The thing that strikes me about that is the maximum (zero current) open circuit voltage of 80V on the panels going tob a controller with a maximum rating of 100V. That just seems too close for continuous use. I'd want ~50% headroom .

Could you use it? Probably. Is it prudent to move up to the model with the higher rating? Probably.

Remember, their calculator isnt giving minimum spec, itbis giving their "recommendation". Mine would be the same.
