Hi all. I’m hoping for some guidance from this forum on the type of double pole breaker I should be using for my solar setup. I have 2x EG4 6500EX 48V inverters and will be using 32x 505W panels. The panels are being configured in 4x 8S strings, one string for each of the MPPTs of each EG4 inverter. The panels I am using have a Voc and Vmpp of 51.9V and 43V respectively. The panels also have Isc and Impp of 12.35A and 11.75A respectively.
Would a 500V breaker be sufficient given that the Vmpp is 43V, which times 8 would be 344V and the total VoC would be 415V? Where I live we don’t have winter so I don’t have to worry about cold temperatures and how that impacts voltage from the panels. I’m looking at the Taixi breakers from AliExpress. Here’s the link below- are these breakers suitable for my application? And if so, should I be selecting the 500V or 1000V breaker. And should I be using the 20A or a different current rating. Thanks in advance for your assistance.
