Adding panels

After combining 3 strings in a combiner box is it ok to put all that power on just one line into the inverter. To give some history, I have a solar edge 10kw inverter and 2 strings of 18 for a total of 36 panels at 280 watts a piece. Checking with solar edge they say I can go up to a max of 12.25 kw and it won't be a problem. I bought 7 panels at 330 and took 3 panels off each of the 2 existing strings and combined them in a combiner box. My question is can I now run the single existing wire that has been combined from the 3 strings and run it into 1 of the 2 existing openings?
