Is 233V 19A in each input (3pc MC4) ok? Smart Solar MPPT 250/100 48v!

I have 9,9kW panels. 36pc 275W Voc38,7V Isc9,17A.

That's all for Off-grid:

Unless you never get frosts, your array will go over 250 volts at temps of 0c (32f).

Please use the Mppt Calculator.

So long as temperatures never caused the panels to exceed 250v the controller could handle it.

You would however be unable to use a lot of your solar capacity as that controller is only rated to 5800w @ 48v

I would consider adding another controller or reducing the number of panels. 24 panels (6s4p) would be the maximum I would connect to that controller.
