I got my MPPT controller in and read the instructions (I hope I wasn't treading on dangerous ground here;) ). It says I should put an in-line fuse holder between the controller and the positive terminal of the battery. The problem is it doesn't say what size fuse I should be using. Does anybody know what size??? I have one 250 watt, 8.7 Amp solar panel and a 20A controller and I'm hooking to two 12V marine batteries wired in parallel to maintain 12V. Also, since I'm going to a battery I'm guessing I could get a part like that at the car parts place like Auto Zone, or will I need to go to the RV dealership?
It's sure nice to have a place like this to go for help . . .THANKS!
