Sure, I don't see why not that way you have a fuse also..... I'm not sure how it will hold up cutting it off and no as it's not designed to be a switch.... It's a breaker you asked about a switch........... They are different.....
Thanks for your help. What happens is that right now I do not have much budget. And I do not think it's smart to buy switch and fuses apart. If those are good, I will put a 30amp inline fuse in the output of the 4 panels of 100w that I have connected in parallel. One 30amp circuit breaker at the entrance of the panels to the controller and one equal at the exit, from controller to batteries. From the batteries to the inverter I will put one but 60amp. It is a 700w inverter that I use to light a Mac mini and a fan.
Do you think that configuration is fine? Or recommend something different.
Hi, I would recommend the 50A or 60A circuit breaker. For 3, 100 Watt panels in parallel, a 30A might be tight. With a larger Amp breaker you can always add another panel or two, and still use the same breaker. I have 2, 100W portable panels that I use in winter, as the output power of mounted panels goes way down in winter.
