Each Powerwall can provide up to 5 kW of continuous power. You can back up any number of appliances, so long as their combined power usage does not exceed the total power rating of your Powerwalls. If, at any point, the backed-up load exceed this 5 kW limit, the Powerwall will shut off to protect itself.
Starting some loads with high inrush current during a power outage, like air conditioners and motors, may overload Powerwall and cause it to stop providing power to your home. If this occurs, turn off these loads, and Powerwall will attempt to restart within a minute. Otherwise, consider manually restarting Powerwall, as described below.
If your Powerwall system stops producing power, it may be in a standby state after running low on energy or after repeated overloads. To restart your system, switch off any energy-intensive loads to reduce the amount of power needed. You can initiate a restart with a quick toggle of the on/off switch on any Powerwall in your system. Remember that in order to maintain a connection to the Gateway, you must leave the Powerwall switch in the ON position (the “1” depressed on the on/off switch).
A restart consumes some of Powerwall’s remaining stored energy. If energy is low and there is insufficient solar to charge, Powerwall will return to a standby state after 6 minutes, so it is best to initiate a restart during daylight hours.
