Q:Can my microinverters work without a DTU?A:
DTU, short for Data Transfer Unit, is a gateway 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.
-
Q:Can DTU still work and collect data without no Wi-Fi coverage?A:
Yes. Our DTU comes with various models for different communication modes including Wi-Fi, Ethernet,or 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.
-
Q:How does DTU communicate with microinverters and the monitoring platform?A:
Our DTUs will collect data from microinverters via two communication methods: 2.4G or Sub 1G. DTUs are connected to the internet via Wi-Fi, Ethernet, or 4G.
-
Q:Is DTU's communication signal stable?A:
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.
-
Q:How many microinverters can a DTU monitor?A:
In optimal conditions, one DTU can monitor up to 99 PV panels. In open space, the maximum distance between DTU and your PV system can be 200m. However, in real settings, obstacles (especially concrete and metal) can cause significant signal attenuation. In this case, extended antenna is recommended to make sure that your DTU signal is strong enough to transmit data.
-
Q:Why does my DTU show as offline?A:
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.
-
Q:Shall I pay for accessing the monitoring platform?A:
Access to the Hoymiles monitoring platform is generally free for basic usage. However, if you require additional services such as APl access, there may be associated costs depending on the plan type you choose. For specific details regarding any charges, it is best to contact Hoymiles sales or support for clarification based on your needs.
