Growatt Shine3G / ShineGPRS Quick Installation Guide
Step-by-step guide to install the SIM card, wire the RS-232 connection, and register the Growatt Shine3G/ShineGPRS data logger in the ShinePhone app.
This quick guide walks you through setting up the Growatt Shine3G / ShineGPRS data logger: installing the SIM card, connecting it to the inverter, and adding it to your account in the ShinePhone app.

Step 1 — Install the SIM card
Remove the waterproof gasket, unscrew the screws, then open the shell and take out the PCB board, install the SIM card, put the PCB board back into its shell, tighten the screws and put on the waterproof gasket.

Note
- If there is already a SIM card in the data logger, skip this step.
- Don't touch other parts on the PCB board.
Step 2 — Electrical connection

A. If there is a DIP switch next to the RS-232 port, set DIP 1 to "ON". Then plug in the Shine3G/ShineGPRS and lock the screws.
B. If there is no DIP switch, poke out the small rubber plug from the screw hole adjacent to the RS-232 port. Plug into the RS-232 port and lock the screws.
