As long as you have a good regulator and a decent solar panel (more than 30
watts) I can't see you having a problem.

Without the regulator you could over cook the batteries.

A friend of mine told me the best way to keep your batteries alive during
long periods of inactivity is to leave a light burning on your boat, but not
one that is more powerful than your solar panel.
This way the battery is continually cycling. During the night the light
burns energy out of the battery and during the day the solar panel puts the
charge back into the battery.

It just keeps it going constantly.

I don't know if it is a good thing or not, but it is what I was told.

Best regards

Hi, Could I leave my 30 watt solar charger and controller hooked up (and
all
electrical) for the winter to keep the batteries topped u? It gets cold
here but not alot of snow so the batteries should stay topped up, or is
the
cold more of a problem on the batteries?
Thanks Richard
