The perfect storm – self-sufficiency and sunny smiles

15 October 1987. A concerned Brit rings the BBC with reports there might be a hurricane on the way.

On the one o’ clock news, weatherman Michael Fish dismissed the idea, reassuring viewers that the worst of the storm would hit France and Spain. We all know what happened next: a cyclone so bad that 33 years later, we still remember the day the weatherman got it wrong.

Thankfully, our ability to predict and deal with the effects of extreme weather has improved since then. This includes power outages. I’ve written before about how home batteries can be used to store solar power ‘in reserve’ for emergencies. Today, the Tesla Powerwall 2.0 goes one step further, automatically protecting homeowners from storm-induced power outages. That means extra peace of mind for homeowners, even when the weatherman does get it wrong.


Tesla Powerwall’s automatic Storm Watch function

With a 13.5kWh capacity, the Tesla Powerwall 2.0 meets the needs of even the most power-hungry household, storing excess solar energy to help homeowners go ‘off-grid’ as often as possible.
To do this, the Powerwall automatically uses a range of technologies to optimise its own performance – including before and during severe weather. Using its Storm Watch function, the Powerwall communicates with the National Weather Service to detect when storms are on the horizon. When this happens, the battery charges itself to maximum capacity, providing backup power when the bad weather hits.

All of this can be monitored via the Tesla smartphone app. So far, so reassuring. But how does Storm Watch work in practice?
