Is a switch needed in circuit?

Thanks tattoo, that was my first thought but curious that I couldn't find any confirmation on it. I have the fuses in place anyway.

I opted for a battery terminal mounted switch since I have to be outside to set up the solar anyway, really heavy duty.

tattoo,
Sorry for the delayed response.  To begin with it will not be more than LED lights and water pump.  This is my first venture into solar so I'm taking it slow.  


I did finish my wiring of the controller inside yesterday.  I doubled checked all my connections but when switching the power to the controller I got no response from it.  Would that be normal?  I'm guessing it is since the input power would be from the panels which I did not hook up due to lack of sun.

I'd find/use a test light or voltmeter to determine if the CC is getting batt power. Minimum voltage (in manual) usually required.

Every CC I have owned/used/installed came to life with battery power, some need it to determine 12v, 24v, ... operation.

CC plays well with converter charger (generator/utility power), alternator power, generally left connected 24/7.

Most CC manuals warn about connection order, batt first then panel and disconnect order, panel first then batt, this seems more critical with MPPT vs PWM but the warning(s) are still there, impossible with most suitcase panel that are pre wired to the CC.

Even on a holiday I was not content unless I found the problem.  So, in rechecking my connections i started at the battery where the obvious became obvious.  I had apparently not screwed the knob that connects the two parts of the cut-off in completely.  Once I did, all was well.  Thanks again to both tattoo and rabird foe steering me in the right direction and Happy Thanksgiving.

To be honest I used that cut-off only because I wasn't able to find a suitable switch locally.  I was Intending to replace it with an inside switch when I found one that could work for me.  Most of those I've looked at have the projecting key that looks like it would just be something constantly being snagged on clothing or hitting knees or shins.  I'll take your advice and replace the cut-off as soon as I can. Part of my dilemma in finding a solution for the switch comes from my OCD approach to installation, it has to blend with the interior and not be intrusive but still be robust.   Thanks again for the advice.
