I haven't used the Ecoworthy, maybe Jim will chime in. How big is your battery bank and do you have multiple banks??

I haven't used two yet but i will be ordering a second soon. Having two will work better for me since my panel are not matched up and would confuse a single controller. It also allows me to charge two banks at once or I'm hoping combine them on one bank.

On combining them, maybe foolishly but I'm assuming both controllers will react to the voltage of a single battery.

I currently have only two wet cell batteries. I'm thinking about adding two AGM batteries in my TorkLift battery box. If I do this, separating the controllers will be nice. I may not even need the second two batteries.

Finally got the solar panel installed.

It is adjustable for up and down on the front by a 1/4" pin with holes every two inches. I can angle it down quite a bit for aerodynamic wind flow.

I haven't wired it yet. Maybe in a couple of weeks when I get more time.

Nice work! I see you basically built another frame under the module's aluminum frame. Also, added a cross member in the center. That should all give it plenty of strength. IIRC, these bigger modules are wind rated to some kind of hurricane scale and that is typically mounting with only 4 attachment points.

You may have to swap out the front windows with some mirror glass to get those extra watts from the reflection, lol.[emoticon] As built, you should get some additional reflection addition, if aligned into the sun right.

I think you're going to really like solar, if you haven't tried it. I'm seeing really good battery health using mine. Also, no generator and all the nonsense that goes along with that (if you have a big enough system). If you're going with 500w of modules and 400AH of battery bank, you should really only have to use a generator for AC, if necessary. I'm still looking for a cooling option that can be used with a small solar system. Hydronic may be the answer, it will take me more time to figure out.

I was thinking about adding the other panel at the open area on the left hand side of the trailer under the cab over part. When I would swing it out for usage it would provide more shade on the left side of the trailer. I really don't think that I will need the second panel since I can't run the AC by adding the second one.
I still haven't ordered the Eco Worthy controller, but I probably will next week or so.

Very nice job! Can you take it off if you wanted to go portable?

On the Eco-worthy, it would be a few dollars more ($115 instead of $102) but you can order it from a seller with US stock and get it in a week.

last night I was think that in my situation I could use the fresh water tank for cooling. Even when it gets hotter up there during the day, it gets cold enough at night to use the furnace. I could use a radiator of some type outside and cool the FW tank considerably and then use a second exchanger in the trailer during the day to cool things down. ( I know my usual low tech ideas)

The entire assembly can come of with the removal of one pin. The solar panel can come off separately with the removal of two pins, one in the front and one in the back.

Jim, if you had enough cool water you could use a heat exchanger to get some cooling from it, but it would take a lot of water. There are cooling systems that turn water into ice during the night time (cheap electric rates) and use the ice for cooling during the daytime.

There would be other issues too like the noise a pump will make at night not to mention the power it would use.

The Eco Worthy MPPT controller came in today. It appears to be well made, but time will tell. I would like to mount it outside near the batteries and solar panel. Has anyone used a water tight plastic box with a hinged lid? If so, what did you use. I don't want a box that conducts heat.
