Your replies are very helpful. I have my PV panels (six 325W panels), I'm inclined towards the Nissan batteries, I had planned a heating pad under the batteries, I was thinking of using a single or several small fans like the ones used on servers to move air through the enclosure in summer. I...

I just bothered to read the power bio under your post and you might not know everything but I'd guess you know enough. So then I went back and re-read all your posts above, feeling stupider and stupider as I went. The conclusion I've come to is that the biggest piece of work that I have left...

I'm 73 and not used to being new at anything. However, there are language issues that I don't have solved yet. You guys are speaking in amp-hours and I'm thinking in watt-hours. I'm pretty sure those two things are translatable. If I've got the math right a 280ah 12v battery is 3.36kWh which...

A couple years ago I picked up six (6) 325W solar panels hoping it would be about the right amount. Since then I've watched many of your videos and still think i might work but let me give you details. I had planned to buy a wrecked Nissan Leaf to harvest the batteries but I might not need...

Remember that you might not want to keep lithium batteries in the same structure you sleep in. If they are "fire free" 99.999% of the time that's not good enough for sleeping. Check Will's comments on this. So, assuming your batteries are going in another structure and you can afford a very...

If I use Nissan Leaf modules to build a 48V battery what sensors and controls will it require?

Cost.

With some silly zoning issues I'm allowed to use an external generator but I may not have a permanent solar system. My array will be quickly removable and all my equipment and batteries will be in a very small trailer that is mobil. The cabin will be "fed" through a generator cable to and from...

What does that 80% refer to? I see these percentages in the ads and know that it has something to do with being used up but what is used up, the number of cycles usefully left in the batteries or the voltage or wattage or amperage...? I can't associate the word capacity to anything meaningful...

Better can be the enemy of Good.

Would I be understanding correctly that because watts=volts x amps that a reduction of ah would not be one to one when looking at kWh but a loss in the same direction?

Also, the higher the voltage of the battery the proportionately less a reduction in ah results in a loss of kWh? I used to be very good at math but that was a very long time ago and I'm "rusty".

Thanks, I was busy trying to outsmart myself while simplicity was the path forward.

My battery bank will, probably, use seven modules and be in a very small power shed outside my cabin. I've been told that these batteries are relatively safe, but fires have happened, so I was planning on keeping them out of the cabin. Each winter we have a day or two that gets down to zero...
