Can I use the SMA SB7.7-1 SP-US-41 Sunny Boy Solar Inverter on a 9.8 kW system?

Yes, you could if you had two inverters in parallel. You can also oversize the Sunny Boy 1.5 times on the DC side (when correctly following the installation manual), meaning that you could have up to about 11,550 watts in solar panels. Keep in mind though, that in this scenario you will still only get 7700 watts at any given time.
