I have 20 Santan used solar panels rated at 240W each. I would like to create two strings of 10 panels each to hook up to GROWATT MIN6000TL-X inverter. In order to satisfy electrical code, I need a DC Disconnect device between the solar arrays and the inverter. However, should I use the DC circuit breaker instead because it offers better protection in case of power surge. Please give me your feedback.
