Your Tesla Powerwall system is a rechargeable home battery designed to maximise your homes energy independence, that means

• you can have backup power in the event of a power cut to keep your home running 
• you can power your home in an evening from electricity generated during the day from your solar pv system
• you can set time based control which maximises savings by optimising how your Powerwall provides power to your home. 
• you will lower your carbon footprint for you home 
• cheaper electricity bills.

The Powerwall is an intelligent system that can be customised to your energy needs and has the ability to charge from solar and from the grid. 

You have various setting options and with Time-Based Control, your Tesla Powerwall will charge from and discharge to the grid at certain times to take advantage of changes to your energy supplier tariffs, such as Octopus Agile, that occur throughout the day and season - but how do you set this up ?

By using the Net Zero for Tesla app which you can find here you can integrate your Octopus Agile tariff into your system and make full use of all you low cost or even negative tariff rates without any fuss - this allows your Tesla Powerwall system to make the best use of energy throughout each and every day
