  1. Do you think you miss out on some precious sun considering they are only mounted on the one side and they are fixed and not able to angle them for different seasons?

  2. Love the video. We just installed a system for our off grid place. We used a lithium, battery from a Chevy Volt. Check out our channel for a video if your interested.

  3. Excellent video! I love solar power, cabins and being off grid and you have done an excellent job sharing your experience and knowledge. My $0.02 worth for somebody building a similar system from scratch would be to install industrial agm batteries indoors mainly because batteries do a lot better in the same temperatures as are found indoors and agms do not out gas. I can't afford new ones but I found that there are a lot of real good used ones with a lot of life left in them available almost everywhere real cheap. $0.50 per amp hour for an industrial 12v agm battery that tests above 13v after sitting for a few weeks is a good investment. I mix and match different sizes with no problem.

  4. My husband and I are thinking about solar for our 900 sq ft camp…who would you recommend, and what would be a good wattage to start out with? Our camp is about 25 mins north of Huntsville.
    Thx for the vids and the laughs! Pls keep them coming!! Val and Chris.

  5. FourZeroFour below commented on that the "not enough charge" could cause a problem–can someone explain this is more detail?  And what types of battery could alleviate this problem?  Thanks.

  6. Nice cabin. Perhaps I missed the reasoning somewhere but it seems you could have used all the PV panels. It seems to me you could have kept everything at 12volt as you are not doing a long run. Charge controllers for 12v are cheap and the inverters for 12 volt are much less expensive too. Plus, since this is an off grid property that is not outfitted yet, your options for appliances are not set and such are widely available for 12-volt DC. No need for an inverter at all except for those few things that really require AC. Tons of 12-volt stuff available online and even at a local truck stuff if you cannot wait.

  7. Thanks so much for letting us know how you think about things. I put together a 600W panels system with the 1500W inverter and 600 amp hour batteries -AGM's
    It's tough in the winter time, but plenty of juice in the summer. I use it as a back up for my house. And off the grid system. Much simpler to put together than what you have.

  8. You can definitely charge a lead acid battery 'too slow'. Not having enough charge current (especially in a solar system) could cause lots of problems. Not a good enough charge in a day, which could lead to sulfated batteries, for one.
    Nice batteries though. Bet those cost you a pretty penny.

    AGM batteries are not necessarily cheaper. And for an inhabited location, I'd choose flooded batteries. Better longevity with proper maintenance, and more forgiving of improper charging if they're at least watered.

  9. Hey man, any reason why you didn't go to 2 strings of 5 panels each? apologies if you cover that in the video, i had to stop before i finished it.

  10. We seem to be at a similar knowledge base with off grid solar. I'm working on a hybrid system for my homestead that is quite a bit more complicated than off grid. I would absolutely look further into your battery situation. Running bone dry means sulfation. Perhaps look into a desulfator in the hopes you can repair some of the damage that's been done. Nice vid. Thx.

  11. 48v sistem is way more efficient than 24v or 12v
    All your sistem could exchange for tesla powerwall2 is probably the same price with no maintenance inbuilt inverter charge controller and transfer automatic and awesome Android app….all in one and probably 10years warranty…
    Try to calculate this….
    Anyway your sistem is also awesome sma inverter are like buy once and hold a lifetime…. 👍
    Desulfator would be a great way to prolong the life of battery's BATTERY EXTRA it is very good desulfator…. 👍

  12. You have very good inverter and good charge controller….
    Tri star charge controller have model without fan…..👍

  13. This is incredibly informative, moreso than other solar power vids. I can see that these systems are beyond me, but if the time comes I need one, I will take your advice!
