How can a 60KTL-M0 or a 100KTL-M1 be operated with a 4G dongle?

To do this, the inverter must first be accessed using the FusionSolar app and a USB commissioning stick. After successfully logging in with the "extended user", the required APN data of the Internet provider can be entered in the main menu under:

Settings -> Communication Configuration -> 4G Communication

Now the commissioning stick can be exchanged with the 4G dongle.

Attention:

It is essential to remove the SIM PIN lock beforehand.
