I'm an engineer
, but the specifics of this one have me looking in circles as I know nothing about solar panels
panel putting out approx 1W @ approx 8-9 volts.
-Nav kit able to survive for 200-300 hours after being fully charged.
-Nav kit fully functional and being trickle charged within 12 hours leaving excess capacity from the solar
panel for the remaining week.
-Boat will be used for 6-12 hours per week, so the rest of the time the solar panel can be trickle charging
the Nav kit and anything else.
I want to continue with the already working system of the solar panel trickle charging
the Nav Kit. Now I want to put a 12V battery
(like a motorcycle size) to be trickle charged as well. This battery
will supply extra power for a chart plotter.
Some form of regulation and conversion from 8-9V (varying depending on sunlight) on the solar panel to the 12V battery, including some form of monitoring and knowing when to shut off the trickle charge. Also I'm guessing there should be some form of protection for the solar panel itself.
, simple, tough, strong, bullet proof, utopia etc..
Appreciate any advice.
