Why the smart meter matters
For most SEMS deployments, the smart meter is the reference point for:
- grid import;
- grid export;
- site-level direction checks;
- several higher-level control and alarm decisions.
If the meter direction is wrong, many downstream conclusions will also be wrong.
Before you begin
- the meter installation point is defined for the project;
- the device appears in the public Supported Devices list;
- the correct transport and profile are known;
- slave ID or TCP settings have been confirmed on the device side.
Commissioning procedure
- Add the meter on the Devices page.
- Confirm the correct device profile and communication method.
- Save the device and verify that polling succeeds.
- Open the live dashboard or device view and inspect current import/export values.
- Compare the SEMS reading with the physical site condition.
Import/export direction check
At a minimum, verify:
- importing from the grid is displayed as grid import;
- exporting to the grid is displayed as grid export;
- zero or near-zero transfer behaves plausibly.
If the sign convention is wrong, stop and correct the configuration before continuing with inverter or battery control validation.
Common causes of incorrect direction
- CT orientation or meter-side direction configuration
- wrong device profile
- wrong phase/order interpretation
- using a meter position that does not represent the site PCC
Public support boundary
Only device families with reviewed public support status should be described as customer-facing supported. Do not assume that every implemented meter profile has already been verified on physical hardware.
