The PV station generates power for self-consumption, but the electric equipment cannot
consume all the generated power. The inverter can monitor the on-grid electric data in real-time
and adjust the output power via a smart meter to avoid the residual current feeding back to the
utility grid.

6.5.1 Communication Network Introduction
Both the current sampling accuracy error margin of CT and the output voltage sampling
accuracy error margin of the inverter are ±1%, so the output power sampling accuracy error
margin of the inverter is ±2%.
