FAQs
What defines HMS photovoltaik technology?
HMS photovoltaik technology generally refers to the high-performance microinverter series (like the HMS-800 or HMS-2000) manufactured by companies like Hoymiles. It is characterized by Sub-1GHz wireless communication, module-level MPPT tracking, and a 4-in-1 or 2-in-1 design structure that connects multiple panels to a single microinverter unit.
Can I install an HMS microinverter myself?
Yes, for smaller systems like balcony power plants (up to 600W or 800W depending on local regulations), hms photovoltaik systems are designed for DIY installation. They utilize Plug-and-Play connectors. However, for larger roof-top systems involving complex wiring and mains integration, a certified electrician is legally required and recommended for safety.
How does the HMS series differ from the HM series?
The primary difference lies in communication and cabling. The older HM series uses 2.4GHz communication and a daisy-chain cable method. The newer hms photovoltaik series uses Sub-1GHz communication (which is more stable through walls) and a “Flex” trunk cable system that allows for more flexible installation layouts.
Is the HMS-800W compatible with all solar panels?
The HMS-800W is highly compatible but not universal. It is designed for 60-cell, 72-cell, 120-cell, and 144-cell PV modules. You must check that the panel’s Open Circuit Voltage (Voc) and Short Circuit Current (Isc) do not exceed the microinverter’s maximum input ratings. It is optimized for modern high-power panels (400W-550W).
What happens if one panel is shaded in an HMS system?
This is the main advantage of hms photovoltaik setups. Because each panel has its own MPPT (Maximum Power Point Tracker), shade on one module only affects that specific module. The rest of the system continues to generate power at 100% capacity, unlike string inverters where one shaded panel acts as a bottleneck for the whole string.
How do I monitor my HMS photovoltaik production?
Monitoring requires a DTU (Data Transfer Unit), such as the DTU-Pro-S or DTU-Lite-S. This device communicates wirelessly with the inverter and sends data to the S-Miles Cloud platform. You can then view real-time power, voltage, and historical energy generation via a smartphone app or web browser.
Are HMS inverters waterproof?
Yes, hms photovoltaik inverters are typically rated IP67. This means they are completely protected against dust ingress and can withstand immersion in water up to 1 meter depth for 30 minutes. They are designed to be mounted outdoors, usually behind the solar panels, and can endure rain, snow, and extreme temperatures.
