Ok here s my experience that hopefully will answer your question.
Connect powerwall to your own solar panels.
The retrofit tesla powerwall battery doesn t have to communicate with or connect to the existing solar pv system at all.
When additional power is required within the home the home can pull from the utility grid.
Use solar energy to power your home and reduce your dependence on the grid.
During the tesla powerwall solar installation our installers will connect your current solar pv system to the powerwall s.
Powerwall gives you the most for your money with great specifications three different operating modes and reliable energy all for 11 000.
We ll determine how many solar panels and powerwalls are right for your home based on your energy needs and goals for emergency power.
All you have to do is install your solar panels and start saving.
Again this isn t the perfect answer for everyone or a one size fit all product.
So depending on what you re looking for from an energy storage system a tesla powerwall could be worth it for your home.
And yes you ll need lots of solar panels to charge it but you ll also need 100 reliability and true fault tolerance with your solar system that is no single points of failure which can bring the entire solution down.
The two powerwalls total 30kw worth of storage.
The meter installs in the switchboard and measures the real time rate of energy flow i e.
Central string inverters verses microinverters now has a whole new meaning.
The power either to or from the grid.
The dc power then travels to the inverter and changes into ac power.
Firstly i have a 6kw solar system and recently added two powerwall 2 s to work as battery backups.
They are two completely separate systems.
Powerwall is charged by solar during the day when solar panels are producing more electricity than the home is consuming.

I still need to be tied into the electrical grid because the powerwalls cannot take the excess electricity my solar system generates.
The average size solar system we sell with a powerwall is a 6kw system or about 20 solar panels.
When the sun rises solar begins powering the home.
After installation your solar panel grid will generate dc power as normal.
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 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.
Yes pw2 is huge.
