You said it is a new system, do you have PTO? What mode do you have the system set to?

Without the backup switch the system is unable to monitor what is coming or going to/from the grid. Pairing the phone to the Powerwall is more for when power is off and you have no communication with Tesla mother ship you can see how much battery and solar you have so you can manage your loads...

There are plenty of people who have a mixed system here and it works fine as long as it is done properly. I'm not familiar with Solar Edge but I believe it should be able to operate while your system is off grid as long as your batteries are less than 95% the batteries should put out a healthy...

Do you have the gateway with your current system? You will need CT's on the Enphase part connected to your existing system so the Powerwalls know that energy is there and how to handle it on and off grid.

I can not think of a legal and safe way to hook a small wire to a 100 or 200 amp line that I would want at my house and that would only be useful if you do not have the backup switch unlike the other person you are referring to.

No electrician should hook a meter like you want to the line side of your meter. If someone did and your power company saw it they would not be very happy about it.

The Emporia must have power for it to work but it still works if the Powerwalls are supplying the power to it. The same goes for your volt meters and unless they are strategically placed where the line from the grid can be monitored and that part of the line loses power when the grid goes down...

I agree with Matt but I like the Vue for the information you get in the app although it does not give you voltage readings it shows the wattage/current used.

I don't see how the item you linked to would be of any use they go between a battery and a load to take readings. The Powerwalls connect through AC and at least 30 amps.

For the Powerwall's feed I would call it bidirectional. I just wanted to point out that on the Vue CT's only the Mains are capable of reading bidirectional and the smaller CT's only read in one direction. I wanted to monitor each of my Powerwalls but I didn't think it was worth having a...

I don't know but hopefully this https://www.tesla.com/support/energy/solar-panels/after-installation/troubleshooting-your-system can be helpful as you wait for Tesla. I have not gone through the troubleshooting steps but I have read up on the backup switch on their site.

It also depends on the equipment being installed and your power company. For Tesla to install the backup switch on my meter socket my power company TEP required a line disconnect and would not reconnect power without the county approval.

Thank you I think I had frequency on my brain!

Correct on the curtailment I meant 98% and 97%. The graphic is from Emporia Energy monitor it is a CT around one leg of the Enphase combiner feeding in to my generation panel.

My Enphase profile looks like it should do well for me if I ever need it. In the pic below I went off grid and once the Powerwall hit 98% it started increasing the frequency and the Enphase was completely off by 62Hz then I started charging the car at 24A and the frequency was lowered to 60Hz...
