Thanks for specs! 60A + 1300W string makes sense for 1 hashboard. OR-ing just means 2 DC sources into 1 load. For Nigeria where we have 1800W+ sun, I could run 2-3 hashboards that way. Will try with a blocking diode to protect MPPT. Appreciate!

I'm not sure what OR-ing is. I haven't measured any back feeding to the charge controller, not sure how I would do that, I don't have very much measurement equipment. The charge controller is 60amps which is good for one hashboard. The array of panels is a string of 4 adding up to about 1300w.
