Panel limit per string

Quick theoretical question on the max panels you can have per string for a Solis 6kw hybrid RHI-6K-48ES-5G.
Here's my setup:
String 1 - 12 x 335w Qcells all black G9 - max voltage around 400-410v
String 2- 9 x 335w Qcells all black G9 - max voltage around 300-310v
I checked the Solis designer but they don't have this exact panel on their list so I picked the closest 330w one I could find there and it's telling me max panels per string is 13 which doesn't make sense to me if each string can take up to 600v
Was thinking of maxing out string 2 by adding 5 panels to the back of the house roof but apparently I can only add 4 as the Voc value above goes over with 5 panels but I
Does that actually make sense? I'm thinking 5 should work as well as these panels would be N facing and all existing ones are S facing.
As you can see the actual Voc spec of these panels is 40.78 so 14 panels x 40.87 is 572.18 which is still within the 600 limit. Which probably means the designer is wrong as it does not have this exact panel spec on the list.
Questions:
- Any reason why I cannot extend string 2 to 14 panels?
- Will the 5 extra N facing panels cause any issues in the bad months with startup voltage, keep the S facing ones from producing early? These 5 will all have optimizers on them.

12 one string and 14 on the second.
Yeah the voltage spikes when going from clouds to full sun which makes sense.
But as you can see the current 9 panel string hovers around 300 with the odd spike (yesterday to today)
And this is the current 12 panel string which hovers at around 400
If you can read it, the compression on boards is an absolute joke
