Hi. I live in a small village 30 miles above the Arctic Circle on the North West coast of Alaska. Access is by plane only and our electric grid is an island. Our town power plant has a 20' shipping container 1 Mwh worth of batteries they tell me can power the whole town for 30 mins. We still have had a couple outages but nothing like what we have had in the past. the battery is built by Saft. I got to tour it a little while back and was blown away. was in such awh that is didn't document it very well. I plan to go back and do a proper write up as it's pretty cool.
Anyways... my project is to build a solar system for my triplex. I starting with a 13 Kwh bank with a 3k server room UPS to power the common area lights, security lights and cameras for now. I'll also tap some of the power for my shop also located on the property.
The plan is to get the battery pack built and operating with grid power this winter and install solar panels next summer.
I have obtained 1200 panasonic NCR 18650BD cells that Jehu told us about in this live Youtube https://tinyurl.com/ybay7ylo
They came in 20 cell packs.
Some of the cells have deep scratch that penitrates the wrapper. They will need re-wrapping
Started the testing of the cells using 5 Opus 3100s .5A discharge/charge.
After 180 cells through the testers here are the numbers so far:
Max mAh: 3263
Min mAh: 3024
Avg mAh: 3175
Max IR: 144
Min IR: 48
Avg IR: 71.8
Will update this post as progress is made.
