller, and #8 from the controller to the batteries. While that might almost work ok.....(not) I am getting a lot more just by by using larger wiring. During the install phase, the wiring size upgrade is CHEAP and most definitely worth the price of admission. I am installing #6 from the panels to converter, and 1/0 to the batteries. every 10th of a volt to the batteries makes a big difference on how well they get charged! This equates to battery longevity. I had a smaller 150w (2x 75watt) setup on my pop top trailer and a PWM controller, but used large wiring practices. I typically got 7-9 years from my batteries. Even when I replaced them, they worked well enough to run my solar night-lights I have around the house for several years beyond that!

Solar panels. How many needed?

The controller I am looking at, allows up to 2ga from the panels to it.

So that's what mine will get. The biggest that will fit the controller.

Also 2ga from controller to batteries.

4/0 from inverter to batts.

Hi Kenny! What controller are you going with? Just curious! After I read your post about wire size, got me to thinking that 1/0 was a bit small.....re-read my post, and went out to look at the wiring included with my inverter. Mine is also 4/0! I bought my Samlex 3k used, but pristine condition from CL, traded an old 600 watt Honda Genset for it that I bought 30+ yrs ago before solar on my tent trailer. A testament to Honda. That has sat in my back garage for over 20 yrs! Drained the gas, put in new, started up on the second pull!

Also, one of the guys I camp with, has a 475 watt solar, uses 46voc panels, so gets more amps at 12 v, a 1kw Honda, and 6 battery setup. He runs his AC as needed during the day, and is able to break even in the charging department. However, he took the AC from his roof, and converted his AC system to an ultra efficient split residential type unit. During peak solar, he does not even run his generator. He does Hvac for a living, so...... I camp mostly in the mountains or desert camp in the cooler months, so rarely need the AC.

I will be doing the outback flex max 60/80. Running the panels in series for high voltage/low current.
I know, with having high voltage, I could run smaller wire.. But why.
It accepts 2ga.
Magnum hybrid inverter.

I'm not a fan of heights..
Something about having 300lbs come crashing down....

So I will climb up a total of twice.
Once to measure out available solar real estate. Once more to install them. I will not be tilting the panels, so might toss an extra one up, to make up for not tilting.

I know though, especially being up north, tilting would make a big difference.

I am still debating my permanent install....to tilt....or not to tilt! I am thinking, if fixed, leave 2 to be portable and tie them in as needed. Thinking, 2 of each each in series. When the portables are added in, they would be in parallel with the first 2. That would keep my Voc below the ratings of my Morningstar.
