DTU, short for Data Transfer Unit, is a medium of data collection and transmission. Microinverters can certainly work without DTU, but you will not be able to get the module-level power production data of your PV system, nor can you perform diagnosis and maintenance of your system online. In other words, you will not be able to tap the full module-level capabilities for which microinverters are built in the first place.
Furthermore, buying a DTU is more than buying a small gadget. It gives you free access to our monitoring platform S-Miles Cloud for life. You will have all the operation data at your fingertips. You can check on the module-level data of your PV system in real-time, diagnose any problems remotely, and maintain your system at minimal costs.
Yes. Our DTU comes with various models for different communication modes including Wi-Fi, Ethernet, and 4G. You can choose the 4G version when internet access is limited. Just insert a 4G card as you do for your mobile phone and you will also be able to check on your system on the S-Miles Cloud Platform.
To help you find the right fit for every location, you can connect via Wi-Fi, GPRS or LAN depending on your specific products.
Yes, our DTUs are known for their reliable communication. You just have to make sure that there is a stable internet connection in your home to realize robust data transmission.
If your system has stopped reporting data, S-Miles Cloud can help you uncover the root cause. After logging in, check whether your station is listed as ‘offline’. If so, check your DTU is connected to the internet (indicated by a flashing green LED). If the DTU seems to be online but still isn’t connecting with S-Miles Cloud, check that you have entered the correct serial number.
If these steps don’t help, speak to your local installer or contact us for more help.
If your DTU is not connected to S-Miles Cloud, there are three things to check. First, make sure you have correctly entered your Wi-Fi password in the DTU. Second, check that the Wi-Fi network is operational. Finally, your signal strength may be weak. If so, contact your installer.
