Stus-List Re: Another Solar question
Just to clarify some of the half answers posted previously: The wires from the panels to the charge controller must be sized to handle the short circuit current of the entire array (additive if parallel array). Because the maximum current under normal conditions is often ~95% of short circuit current, it is essentially impossible to fuse this side with the industry standard 25% safety factor without having the fuse blow prematurely under normal conditions. The most critical fuse/breaker is on the battery side of the charge controller as the battery bank has a much larger potential to dump high current in a short circuit. This fuse/breaker should be mounted to the charge bus (if available) or as close as possible to the battery. However, it is not a bad idea to have a dual pull breaker between panel and charge controller sized at 10-15% > short circuit current. The main purpose of this breaker is to be able to safely disconnect the panels for maintenance or replacement. To the original poster: How large is your battery bank and how old is it? Lead acid or gel? How large is the solar panel? Knowing these paramater can help us narrow down the likely problems. My guess, is that the most likely cause is you had days of cloudy skies after the hurricane and weren't getting any charge. Or your battery bank may be small or aging and unable to accept a trickle charge anymore.

Stus-List Re: Another Solar question
My 175w and 50w are fused for the gauge of the cable, directly adjacent to the controller. This is per the renogy manual I believe. 12 awg solar cable would be likely fused at 20a (assumes 105deg rated insulation) which at our 20vdc would translate to a BIG 400w panel. (C&C 65?) These bigger panels are typically 48vdc I believe so the current stays modest. anyway - no need to fuse at the solar panel. The batteries are connected in parallel with copper bus bars and the positive wires are protected with cube fuses at the battery.

I have that end covered. Proper fuses right at the battery terminals. And the solar panel is tied to the controller, not the batteries themselves. But there is some 25' of cable from the panel to the controller and I always wonder if that part should be protected as well. The solar panel is only 50 W, so it cannot produce too much current (and too much heat). But I wonder what it the proper way to connect it and protect it.

Stus-List Re: Another Solar question
I use a ~ 30 watt solar to keep my batteries topped off without using shore power even when it is available. It is wired directly to my start battery and my ACR keeps both batteries topped off. My question is should I put a fuse in the positive output from the solar controller—IIRC it has a MPPT controller—to prevent a disaster in case a short develops anywhere in the panel/controller/hook-up/ etc.? If so, about what size fuse?

And I had to keep them off for the week because I couldn't get back to the boat, and the batteries went down to 11.4 I guess running the bilge pump all week. I put the panels back up and I'm getting the voltage out of them but the victron is not charging the batteries. Would this be an indication that the batteries charge has gotten too low and that the Charger won't start the charge?
