Hi All Looking to install a PW2 with a new PV system. Are current usage is only about 12 - 18kWh a day but it will double when we get an EV. Most of our usage is at night. I am wondering what size PV system do I need to charge 1 PW2 during the day so that I can use that power at night to charge the EV? Also, my Tesla sales rep told me that they have Powerwalls back in stock and there are no more delays. I'm not sure If I believe him. Can anyone confirm if this is true? I am trying to get the PV system with a PW installed by before the end of the year. Thanks.
