About Voltage Taps and Current Transformer Connections
The Tesla Remote Meter functions by measuring voltage (by voltage tap) and current (by Current Transformer, or CT) at key locations in the system. For the meter to function correctly, the following are critical:
- The Tesla Remote
Meter
voltage line harness leads must be connected to the correct
phases.NoteRegardless of the grid type the system is connected to, Tesla Remote Meter must always be connected to L1 and N. If the meter is connected to L2 and/or L3, but not L1, it will not be powered.
- The CTs must be
placed around conductors of the correct phase:
- CT1 = L1
- CT2 = L2
- CT3 = L2
Note
A single Tesla
200 A CT or 800 A CT can be placed around multiple conductors which
are on the same phase, provided the sum of the conductor’s current
ratings does not exceed the CT's maximum current capacity. This is
especially useful for systems with multiple solar inverters.
Install the Tesla Remote Meter and CTs describes how to perform these steps correctly, but the following diagrams illustrate some high level correct and incorrect meter / CT installations.
