While investigating the wiring
on the 12V system on my recently acquired boat
I discovered that the two solar panels
were connected in series, the current
then passing through a regulator
and directly into the house bank of batteries
. Is this normal or desirable? I had assumed the panels
would be wired in parallel with the regulated current
being directed to the Cole-Hersee selector switch, so that you had the option of charging
either the cranking battery
or the house bank.
My experience is very limited here and I would welcome any advice.
