My DIY solar system will consist of - 4strings of 4- 425watt Panels in series. Each string will be wired to the 2 ports on the 2 MPP Solar LV 6548. Each Positive line will have a 20 amp Breaker and will use 10 AWG PV wire. The wire run to the Panels will be 50-70 feet. This is my Idea any...

I will have a 16s 48 volt 280amp battery pack, this means I think I need a 300amp BMS, can I use a 600amp bms or must it be closer to the battery pack size. If it is OK to use any amp over min what other than cost are the cons
