There can be 2 problems with the Smartmeter:
- Smartmeter installed in the wrong place:
Check on your monitoring space the consumption curve. If you see that you have no consumption at night and that during the day the consumption is very similar to the production of the PV fields (as in the example below) it is very likely that your Smart Meter is not installed in the right place. Check this by clicking on the following link: Verification of Smartmeter positioning.
- Smartmeter not correctly wired:
To check the correct communication between the inverter and the Smartmeter please follow the procedure described in the following link: Diagnosis Communication problem
