Huh, your numbers are weird. 22x980Ah of 3.2V cells would give you over 60kWh.

And the price of LiFePo4 continues dropping, it is not a good deal if your cells are aboe $80 per kWh (which at 22kWh should be below $2000).

Fuck. This is what I get for posting on 3 hours of sleep. My hallucinated bullshit came out so close to actual that it looked correct enough.

3.2v nominal per cell, 305Ah capacity: .976kWh per each. Call it .98. Not 980Ah, but 0.980 kWh.

.98 * 22 = 21.56kWh total pack cap.

*0.6 = 12.936 kWh available before conversion losses

We burn about 11kWh daily, so there's about a day in a full battery. Spring/mid summer worked well, but lately we aren't managing to store enough to get through the night, so I will probably add another 10 panels (5s2p) once I can find a grand I don't need.

		I knew the numbers had to match something! Anyways, thanks for sharing. And please take some proper rest, you protect the batteries using only 60% capacity, but allow your body go below 0%. I'm pretty sure thats out of spec.
