From the spec it shows that the PowerWall 2 supports the following modes: Solar self-consumption Time of use load shifting Backup Off grid I am hoping that the powerwall can do a combination of the above at the same time. I would like my powerwalls to charge to 70% overnight for "Time of use load shifting" then during the day I would like them to use that stored energy and do "Solar self-consumption". When I get a powercut I would like it to operate in "Backup" mode. Does anyone have any information if this is the way it works or are the modes exclusive? I ordered 2 powerwalls but might have to cancel if it can not do the modes in parallel.
