Tesla Powerwall is now compatible with any solar inverter (but there’s a catch)

Tesla Powerwall 2 is compatible with all existing solar inverters. But there’s a catch.

Tesla Powerwall only continues to work in a blackout with a handful of inverters (around 5 of the better manufacturers such as Enphase and SMA), in what is known as island mode.

If you have single-phase power and you don’t have one of around 5 solar inverters that communicate directly with the Powerwall, there is a good chance your battery will discharge but then sit in idle during a blackout. In other words, it will not recharge from your solar system if there is a blackout and your whole system will be off until the grid comes back online. This obviously isn’t ideal given the increasing amount of blackouts we are experiencing across Australia.

If you have 3 phase power and a 3 phase solar inverter, the best option is to have an Enphase solar system. The Enphase system can remain on in a blackout with just the one Powerwall, and it will power 1 of the 3 phases in your home. When you place an order for your Powerwall battery, we will help you select the things in your home you want to keep on during a blackout and put these on the backup phase of your home. Typically this would include the fridge, freezer, some lights, the modem and a few power points. We don’t want to backup anything that uses too much power during a blackout such as air conditioners or pool pumps, so it takes a little bit of customisation to find the right solution for each of our customers.

If you have 3 phase power but don’t have an Enphase solar system, please contact us for more information. It can be possible in some cases to have 1 Powerwall connected to a 3 phase inverter, but in most cases, you will need 3 batteries for the system to work properly.

If you haven’t installed your solar system yet then an Enphase system is the best option in terms of compatibility with a Tesla Powerwall. If you already have solar, please contact us for personalised information on 1300 221 586 or request a callback here.

Comments

    • Solaray

      Hi Edi, as an Australian based installer we won’t be able to help. Please contact Tesla, I’m sure they would be happy to point you in the right direction.

    • Solaray

      Hi Claude, yes, the Powerwall 2 is compatible with an Enphase system. Give us a call on 1300 221 586 for more information on how the system works.

  1. Ramey

    Exploring the storage option, but will it be compatible with my Fronius Symo inverter. I am being persuaded to go with the hybrid, but ac coupled seems better for increased compatibility

    • Solaray

      Hi Ramey, an AC coupled solution means that there are no compatibility issues, it will work with any solar inverter. We’d love to go through some options with you, feel free to give us a call on 1300 221 586.

    • Solaray

      Yes, the Powerwall 2 is compatible with an Enphase system. Typically, you would need at least a 5kW solar system to generate enough excess solar power to charge the battery. Please request a callback for more information, we would be happy to help.
