Hoymiles HMS-400W-1T Micro Inverters Questions & Answers
For what application was the Hoymiles HMS-400W-1T developed?
The HMS-400W-1T microinverter was specially designed for mini-PV systems such as balcony power plants and is ideal for decentralized energy supply in the private sector.
Which PV modules is the inverter compatible with?
It supports PV modules with an output of 320 to over 540 watts and covers a wide range of commercially available modules thanks to its wide DC input voltage range of 16–60 V.
At what voltage does the HMS-400W-1T start operating?
Thanks to the low starting voltage of only 22 V, the device can start converting energy early, thus maximizing the daily yield.
How efficient is the device in operation?
Thanks to its precise MPPT control, the HMS-400W-1T achieves a peak efficiency of up to 96,7%, ensuring high energy yield even under changing environmental conditions.
How is the system monitored?
The integrated WiFi module enables wireless real-time monitoring either via direct connection or via the cloud-based S-Miles Cloud platform – without the need for an additional gateway.
Which security-relevant functions are integrated?
The inverter features a quick shutdown function and galvanic isolation through an isolated transformer, ensuring a high level of electrical safety.
How is the microinverter installed?
Thanks to its plug-and-play design, the device can be easily and quickly installed directly under the PV module or on the mounting system – ideal for DIY projects and flexible installations.
Is the device suitable for outdoor use?
Yes, the housing meets protection class IP67 and is designed for permanent outdoor use. Operation is possible even at ambient temperatures of up to +65°C.
