I know that generally solar panels are turned off when there is a power outage due to the need preventing electrocuting utility workers. However, with the Tesla PW2 installed, we are cut off from main and the solar panels are still operational feeding into the PW2; and of course, we can use power stored in the PW2 as backup during the power outage.
Today, we have experienced a planned power outage and tried this the first time: ON the day prior we switched to "Backup Only" mode 100%. The grid turned off and the PW2 jumped on perfectly—we did not even notice.
HOWEVER, the solar panels first did not feed any energy into the house or the draining PW2 according to the app. After about 30 min they kicked in and started feeding into the PW2 and the house.
Note: There was plenty of sunshine (as usual in Sydney I might add)!
Any reason for this delay?
