Guidance for installer

Step1: Go to the local menu <About> via the inverter screen to see if the inverter has successfully recognised the inserted pocket Resister SN number.

Settings path: About → Inverter → Resister SN

If the "Register SN" on the inverter is same with the dongle, the connection between dongle and inverter is normal.

If “NA” is displayed, re-plug the dongle to ensure that the pocket Resister SN number is displayed properly on the screen.

Step2：Screw off two components at the bottom of Pocket 4G to take out the PCB.

Re-plug the SIM card to ensure the card has been correctly and firmly inserted. Make sure that the direction of the SIM card's missing corner is the same as the labeled direction.

After confirming that the SIM card is inserted, assemble the dongle and plug it back into the inverter.

Step3: Open the solaxcloud APP, then click “More” → “Local” → “Scan” in turn.

Scan the QR code on dongle then click ‘Login’ to local enter.

After successful entering in dongle, click the ‘Dongle’ at bottom, then click the gear in the upper right corner to enter the settings interface. Select 4G mode in the upper right corner and fill in the APN and Network deployment. (The flow of images is shown below in order from left to right)

Please ask your SIM card operator for the specific APN and network deployment and fill in data strictly as provided. Then click on Next after the selection is complete to configure the dongle.

After successfully completing the configuration, log back into your solaxcloud account to see if dongle is online.
