Ok here s my experience that hopefully will answer your question.
Connect powerwall to your own solar panels.
Powerwall is charged by solar during the day when solar panels are producing more electricity than the home is consuming.
All you have to do is install your solar panels and start saving.
Harness the power of the sun at all hours of the day with the tesla powerwall.
Yes pw2 is huge.
The two powerwalls total 30kw worth of storage.
Use solar energy to power your home and reduce your dependence on the grid.

Central string inverters verses microinverters now has a whole new meaning.
In this situation a battery is.
Purchase solar at the lowest price of any national provider with tesla s price match guarantee and take control of your monthly electricity bill.
The power either to or from the grid.
When additional power is required within the home the home can pull from the utility grid.
During the tesla powerwall solar installation our installers will connect your current solar pv system to the powerwall s.
We ll determine how many solar panels and powerwalls are right for your home based on your energy needs and goals for emergency power.
After installation your solar panel grid will generate dc power as normal.
The average size solar system we sell with a powerwall is a 6kw system or about 20 solar panels.
The retrofit tesla powerwall battery doesn t have to communicate with or connect to the existing solar pv system at all.
Firstly i have a 6kw solar system and recently added two powerwall 2 s to work as battery backups.
Again this isn t the perfect answer for everyone or a one size fit all product.
If you have a storage ready solar system you already have an inverter that can easily integrate a battery into your solar panel system.
So depending on what you re looking for from an energy storage system a tesla powerwall could be worth it for your home.
The dc power then travels to the inverter and changes into ac power.
Powerwall gives you the most for your money with great specifications three different operating modes and reliable energy all for 11 000.
They are two completely separate systems.
The level of difficulty associated with adding a battery depends on whether your solar panel system was designed with the intention of adding energy storage later on.
I still need to be tied into the electrical grid because the powerwalls cannot take the excess electricity my solar system generates.
