You only have to perform this step if the SunPac LiOn is not connected to a Suntrol eManager.
In order to register, the serial number of the SunPac LiOn has to be entered into the portal. The SunPac LiOn can measure the output and power consumption via its integrated data logger and display the data in the portal. The inverters or an additional Solarlog data logger do not have to be registered on the Suntrol portal in this case.
