I've been chewing up zincs lately, so I thought I'd try unplugging the boat from shorepower for a bit until I can redo the wiring
Anyway, I installed a solar battery
'maintainer' similar to this one.
SUNFORCE 5 Watt Solar Battery Trickle Charger at West Marine
THe panel is wired to a fuse, has I think a couple of diodes inline and is made to wire straight to the battery
. However, in bright light it puts out 21v, which concerns me greatly. don't I run the risk of cooking
the batteries at that voltage? These panels
don't seem to require a controller, but would one work or is the panel too gutless to even try?
I just want to get by til summer when I can do a proper solar
install, and want to spend the least money
possible. (so no new batteries would be good
