No I am not saying that at all. The AC70 (I have 2) DC input is 58VDC Max, 10A for 500W. Exceeding rated A and or W will not damage the AC70. Exceeding the 58V will.
However the maximum you will get with 4 x 100W panels in parallel is 200W. That will be less as the Voc of a 100W - 12V panel is around 20-22V, until you exceed 32VDC, the AC 70 will charge at 8A this will be 20% less charge again.
My suggestion is wire 2 panels in parallel, the other 2 in parallel for 2 strings of 200W. Then wire the 2 strings in series to double the Voc. Here you will get over 40V at 10A for near 400W or double what you get now.
There are 2 ways to do this, both have the same output. However if you chose to connect each string in series then parallel them, if one string fails or is shaded the other still works albeit 1/2 output.

OK. Thank you. Just double checking.
