Are you sure you need a solar production meter to test your system?
I just had my installer call me. He told me that the solar production meter needs to be in place for me to test my system and also to see my Tesla inverter turn on. I am guessing that some installers leave the wiring or the "continuity bar" in the production meter slot intact so that power will flow even without the meter. That is what enables some of us to "test" the system even without the production meter being there. But other installers leave the production meter slot open so that no power will flow through it without an actual meter being installed. In this case, we cannot "test" the system nor can we see the inverter turn on until the utility installs the Production meter and configures it to work. I am not sure how I feel about this because the utility could shut me off from my own solar production by simply turning off their Production meter!
