Thank you for the information! I have a couple of questions: 1) Can you tell me if Powerwall is capable of accepting 110/120 VAC input from a small portable generator to charge the batteries, such as, during a natural disaster? 2) What's the minimum input level from the PV string? For example, if I am only able to install 6 panels, and the additive voltage on the string is ~234VDC, do I have options? Thanks in advance!

1) no.
2) Powerwall only works with Solaredge inverters and optimizers. I do believe the minimum string size for a Solaredge inverter is around 6 panels, but you'd have to check. I think it is a minimum wattage, so it would depend on how powerful or efficient the panel's are.

Residential 220v IS 110v; L-L = 220; L-N/G = 110v; Some inverters are only 110v since they only have 1 hot leg.

That is great, for suitable recharging of the Tesla, the two hot legs are important. Is there an amperage output limit on your inverter?
I don't have an inverter. AFAIK, all US household solar inverters output split phase 240V, which you can then get 120V from, just like from a normal panel. I would guess most gasoline or fuel powered generators are like that too.
Only generators above a certain size output 240V. For example, in the Honda gasoline generator product line, only the ones that are rated 4,000W and above output 120/240V.
