Hoymiles HMS-1600-4T Micro-inverter: 4-in-1 power for large-scale installations


The Hoymiles HMS-1600-4T micro-inverter stands out as one of the most high-performance options on the market for demanding residential or commercial photovoltaic installations. Designed to manage up to four solar panels simultaneously, this high-end model delivers a nominal output power of 1600 VA. Thanks to its innovative architecture, it significantly reduces installation time whilst lowering the overall cost of your system compared to using several conventional micro-inverters.

Equipped with Sub-1G wireless communication technology, the HMS-1600-4T guarantees unrivalled data transmission stability with the Hoymiles DTU gateway, even in industrial environments or through complex structural obstacles. With its exceptional MPPT efficiency of 99.80% and a maximum efficiency of 96.70%, it eliminates energy losses to maximise the return on investment of your energy transition.






Individual optimisation and maximum security

Unlike central inverters, this micro-inverter features 4 fully independent MPPT trackers (one per panel). This means that if one of your modules is partially shaded, dirty or underperforming, the other three continue to produce at their full potential. In terms of safety, the unit features a galvanically isolated high-frequency transformer and a rapid shutdown system compliant with industry standards, ensuring complete protection for your roof and your electrical network.

Why choose the HMS-1600-4T for your solar panels?

  • Superior energy efficiency: MPPT tracking and management at the panel level to capture every last bit of sunlight.
  • Unfailing reliability: Robust outdoor design certified to IP67, capable of operating in extreme conditions from -40 °C to +65 °C.
  • Smart energy management: Includes reactive power control and remains fully compatible with the S-Miles Cloud global monitoring platform.
  • Full regulatory compliance: Certified to the strictest European and French standards (EN 50549-1:2019, VDE-AR-N 4105:2018, VFR2019).

Ideal use: This micro-inverter is perfect for residential rooftop solar installations, sheds or ground-mounted systems requiring a high-performance, secure and centralised panel array managed via a single control unit.

Important note: For remote data analysis and app monitoring, a Hoymiles DTU (Sub-1G) communication gateway and suitable AC connection cables are required and sold separately.






FAQ - Hoymiles HMS-1600-4T Micro-inverter

1. What is the advantage of this micro-inverter’s “4-in-1” design? +
The 4-in-1 design means that this single unit can independently receive and manage up to 4 solar panels simultaneously. For your installation, this significantly reduces installation time, simplifies wiring on the roof and lowers the overall cost of equipment compared to purchasing four individual micro-inverters.
2. How does the device handle shading on one of the panels? +
The HMS-1600-4T incorporates 4 fully independent MPPT trackers (one dedicated circuit per panel). If a panel is shaded (by a chimney, tree or cloud) or becomes dirty, the drop in output remains isolated. The other three connected panels continue to generate electricity at 100% of their full potential, unlike a centralised inverter.
3. Do I need a DTU communication gateway for this model? +
Yes, a Hoymiles DTU gateway (Sub-1G technology) is required to configure the micro-inverter, monitor your performance remotely and access the S-Miles Cloud app or platform. Sub-1G radio technology offers superior transmission stability over long distances, even through structural obstacles in buildings.
4. What is the power range of compatible solar panels? +
This micro-inverter supports the latest generation of solar panels with power ratings between 320 W and 540 W (and above). You should check that your panels comply with the maximum input voltage of 65 V and the maximum input current of 14 A per DC input.
5. Does the micro-inverter include safety features to protect the electrical safety of my roof? +
Absolutely. Safety is at the heart of Hoymiles’ engineering. The device incorporates a high-frequency transformer with full galvanic isolation to isolate the circuits. Furthermore, it is natively compliant withrapid shutdown protocols, ensuring the immediate safety of your grid and your roof in the event of a fault.
6. Does it comply with European and French feed-in standards? +
Yes, the HMS-1600-4T has all the regulatory certifications required for official connection to the electricity grid. It complies with the strictest European and French directives, notably standards EN 50549-1:2019, VDE-AR-N 4105:2018 and the VFR 2019 decoupling recommendation.
7. How does the device cool itself and withstand harsh outdoor conditions? +
The micro-inverter is designed for outdoor installation, directly beneath the solar panels. Its waterproof housing is IP67-certified (total protection against dust and heavy water jets). Cooling is achieved by natural convection without any fans, ensuring completely silent operation from -40 °C to +65 °C with no moving parts.
8. What essential optional components need to be ordered separately? +
To commission your installation, you must add the optional AC connection cable for the HMS series (available in various lengths depending on the distance to your electrical box or connection point). The Hoymiles DTU gateway is also sold separately to enable connected monitoring.
