4G logger setup

Use a 4G logger where the customer’s Wi-Fi is weak, absent, or unreliable (rural sites, sheds, new builds before NBN). It’s essentially plug-and-play.

Steps

1. With the inverter off, screw the 4G logger into the inverter’s COM / logger port and hand-tighten the collar.
2. Confirm the SIM is seated (most units ship with the SIM pre-installed and data pre-activated — check the supplier note).
3. Power up the inverter and watch the logger LED:
   • Solid/steady = connected to the network and cloud.
   • Blinking / off = still acquiring signal, or no coverage at that location.
4. In DeyeCloud, add the logger to the plant by its SN (same as a Wi-Fi logger).

Tips

• Mount for signal: avoid metal switchboards/enclosures that shield the antenna. Relocating the logger 20–30 cm can be the difference between 1 and 4 bars.
• If it never connects, confirm coverage for the SIM’s carrier at that address and that the data plan is active.

Wi-Fi available instead? Use the Wi-Fi logger guide.
