[RE-wrenches] Need some help

Mon Jun 7 13:03:12 EDT 2021

For the record, though, the recalls came later, mostly with 
polycrystalline 72-cell modules, 160s and such. The 75s, 85s and 90s 
proved to have few failures. I'm still running my home off of 18 BP90s 
(one's an 85) and that 1,595 watt (original rating) from 1997, and it 
still runs around 1,300-1,400 watts IRL. I'm not defending BP - they 
went down in flames and for good reason - just making a distinction 
between early and mid-2000s.
