Good afternoon all!

I was just hoping to solicit opinions on 1 vs 2 Powerwalls - I have an order for one but having trouble finding out if two would skip a subpanel since Tesla thinks I'd have to redesign to get a quote on that!

I have the following:
-6.6kW solar array with microinverters that come together in an Enphase combiner.
-NEMA 16-50
-electric water heater
-electric stove/range
-electric dryer

I don't have an air conditioner or any other major draws, so I can't imagine two PWs couldn't handle all of the above.

Would I save money if I just got two and skipped the subpanel? The website has a "Other electric vehicle are compatible for backup with a minimum of 3 Powerwalls" but I'm assuming there's no reason to not connect the 16-50 plug into the powerwall?

My basic goal is to be able to use the solar panels in case the grid is down and to avoid peak usage.
