Charging from grid at night

Charging from grid at night

Ian.Mew | 16 marts 2019

It’s winter here in the UK and using Octopus Energy as my supplier, I’m able to take advantage of half hourly variations in electricity prices.

We don’t have enough sunshine to either power our house or charge the batteries at this time of year, so setting ‘peak’ & ‘cheap’ electricity periods on the iPhone App used to allow me to charge my Power Wall 2 to 100% during the night and then power my house using the stored cheap electricity during the day when energy prices are higher.

Over the past month, this has stopped working, with the Power Wall only charging to about 30% at night, thus requiring energy to be drawn from the grid during expensive times.

I’ve emailed Tesla support with images, but no reply. Can anyone help me to fully charge my batteries at night please?

Thank-you!

In order for me to charge my Powerwalls from the utility company is to set the Tesla app "Storm Watch" to on. Then there has to be a notice from the National Weather Service of a storm in my area (US, Colo.). Your system may be different.
