Power Cut? Not My Problem... Tesla Powerwall's Solar Panel Backup

Erica Charles · 01 Mar 2019

The long-awaited Powerwall 2 backup capability is ‘on the water’, with the first wave of deliveries expected in April.  There’s a two stage roll-out, based on the type of earthing system required. Stage 2 will be in August.

If you are familiar with the Powerwall system, you will know that the system consists of the Powerwall unit itself, which houses the battery and the inverter, along with a ‘gateway’ which provides remote connectivity.

The original gateway, ‘GW 1’, was a plastic fronted box providing remote connectivity to the system.

From April this will be upgraded to a new gateway, GW 2, a stylish frosted glass-fronted ‘mini’ version of Powerwall 2, measuring 380mm wide x 580mm tall x 127mm deep, and weighing 9.8kg.  It is IP55 rated, so suitable for outdoors, and can be padlocked to stop any unwanted access.

The main purpose of the gateway upgrade is to enable ‘backup’ capability so that the homeowner can still power their home in a power cut.

So confident is Tesla that all customers will want the new backup enabled system, that they are actually expecting to discontinue GW 1 altogether, even though GW 1 offers a lower cost entry point into the Powerwall 2 system.

Tesla has certainly done its research. According to the company, in the nine month period 18/6/18 – 18/2/19 there were 93,965 unique power cut incidents in the UK, typically lasting between 15 mins and 4 hours and impacting 2 million customers. Anyone with a solar panel backup system in place would be smiling now....

[Apparently there are 22,200  online searches for "Schadenfreude" every month in the UK.  I wonder if Mr Musk has checked that stat out ....]
