[RE-wrenches] DC generators

[Ray Walters]

I never recommend trying to fully charge with a generator anyway: its 
too fuel inefficient.  A good 4 hour bulk charge from 50% back to 80% 
SOC, and then hope the sun shines again.  I usually set the voltage on 
the high side (they usually run the it in the winter), and program the 
run time to 4 to 6 hours  (depends on the generator to battery ratio)  
Trying to do 3 stage charging off grid from a generator can cost up 
around a $1.00/ Kwh.
