This document introduces the export limitation function of Growatt 3000-15000TL3-S inverter, including meter selection, meter connection and communication and configuration.
The document provides instructions on selecting and connecting the approved Growatt SPM (single-phase) or TPM (three-phase) meters to enable export limitation. It details the physical connection via RS485 ports between the meter and the inverter.
Configuration methods are described for enabling zero export or setting a specific power limit. Users can configure these settings through ShineServer, ShineBus/Modbus Test software on a laptop, or directly via the inverter's LCD interface using specific knock sequences.
Only Growatt meters are approved; use Growatt SPM for 1-phase systems and Growatt TPM for 3-phase systems.
Connect the meter RS485 port to the inverter RS485 connector. The input side connects to the grid side and the output connects to the home load side.
Go to the Meter Info page, double knock to enter the enable/disable page, and fast knock 3 times to confirm enabling it.
