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!
