I have a 62v/23amp battery, and apparently I need to put a circuit breaker in-line between the battery and the controller? What size should I put in there?
 
You don't need anything between the battery and controller but most people put a fuse. If you want to use a breaker, then it should be able to take the max amp draw of the controller without tripping.
 
I have this Solar DC Breaker that can handle 150v and 100amp.

Best practice is a fuse as close to the battery as practical. If you don't screw something up, you'll never need it. If you screw something up, it protects your battery from shorting out.
-If you screw up once, replace the fuse and go on.
-If you screw up twice, replace the fuse and start examining your life choices concerning your actions around dangerous objects.
-If you screw up 3 times, High voltage toys probably aren't for you.
-If you screw up so many times that a circuit breaker is worth the cost/effort, you probably don't need to be using tools or be left alone around sharp objects :mrgreen:


You need a fuse sized on the max amps of your controller, plus a little extra. So if you have a 20 amp controller, I would get a 25 or 30 amp fuse. While I use automotive blade fuses, there is an arcing risk, so a proper high voltage fuse is right answer. Check Amazon or Ebay for "FKS 80V 30A" fuses, or what ever amperage you need. Get at least 2
 
People and their opinions.
The OP did not asked what is the difference between Fuse and CB.
He asked What CB should he get.
Why give an opinion to make yourself sound smart by stepping on others?
That's been the issue with this forum lately.
You asked a question and instead of giving a direct answer people treat you like an idiot or straight out call you stupid.
Well that's my opinion anyway.
