My 5kw solar system with Powerwall 2 was installed last week. Doing some tests I noticed on the Tesla app that the house power consumption shows higher in Self-Powered mode (6kw +) than in backup mode (less than 3kw) with just the refrigerator and the internet router running. In Self-Powered mode, the graph shows up and down in the house power consumption during the day contrary to Backup mode which shows a constant graph. The same happens to the Powerwall which charges and discharges even if the solar panels supply all power needed for the house. Any ideas why this is happening?
