We recommend having a dual pole breaker/disconnect switch (switches both the positive and negative leg of the circuit) like this one between your solar panel array(s) and the input on your solar charge controller so that you can disconnect the solar panels from your system when needed for storage or maintenance.

• DIN rail breaker (rail included).
• Rated for up to 1000 volts DC at up to 32 amps.
• Color-coded for polarity.
• Trips fast: the electromagnetic trip system can trip immediately when the circuit is short-circuited to protect the safety of the circuit.
• This DC mini circuit breaker has a magnetic system for effective arc extinguishing.
