I understand what you are saying and agree it is the best alternative. Thanks for that. However, my wire configuration will not allow it as easily as other options, yet.

I’m doing PWM on a late 1990’s Heliotrope constant voltage controller set at 15v (options are -, 14.6, 15, 15.4 and +v). Yes, some would say that is too high but on “float” (15v with .2-.1 amp), I get a single small bubble in each cell every few minutes. Voc is 17-18v.
I think I’ll try the temp isolation of solar from the house batts first.
