Due to this household's efficient consumption, our design solution specified 4kW of solar PV, a single Tesla Powerwall home battery, and a Lumin Smart Panel. Typically Tesla requires two Powerwalls in order to backup an entire home. The Lumin Smart Panel enables some homes to get sufficient backup without needing a second Powerwall by automatically shedding the largest circuits in the home in the event of an outage. This ensures that major appliances don't ask the Powerwall for more power than it can handle all at once and also lengthens the duration that the Powerwall can backup the home. Through the Lumin Smart app the homeowner can monitor the power consumption of their entire home in real time as well as consumption from up to 12 individual circuits. Additionally they can reenable large circuits such as the range individually while ensuring the battery isn't overloaded with demand. You can even use the Lumin app to identify vampire drain (small amounts of power consumption when a device or appliance is not in use that add up over time) and set a schedule to turn off that circuit such as in the middle of the night or when you are traveling.
