250/100 more panels?

Hello, im new here and i have a simple question. I have a 250/100 to load my 14,4 kW-24v-lifepo-battery. I have 6x435panels (2s3p) which is only 2610w. But the 250/100 could handle about 3000w. Now i have more available space on the roof for 1 more panel. Ist there any way i could connect that one more panel to the system?

And If not, is it possible to connect a 75/15 with the 250/100 without problems. How do they connect with each other?

Thanks for helping

Sebastian

@Skateboardsebi

There is no way to have uneven strings on the 250/100. You would need a separate charge controller.

If they are both programmed the same they will be fine. Do you have a GX? Or a raspberry pi?

No, no GX, no raspberry. But do you mean, if i set the same parameters i can just use them parallel? The chargers dont have to be connected?

If they are set to charge to the same voltages they will be fine as individuals.

They will run with their own internal charge cycles.
