can my microinverters work without DTU Hoymiles?
DTU stands for Data Transfer Unit and is a data acquisition and transmission medium. Microinverters can operate without a DTU, but they cannot obtain module-level power generation data from PV arrays or perform online array diagnostics and maintenance. In other words, you won't be able to take full advantage of the module-level capabilities that microinverters are primarily designed for.
In addition, the Hoymiles DTU-Wlite-S is more than just a small device. This gives you free lifetime access to the Hoymiles S-Miles cloud monitoring platform. This means you always have all operating data at hand. View real-time, module-level data from your PV array, remotely diagnose problems, and maintain your system with minimal cost.
Can a DTU Hoymiles work and collect data without the internet?
Yes. Our Hoymiles DTUs have different models for different communication modes such as WiFi, Ethernet and 4G.
You can choose the 4G version if you have limited internet access. You can also check the system on the S-Miles Cloud platform by simply inserting a 4G card like a mobile phone.
How does the DTU Hoymiles communicate with the microinverters and the monitoring platform?
Our DTU collects data from microinverters using two communication methods: 2,4G and Sub-1G. DTUs are connected to the Internet via WiFi, Ethernet and 4G.
Is the DTU Hoymiles communication signal stable?
Yes, DTU Hoymiles are known for their reliable communication. To ensure stable data transfer, just make sure your home has a stable internet connection.
What distance between DTU Hoymiles and microinverters?
In an open area, the maximum distance between the DTU Hoymiles and the PV array is 150m, but in a real environment obstacles (especially concrete and metal) can significantly degrade the signal. In this case, we recommend using extended antennas so that the DTU signal is strong enough for data transmission.
Why is my DTU Hoymiles showing as offline?
If your DTU Hoymiles is not connected to the Hoymiles S-Miles Cloud, you can check three things.
1. First, make sure you have entered the WiFi password correctly in your DTU Hoymiles.
2. Next, check if your WiFi network is working.
3. And finally, the signal strength may be too weak. In this case, contact the installer.
Why isn't my monitoring working?
If your system is no longer reporting data, S-Miles Cloud can help you find the cause. After logging in, check if your system is listed as "offline".
If so, check if your DTU is connected to the internet (indicated by a blinking green LED). If the DTU appears to be online but still cannot connect to the 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 further assistance.
Can I transfer an investment to another installer's Hoymiles S-Miles Cloud account?
