Why does the MPPT calculator not suggest the MPPT 100/20-48 (anymore)?

Q&A and troubleshooting

We want to expand our solar installation with some panels and we want to connect the MPPT’s directly to our 48v battery system. We already own 6x JA Solar JAM54D41-450N panels and want buy some more (not sure how many, yet).
1,5 year ago I’ve done the MPPT calculator with these parameters and then it suggested the 100/20-48 if we put two panels in series.

Now we want to continue with the installation I filled out the parameters again and now it is not suggesting the 100/20-48 anymore… Can anyone tell mee why?

OK I think I figured it out…. At higher temperatures the start voltage is under the specified Vbat+5V…
Let me be a little more clear about the goal of these extra panels:
We actually only want to use this installation as extra power at days with less sun…

Can this still be a match if it is not a problem if this installation will not be needed at hot days?

Our environment here will have 25+ degree days only when we don’t need the extra power.
