i have 3 230W 41V panel in series. can i use this as the breaker or disconnect? https://www.amazon.com/ZOOKOTO-12V-...keywords=12v+dc+breaker&qid=1595134839&sr=8-6
Just to clarify that would be 1.25 times the load. The wire size should be matched to the breaker.When selecting a breaker, make sure it can handle 1.25 X the amperage
With 3 panels no breaker or fuse is needed. The wires can handle the full short circuit amperes. Voltage drop is always a problem with solar charging systems. Fuses and breakers add resistance. A heavy duty switch will add the least resistance. Blue Sea makes the best. They also have proper DC breakers if I didn't convince you. https://www.bluesea.com/products/category/11/37/Manual_Battery_Switches/m-Series https://www.bluesea.com/products/category/14/Circuit_Breakers
I suggest being careful with inexpensive breakers claiming high DC voltages. I tried this one, for exampleI recently bought this 2 pole but haven’t put it in service yet.
