I started to reply once, but realized, a potentially multi-page response would be worthless.
Let me boil my thoughts down to this, as someone who still uses CB a bit, GMRS, General Class Ham, having been on Fire, EMS, LEO, and aviation.. all of which use radios in multiple ways,In the end, the radio is the easiest and least important part of comms. Having some idea of what “Spectrum” is, how radio waves propagate, at different frequencies, weather conditions etc.
And a biggie. Radio.. isn’t telephone. It’s not point to point. When you transmit, it’s more like a big sprinkler. If someone 5 miles away can year you in one direction, people for 5 or more miles away in ALL directions can likely hear you, and it is possible, you could be interfering with communications you can’t even hear.
It’s like driving. What you drive is of less importance than knowing the speed limits, which side of the road to drive on, how to navigate a parking lot etc.
But, that’s just me. It’s about community, cooperation, politeness, helpfulness etc.

Access is first. If you cant get there, or around the property, how are you going to do anything else?
P.A. Yoeman had something he called “Scales of Permanence”, which basically said that some things are more difficult to change than others (more permanent), so start with the most permanent, and move to the less (things easier to change).One version was: Climate, Land shapes, Water, Roads, Trees, Structures, Fences and subdivisions, and lastly soil.
An example is someone who gets on the land, and immediately puts up fences, and starts amending the soil. A few months or maybe a year later, they realize, they need to drill a well and do some earthworks to slow down and spread out water (to stop erosion).
Now they have to remove the fences to get the road to where the well needs dug, and all that soil they’ve been working on has to be scraped off to create the swales or other earthworks.
Yes, you need water to live or grow anything, and putting fruit trees, or shelter belt trees are great things, but, unless you are sure they won’t have to be moved or pulled out later because a road really needed to go there to be optimal, or terraces need built for the market garden or such, you may be re-doing stuff, which costs money, time, effort and mental/emotional currency.
Just something to think about.

Wow.. I’d pay $25 all day for those. I’ve got at least 2-3 charge controllers that I could use them with, one starts working at 120v and goes up to I think 250v, and another one goes up to at least 300v.
-
Rereading. is each panel that high of voltage, or are they that high when connected series?
If the latter, why not just connect 1/2 series, 1/2 series, and those two in parallel, dropping the voltage within a safe range, and take that directly to the charge controller? Or maybe a 2nd, charge controller, one for each string, leaving everything else the same?
-
What is the brand and model of those panels? I’ve not seen any over maybe 60is volts. Need to broaden my information base!

Nope, possibly because a video doesn’t need to be posted to 9 groups at the same time. Once is quite enough.

Sometimes, it’s good to just start with something (legal) and see what it will and won’t do by experience. Then if it does what you need, you’re done. If not, then what will it -not- do, and look for solutions. From there it’s just ongoing cycle of observe, solve, repeat.

While I’d prefer not to be internet-connected for many reasons, at the moment, it is a necessity, as I’m not able to be on my property that much, but need to know what’s going on. Fo instance at the moment, I have two small solar arrays. One goes through a Victron charge controller, and one goes through an “all in one” inverter/charger. I can see what’s going on with the All in One via ‘Solar assistant” (and even have some real-time control), and it should be giving me the best state of charge of the batteries, as they batteries talk directly to the all in one, however, all energy in and out of the battery rack also goes through a Victron Smart Shunt, which currently doesn’t talk to Solar assistant.
The first pic is the current status of the all-in-one, including the battery state of charge (Grid = generator)
The second pic is the Victron side, with combined solar, generator, etc going into the batteries.

I’m considering doing another diy battery for the shed to classroom I’m getting delivered. I’ve done one small 12v battery but looking possibly at something more your level. Not sure if I want a bms that has the can or rj485 connections to communicate directly to an inverter or charger directly or not. Been watching OffGridGarage, and his exploits with some of the more feature rich bms’s.

Perfect!

Questions:
what is the dc voltage of your system? 12/24/36/48What is the rating for your inverter, and what is the largest load you need to run, evern for a few minutes?
The reason I ask is, one if the significant differences between lithium and lead based, is the lithium has a bms, even if diy. Those bms’s are rated at 100 or 200amps generally.
1300W on a 12volt system (I used 13 vdc for the calculation) is 100 amps. Meaning, if you ever, much less routinely have total loads over 1300W, you need either a 200amp bms, or two batteries with 100amp bms’s
on a 24vdc system, then 100 amps (using 25vdc for calculation) is about 2500W
Just something to think about. Lead is made to surge hundreds of amps for a few seconds, Depending on the bms and cells, a lithium may go 50% over rated capacity, so a 100amp might go 150amps for a few seconds, then shut down.
It’s not just about the size of the cells, sometimes one needs multiple “batteries” for the amp load.

The main problem with the vertical is the sideways loads on the single bearing on the bottom. The taller the vertical blades, the longer the lever, the more the side load.
The higher the wind speed, the stronger the force, on the lever, then on the bearing while trying to spin. They just wear out faster.
Horizontal turbines, spin, but don’t have much if any side load on the bearing(s). There were a couple of other physics-based problems which have yet to be “solved” thus far, and that I’m not smart or educated enough to remember or understand. I’m all for progress and innovation, heck, love it, but that doesn’t mean everything new or neat, actually works.
That said, at some point, I may get a (horizontal) turbine anyway, but I will do so, fully knowing, it’s an experiment, which if it provides noticeable, or significant output, that is a bonus, but it will go up with little if any expectation, and not factoring it in as a part of a critical supply system.

There is a skete in Grand Junction, TN a bit west of Memphis that I visited a few times. Mother Nektaria (now passed), was probably the one person who was the most accepting of me, under any and all situations. When I finished Nursing school, in my 40’s (RN), I was so stressed, I just called her to make sure the guest house was not in use, and just went to chill. If I wanted to sleep, that was fine, if I wanted to read that was fine, if I wanted to join her in any of the hours or other services in her small chapel, she appeared pleased to have someone help read. Haven’t been back to that church or skete in years now (had to move to care for my parents), but probably miss her more than the actual church. I can’t go to any other (non-Orthodox) service or church for any reason, and feel like it’s actually “church”. Likely judgemental etc, but just how I feel. The quiet, the smell.. Never a doubt it’s a church, rather than someplace a “show” is put on. The only one where I am now, is a very small chapel, that I don’t think has a permanent priest, and is an old calendar, Russian offshoot that I don’t believe is in communion with the rest of the church.
