Q9: I have connected my inverter and data logger successfully and powered them on, but only the POWER & RS485 LEDs are on, while the LEDs STATUS& LINK are still dark? Why is that? Have I connected them successfully?

If you have completed the connection between data logger and the inverter by following our Quick Guide, and the POWER and RS485 LEDs are on, congratulations, you have successfully connected the data logger to the inverter. While, in such case, the STATUS and LINK LEDs are still off, it means that you haven’t set the network of the data logger or the setting is not successful. Please continue to set the network of the data logger, and detailed procedures are available on our Quick Guide.

Please wait for 3 to 5 minutes after you completing the network setting. Till then, if the LINK LED is on, the network setting is successful.

When the LED RS485 flickers, it means the device is transmitting data to the portal; while it is lightening, the data logger is under normal operation. Our device transmits data to the monitoring portal every 5 minute, and during that the LED will be in flickering. Please wait for a while patiently.

Q12: The network setting is successful, but I still cannot receive any data, why is that?

In this case, there may be three main reasons. First, the data logger transmits data to the portal every 5 minute, please wait for a while patiently; second, the device may not connect to our server successfully, please check your network setting and reset it if necessary; third, please check the weather condition, if it is cloudy or dark outside, the inverter may not work, and in such case, there won’t be any data on the website.

Q13: Why can’t I find any historical data of my inverter in history interface?

The portal can only show data that are collected after activation of user’s account. That is to say, data collected before registration cannot be seen on the portal; however, it is saved on the database of the device. Please register on the portal right after you completing the setting procedures of the device, so that full data can be obtained on the portal.

Data on the portal updates every 5 minutes, and the history data will be preserved and displayed on the ‘History” interface automatically. If there is no data shown on the portal after registration, please check the network status of the server.
