I'm not sure whether this belongs in beginners or advanced. How's that for a spectrum?
My question being: Is there a reasonable expectation that panels in an off-grid application are ever in a VOC situation with an MPPT charger?
Same BTU's but the infrared in the ceramic doesn't "see" the air although it will radiate to other solids like your body. Or so I've heard on the internet.
Are there any small turbine manufacturers that offer a "constant speed" blade assembly? I would think if one were pitched for low wind and speed governed to stay below a selected voltage it would be ideal. Not ultra simple, but not complex either.
My one and only purchase based on glowing reviews from a mildy famous YT creator and testimony on this forum was a certain AIO system. Then I noticed a growing number of complaints. Then mine failed. I didn't get mine from the usual reseller and got zero warranty support. Now I have a one in one...
This has been a nagging question in my mind for some months and I've yet to get a satisfactory answer.
Many in my circles are buying solar generators for backup emergency power. However, the lithium batteries in these units are suppose to be stored at less than 50% charge. Is it then the case...
Clearly not. ;) My frugality generally precludes me from consuming the Kool-Aid. Also, I am not the type to orgasm over an included phone app. However, If I were trying to establish a "signature" name-brand, I would not want to follow up the myriad of Growatt problems with a part II. Seems...
Everything is relative. It also depends on the internal resistance of the cells and their sums in each bank... the age of the original bank... blah, blah, blah...
Better? Probably. Enough to be concerned about? Probably not.
Not sure what you mean by exponential curve. Are you talking about the power output drop over the half-life?
So residential sized units that were grid tied could be viable?
You have existing solar infrastructure on the property. Now that you have invited vampires across the threshold, are they requiring you to remove the existing panels? Are they requiring you to have electricity on the property?
I have read that using lithium batteries with a built-in bms will smoke your alternator when the bms disconnects from the vehicle electrical system at full charge. I cannot verify this.
You might look into capacitive level sensors. I built one to auto fill an inground pool, but they are available from industrial suppliers. Might be a cost effective option.
Thanks for the response. My system has always started charging long before VOC is reached, thus pulling down the voltage. Do I just have awesome charge controllers?
I'm usually charged by noon as well. This time of year my energy production starts to fall off around 4pm though. I am absorbing/floating at 3.57ish for 3-4 hours a day. I do have a DIY 55ah li-ion 7s pack tied into the mix that wants to be at 4.2v, so maybe I'm not floating at all.
If I had a username name and cargo trailer like yours, I might be only using said trailer on weekends and such at the track. But those kinds details may make a difference.
Best to avoid the great plains.

The paper is a synopsis of a variety of tests on different lithium chemistries. It includes several on lfp. Here are a couple of excerpts:
Italics and bold added in conclusion for emphasis.
I'm not any more informed about about short term floating from this paper, other than some kind of...
The CCP controls the pseudo capitalism in China. There is no unauthorized competition in the marketplace. Only a high level party member could give you the answer. You won't get it here.
You might try FB. This client found me on a local group, wanted it electrified, and couldn't get anyone else to even look at the job. The bottom is a little store and the top is a bar.
I don't remember the brand. I believe it is of asian origin. The OM/installation manual was very sparse in information. I'll try to get a make and model next time I'm there.
