Hi all experts!

I will have 28 panels in two strings (14 panels/string)
The panels are these Blusun 410W panels, pdf link included.
https://www.bluesunpv.com/china-fac...ll-black-410w-shingled-solar-panels_p438.html

Pmax:410
Voc: 46.6
Vmp: 38.8
Isc: 11.07A
Imp: 10.57A

Will it be to much solar panels for the hybrid SUN-10-SG04LP3-EU?
Datasheet Pdf link for inverter: https://www.deyeinverter.com/

And can I connect it in two strings? Cause I see that the inverter has 2+1 but I only made two strings.
I live in Sweden (Gothenburg)

Pleeease! Thanks!
 
Dye 10K:
13kW max PV
MPPT: 2
800Voc max
350-650V optimal operating
PV input Imp current limit: 26+13
PV input Isc current limit: 34+17

Panels:
28 * 410W = 11480W (under 13kW)
14 * 46.6V = 652.4V (under 800V)
14 * 38.8V = 543.2V (in the 350-650V range)
Isc = 11.07A (under 17A)
Imp = 10.57A (under 13A)

It appears the first tracker on the 10K Deye can handle more current than the second.

You could parallel both 14S strings on the first tracker or put one 14S string on each tracker.

In the absence of some compelling reason to parallel them, I would choose one string on each tracker.

Based on my interpretation of the specs, you could safely over-panel by adding a 3rd 14S string, two in parallel on the 1st MPPT and 1 on the second.
 
I love this forum! Thank you so much @sunshine_eggo for taking time and calm me down, was worried I put up to much panels on the roof and would have to reconnect them into three strings. But now I´m calm. ?

I will connect two Mason Seplos Batteries to the inverter. Will staple them on top on each other and paralell them with a copper busbar with measurement 30x3mm I hope that will be enough.

Maximum Charge/discharge for inverter is 210A
