What size mppt controller do I need?

What victron mppt controller do I need for a 300W or 2 x 170W solar panels charging 2 x 100ah 12v lead acid house batteries that run led lights, water pump, 12v stereo and marine electronics, 100/30, 100/50 or 150/35?

If your solar voltage doesn’t exceed 90v, the 100/30 should work for everything under 400w
