I'm switching a single
8A panel with a 15 amp SPST switch at the helm
. The switch (and a fuse) will be on the battery side of the controller. At the helm
was the most logical location for us. When at the helm, prior to turning the ignition key, I can turn Off the solar
panel feed and charge from the alternator
charge. When time to sail, turn off ignition and turn on Solar
. I've read on this forum of alternator
cycling, due to it sensing the solar feed, potentially causing premature failure of the alternator. Our alternator is very old so not causing it undue stress was/is a consideration.
