I'm not defending SolArk or their customer service (no personal experience with them), but I always read the specification of the products before I spent my money. Shame on SolArk for not advertising accurately, and shame on you for not doing your homework. We call that paying your tuition...
The real problem to heating with a solar system is getting the heat loss down to something the solar can keep up with.
If your yurt had an R50 rated insulated floor, roof, and ceiling, you would have chance of providing enough heat from solar.
You would need a large array of panels and...
I like Will"s 48 volt battery approach. I understand the concept and think the higher voltage DC storage would be better for me. The used battery packs I have obtained would break down to 36 volt, 72 volt, 144 volt packs. A 36 volt or 72 volt system might be the simplest to use the battery...
I recently ran across an ad for some used bus batteries:
EV lithium-ion EAS battery packs 52kwh
contains 160 EAS lithium-ion NCA type battery cells
EAS 3.6v/45AH/162wh litium-ion NCA battery cells
Dimensions 60mm*232mm weight 3 lbs
Germany assembly for large capacity power and storage
LiNiCoAl...
I have not been able to find any information on the charge-discharge efficiency of the iron edison battery. I have a suspicion they maybe worse than a lead acid battery?
I really enjoyed the late Jack Rickard's EVTV Motors, YouTube channel. I remember him saying, after working with 200 amps on his 48 volt Power Safe 100, "this is no way to run a railroad". He did like the high volt DC concept, and I too agree. Yes, but there is added safety considerations...
Subject : Application of IQ7X-96-E-US
Details : I have a large number of REC 235 PV panels and after looking at the specs for the IQ7X-96, realized that two of my panel wired in series would meet the spec for one IQ7X-96. Any concerns you would have about an installation of this sort?? Cost...
JeepHammer,
Thanks for your reply!
When I looked at the factory sheet of the (45Ah) cells, a new cell has a voltage vs discharge capacity from 4.1 to 3.2. Very little gain above 4.1 and quickly falls off below 3.2 volts. I thought I would try and keep the max cell voltage under 3.9 and...
You might watch the Youtube channel of the late Jack Rickard EVTV Motors. He built several 48 Volt battery systems, but liked the high DC Tesla batteries at 300 to 400 Volt DC.
