OutEquipro 12v AC on front shell

[robtherod]

I just finished installing a Outequippro 12v ac on the front shell of my 3225 tandem the year 2000 trailmanor. I still have the original
120 volt on the rear shell. I also installed 1200 watts of flexible solar panels on the front shell too. I also have 3-200ah lifepo4 lithium batteries and the original shore inverter was replaced with one that will charge lithium batteries. I am using 4- gauge wire for 12v ac to battery bank. The weight of the 12v ac and solar panels is about the same or a little less than the 120v ac in the back. As long as there is direct sunlight the solar & battery system will run the 12v ac 24/7

How's about some pictures of that roof? I had planned on just replacing my AC with a 12v unit. I never considered just adding one.

2- HQST 60A mppt charge controllers ( 600 watts per controller) for 1200Watts total.

What solar panels are you using? I have 800 watts and it takes up a lot more acreage than that.

 

[robtherod]

Similar to these, just a different brand that was on sale a year ago.

I'm scratching my head in agreement with Wavery's statement.

Have you had a chance to test the panel wattage output yet? The reason I've asked is the 200 watt panel that you referenced is only about half the size of each one of my 100 Watt Renogy flexible solar panels.

I don't understand how your panels are able to be rated at 2x the wattage at half of the size. That'd be 4 times more efficient.

Perhaps I'm looking at it wrong, but that doesn't seem possible.

Sadly, an Internet search turns up numerous reports that GCUSSZ's claims are not true. They exceed the known physical limits of silicon panels by a wide margin. As Rich suggested, if you measure the actual output voltage and current of one of the panels (or all of them) on a bright sunny day, you will find their actual capability. Though they still sell panels through 3rd party vendors like Amazon (which would accept a return), their web site is gone.

This is not to say that the panels are useless and don't work. They apparently do produce electricity - just not nearly as much as is advertised.

 

[robtherod]

Your right, I just took it for granted what they advertised.I haven’t checked to see what they really put out I been working on the trailmanor inside my garage and haven’t pulled it out to see what they actually put out. I was just amazed of how small they were to put out that much. I forget companies will say anything to make a sale.

Due to the ridge, curvature, and obstructions (AC unit, vent, and TV antenna) along with thermal and weight constraints I was only able to install 400 Watts of flexible solar panels on the front of my 2922KB.

I have another 600 Watt rigid array on the rear, as I have no space constraints there other than the shell overlap space. Weight becomes the bigger problem, as the lift arms and the torsion bars have more to deal with as the added weight approaches the weight of an AC unit. Not damaging the ridge (crown) of the roof is as equally as important as not creating so much more of a rear weight bias on the camper that trailer sway becomes inevitable during tow.

The weight bias dynamics of your 3325 will certainly be different, but keep those things in mind as you're working towards running an Air Conditioning unit from renewable energy.

This is what 800W looks like. Each panel is 36' wide x 48" long. The physics is pretty much the same for all PV panels.

 

[robtherod]

?

 

[Bill]

Right, Wavery. For reasons involving physics, the best of today's silicon solar panels can generate about 28 watts per square foot of panel surface area, measured at noon, in bright sun shining straight at the panel. So the user can measure the active area of his panel, multiply by 28 watts per square foot of area, to find the best possible answer. The actual power will usually be a bit lower, but never higher.

Each of the panels in your photo measures 36" x 48" = 12 square feet of area. Multiply that by 28 watts per square foot, and the result is 340 watts per panel. Just about what you said. Anyone buying panels should run this simple calculation as a check on what he/she is buying.

X2 250w SunPower residential panels. I had to adjust the front torsion bars for the extra weight.
