Hi, i have a 250 w panel on my caravan with a 21.7 Voc and 17.5 Vmp. Is this panel suitable for a 100/20 mppt.

Hi Edge. Yes, that would be fine. Note that the mppt won't kick off until it sees a 5V difference between Vbat and Voc, but once started Vmp comes into play and 1V diff will keep it going.
That shouldn't be a worry except in v poor light conditions like at dawn, etc. Yeh, you've picked the right one.
