The solar panel is only 10 watts, so less than an amp. I leave it plugged into the navara when im not using it to keep the battery topped up. Sometimes i dont start it for 3 weeks or so.
 
I've been thinking of doing something like this with my boat. where did you get the panel from & have you had any problems with it?

thanks for sharing.
 
I sourced all the parts i needed from jaycar & made it myself. You can buy a premade kit from supercheap in 10 or 20 watts. Solar panels are dropping in price every week at the moment. So the ones from supercheap could be a bit pricey. I have had no problems so far & its been there for over a year. Also the panels from jaycar have a 10 year warranty i think.
 
looks like you have one of the old type on/off regulators. a PWM would be better or a MPPT if they make one that small.

i run the same solar panel but a morningstar PWM controller. wired in permanently to my other vehicle. trouble is shading, it doesn't get the sun enough to keep the battery fully charged all year round.
