Hi all. I'm using Taixi MCB breakers for my solar panels which will connect to my pair of EG4-6500EX. I'm using 4 strings each comprised 7S (505W each) panels for each MPPT for each of the inverters. The MCB breakers are 25A 1000V and can break both +ve and -ve poles. My panels have a Voc of 51.9V. My question is this....if I'm using circuit breakers (also using PV fuses as well), should I still use solar disconnects such as the ones sold by Signature Solar https://signaturesolar.com/dc-disconnect-rooftop-isolator-switch-by-imo/
Thanks.
Thanks.
