6.5.1 Communication Network Introduction

Power Limit Network
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.
