  If the 'Total [Wh]' value remains constant despite the site consuming power, verify that all connections at the inverter connectors and the meter are secure, focusing on the AC wiring at the meter's 10-pin connector. Also, confirm that the CT black and white cables are correctly connected to the 6-pin connector on the meter, ensuring the white CT wire connects to the L1/L2/L3 white dot and the black CT wire to the L1/L2/L3 black dot.

  If the Energy [in MWh] value displays a steady value even though the site is consuming power, check for loose connections at the inverter connectors and at the meter, specifically the AC wiring on the meter's AC wiring connector. Also, ensure the CT black and white cables are correctly connected to the CT connectors on the meter, and that the L1/L2/L3 cable passes through the CT in the correct direction, according to the arrow on the inside of the CT.
