I have my 4x100 watt solar panels wired in series and typically get less than the rated 5.29 amps at between 65-80 Volts. The system works well with my mppt controller and I have no complaints.
I have however been lazy/busy and neglected to install a Circuit Breaker on the wires going from the panels to the mppt controller.
Looking at low voltage DC breakers on Amazon I see some single pole ones and some double pole ones
I was under the impression that double pole breakers are used for 220 volt connections which have two hot wires.
1 Would you please help me understand what the trade offs are between low voltage single pole and double breakers such as these?

2. What is the appropriate size for such a breaker in my application? 6 amp? 10 amp?
