Voltage drop musings [RE-wrenches]

[Joel Davidson]

Hi Steve,
If people got to know Backwoods Solar and other catalog companies that practice
what they preach, they might be less inclined to make general condemnations.
Keep up the good work. I just sent an email to the group about my system. I
don't want to have to re-wire my system. Just pull out the C40 and replace it
with the SB3048. I trust your judgment. If you think I should get an SB3048,
I'll buy it from you or some other damn catalog company :-)
Best regards,
Joel Davidson
