Taking Tesla Powerwall Off-Grid

George Riley · 20 Jan 2022

Powerwall has been around for almost six years now, and one of the reasons we like it is that Tesla is always innovating and improving the product. Often, this comes in the form of over-the-air updates to the battery’s software.

The latest feature is the ability to take your Tesla Powerwall off-grid and supply your home as if there were an outage. This has launched alongside the news that Powerwall is now suitable for off-grid installations. Read on to find out more about both…

Are Solar Batteries Worth It in 2021?

George Riley · 07 Jul 2021

Good Energy estimates that the UK will need 23-55 GWh of domestic storage to reach net zero, which is equivalent to 1.5-4 million Tesla Powerwall sized batteries in people’s houses. Why? Because battery storage in homes is vital to help people use more renewable energy, reduce the evening peak demand and avoid costly transmission upgrades to the national grid.

Solar PV Monitoring Solutions: The Best Apps and Platforms

George Riley · 01 Apr 2021

Since solar panels are static, there’s little to actually, well, see when they’re generating. Sure, it’s nice to start receiving smaller energy bills but, if you’re like most of our customers, you’ll want to dig into the performance data every now and then.

As well as checking when the most solar power is being generated (a useful reminder to turn on the dishwasher and make the most of that free electricity), solar monitoring is great for reviewing past output and comparing performance. Sudden drops can indicate faults that need fixing, or help assess if it’s worth giving the panels a clean.

Wondering which solar PV monitoring solutions are the best? Read on...

Tesla Energy Plan for Solar PV and Powerwall

George Riley · 05 Nov 2020

We’re entering a period of dramatic change for the energy sector. From smaller independents breaking the hold of the Big 6 and consumers generating their own solar power to dynamic pricing plans and smart homes.

The latest innovation is one that combines all of these: Octopus’s Tesla Energy Plan. Previously this was only available to Tesla vehicle owners, but now it’s open to everyone with solar PV and Powerwall battery storage.

Upgrading Your Home Battery to Backup

Mark Golding · 25 Mar 2020

In light of the recent news, the idea of being grid independent with your own power cut protection has become a lot more attractive. 

We have had a number of customers interested in upgrading their solar PV or battery systems to protect them from power cuts. As we mentioned in a previous blog, a solar PV system alone will not protect you from an outage. With no batteries, if the power goes out, your PV system will switch off. This is a safety mechanism so that you do not discharge any excess PV energy to the grid and seriously injure someone if they are working to repair the grid near your house!

Even if you have a battery, some of them will not be able to island your property from the grid, which is the crucial step needed to have a backup system. Batteries need to follow strict DNO regulations to operate during a power outage as well, and will always need prior grid permission before installing.

Do You Need Power Cut Protection?

George Riley · 11 Feb 2020

At the end of January, thousands of homes local to us across Reading, Bracknell and Basingstoke suffered power outages for an average of 3 hours. This past week, Storm Ciara denied over 500,000 of us access to electricity. And last August the country was hit by the worst blackout in a decade, affecting hospitals, trains and over a million people.

Victor Kiam and the Tesla Powerwall: So Impressed I Bought the Company

Erica Charles · 12 Apr 2019

Yesterday I had my own modest version of a Victor Kiam moment.

If you are too young to remember Mr Kiam, spend 30 seconds watching this… Mr Kiam's famous line ‘I loved the shaver so much I bought the company’ was the cornerstone of a hugely successful 1979 advertising campaign.

Mr Kiam was swept away by the joy of a sharp shave. For me it was Tesla and the sheer passion with which they are pursuing their mission ‘to accelerate the world’s transition to sustainable energy’.
