I’ve been advised that there will be a scheduled grid outage for up to 8 hours (during the day) in my area and so I want to have my PW2 fully charged before it starts. The forecast in Sydney is pretty ordinary this week so I can’t rely on it being sunny to power my house.
So what’s the best way to prep for this? One option is to use TBC mode to ensure the battery is charged to 100% from the grid before the peak period starts (2pm) on the day prior to the outage, then switch the Powerwall off using the little switch on the side to preserve the power, then turn it back on again in the morning before the outage starts. But is that what the little switch does?
Another option is to use TBC mode to get the battery charged to 100% by 2pm the previous day, then set the “reserve for power outages” level in the App to 100% so that I’ll be on grid power until the grid outage and then the PW will take over automatically.
Thoughts?
