How to check whether the CT or meter installation is correct or not from inverter LCD?

1. Is there an error on the inverter (Refer to Troubleshooting Guide if so)
2. Set the inverter to OFF mode
3. Turn ON some house loads
4. Check the Pgrid value (Press DOWN button on the main screen)
If positive, then the meter/CT direction is reversed.
If negative, then the meter/CT direction is correct.
