The Tesla Powerwall 2 comes with its own Battery Inverter included. This means it is compatible with any existing solar system. So, yes, it will work with your existing solar system no matter what type you have.
Having said that, in practice you will still need permission to add it to the grid from your local network. This can be a problem if your current solar inverter is bigger than 5kW.
