Can you add a Tesla Powerwall to an existing solar system?

You absolutely can add a Tesla Powerwall to an existing solar system! Read on to find out how.

Coupling a Tesla Powerwall to your existing solar system is incredibly useful if you find that you are exporting power to the grid each day from your current solar system. Instead of exporting your power to the grid, you could be storing the excess power generated from your solar system in your Powerwall, and only once your Powerwall is full, export any excess power to the grid which enables you to maximise your solar self-consumption dramatically.

This has the added benefit of not just helping reduce your carbon footprint, but also to reduce your energy bills by reducing your on-peak (most expensive) rate power by discharging the battery when the sun isn’t shining and you can’t get your free solar energy from the sun.

There are a few ways to add a Powerwall to an existing system:

  1. Add a Tesla Powerwall compatible inverter to your system. This solution is currently available, you’re even able to get TWO Powerwalls should your energy needs be high.
  2. Add a SMA Sunny Boy Storage unit to your current system and couple the Tesla Powerwall to it. This solution will be available around August 2016 and only able to be connected to a single Powerwall.
  3. Add an additional set of panels, inverter and Tesla Powerwall (or two!), with the new set of panels feeding power into the Powerwall first, and then any excess into your home, then out to the grid.

We are aiming to have an instant quote form for Retrofit customers organised by April, but, for the moment, if you head on over to the Tesla Powerwall quote form here, choose a 4kW system and ensure you choose ‘yes’ to the question ‘Do you already have a solar system?’ and you will be sent our current Retrofit offering in addition to a full new system.
