Most often the alternator field potential is reduced in better systems.
Otherwise after battery equalizing (in better built systems) a shunt
type load diverter is used. Often you can use the extra power to move
vent air and heat or cool a building.

All depends on the potentials you're working with. If you're using lower
dc voltages to the battery bank... simply use one of the modern solar
charge controllers like something built by Trace (now Xantrex or something
like the Xantrex name).

Yes, if you want the system to work properly and last more than a few

I do both all the time but don't often get on this group anymore. You can
contact me direct through the below web page email contact icon and I'll
try to provide help as time allows.
