It's funny how complex things seem as a beginner. I hope I can look back at this post 1 or 2 years from now and laugh at how clueless I was when writing. I was over-eager. I couldn't see past the $0.13/kWh pricetag.... and now I have 16.5 kW of LiFePO4 power. You'd think I'd be happy, right...

I was able to track down more details about battery packs I acquired but could not figure out how to use. Each pack comprises 56 prismatic cells but looks like it can be broken down into smaller pre-fabricated sections for 28. With buss bars in series: Attempting to charge to 3.7V when I...

Is anyone aware of an alternative company to Unbound Solar? Seems that their service would be a great fit, but, according to the rep. I spoke with, they require you to order all parts from them exclusively and you must order a complete system. I'd just like plans and some help through the...
