Tesla Powerwall sets itself apart from other battery storage companies by continuously updating the software of customers’ products remotely to include entirely new features instead of forcing consumers to buy a new version with upgraded features.
Tesla Software Updates
Powerwall customers, rejoice. Tesla just released a software update for Powerwall 2 which adds a mode called Storm Watch. Customers in certain (unannounced) regions will notice this added feature on their Tesla app. With Storm Watch enabled, Powerwall 2 will continuously check weather forecasts. When Powerwall 2 sees a storm coming, it will automatically switch modes to “Backup Only” and will be exclusively discharged in the event of a power outage.
Automatic Power Outage Protection
Powerwall has always given users the ability to protect their homes against power outages. The “Backup Only” mode is not the setting most customers use on a daily basis. Instead, they are using modes which store their solar production to be used at night or to store energy from the grid to use during peak pricing. Users would then have to manually switch the mode to save power before an approaching storm. This cumbersome process can be the difference between a charged Powerwall and customers left in the dark during a storm. Storm Watch aims to fix that, just in time for peak hurricane season.
One neighborhood in Puerto Rico is experiencing first hand the benefits that a solar system paired with Powerwall can provide. Following the destruction of Hurricane Maria last summer, many communities on the island are still without reliable power. Except for Israel Melendez, Jr. Israel Melendez Jr. had previously installed a 12kW solar system and 3 Tesla Powerwalls that kept his house functioning completely off the grid following the hurricane. He was even producing double the amount of energy he needed to keep his home fully functioning. This excess energy was then transferred back to the grid for his neighbors to utilize.
