Existing G98 system expansion - G99 necessary, and what's the pathway?

Hi all. I have a 3.68kW FIT installation and an AC coupled inverter with battery storage under G98. I run a PHEV which charges when there is excess solar, or from low night tariff energy.

I'd like to install about 3kW of additional panels with another G98 type inverter on a more westerly roof, which will help to smooth out the solar power availability in the afternoon hours, mainly to charge batteries and increase house power availability. However the two aggregated installations would take me over 4kW, and I assume I need to re-certify under G99? I would intend to cancel the export FIT portion and then sell exported energy via SEG.

Can anyone help with the G99 issue - should I apply just for the proposed installation or do I need to list everything I have connected/intend to connect?

Thanks for any advice!

Chris
