You can always add that battery in later.
I would also have your electrician test your rapid shutdown once he gets the inverters swapped. I'm not sure what system Tesla uses, I installed the AP smarts to match the AP Smart transmitter in my inverter. The dark start battery actually keeps the shutdown from working. SunRun just created a similar set-up at their training facility, but can't seem to replicate my issue. I did end up installing a toggle switch on the hot (red) wire from the dark start battery to the inverter, which does allow me to be code compliant. Without this, when I hit the RSD AC disconnect, the PV output would go to 0 however I still have open circuit voltage at each panel. If you have a separate DC RSD, this may not be an issue.
I have still been struggling to get my HIS registered to FordPass, but apparently they have a new system.
I would go ahead and e-mail ASAP once you get things up and going, or maybe even a little before.
