Additional Tesla Powerwall

StevieGal

Hi,
I am considering adding an additional Powerwall to my existing Solar + Powerwall. Can anyone confirm how an extra Powerwall works regarding discharge, do they discharge equally together or when 1 is empty 2 discharges? Also can I configure Powerwall number 2 to just charge from Solar rather than overnight cheap rates which Powerwall number 1 does at present.

From a control point of view you are just going to be dealing with one larger battery, you will have no ability to set them to do different things.

When discharging the energy comes from both batteries at the same time, but probably a little more from the newer one as it will have a little more capacity, so it keeps them balanced on a percentage remaining basis.

A Rogue Tesla Powerwall 2.....

I got a Powerwall 2 in Nov 23 and i'm both pleased and displeased with it in equal measure. ( now June 24 )

The installer isn't that responsive on issues such as "the Powerwall 2 won't charge after a power outage" which the Powerwall should have taken care of seamlessly but didn't. 

6 days have gone past and they have not come back to me with a fix.

Also what as a user you cant do, is contact Tesla for support - There as far as I can see is only support for the installers.

so what happens in Nov 24 when its out of warranty ? What do I do then ?

Although a generally good system, when it fails you can't re-boot it via the app or fault find as it just refuses to play.

The app too is bonkers sometimes, as it randomly decides to send power to the grid rather than the battery. 

I have solar edge inverters on two separate systems and they work 100% faultlessly since 2014 - Brilliant customer support too.

Tesla - From my experience isn't all its cracked up to be and to be honest I'm very disappointed to say this.
