Hoymiles HiFlow 1600 Pro HMS-1600-4WB 1600W Microinverter Pro

The HMS-1600-4WB from Hoymiles (MPN: HMS-1600-4WB) is a high-performance 2-in-1 microinverter designed for balcony, patio, or garden solar installations and small PV systems. It stands out with its exceptionally simple plug-and-play installation, four independent MPPT inputs for optimal module utilization, an integrated Wi-Fi and Bluetooth module for direct monitoring without additional hardware, and maximum system security thanks to IP67 protection, an isolated transformer, and certified cybersecurity. Smart system connectivity via app and cloud, flexible integration into the smart home, and the fanless, robust design make the device a future-proof solution for both residential and professional applications.

What makes the HMS-1600-4WB special?

• Smart control: Integrated Wi-Fi and Bluetooth for direct app or cloud control without a separate data box
• Easy commissioning: Plug-and-play with Flex-S3 cable system, quick connection without complex electrical work
• Maximum safety: IP67 protection rating, fast emergency shutdown, isolated circuitry, and data protection in accordance with ETSI EN 303 645
• Silent, maintenance-free technology: Fanless cooling system, robust for indoor and outdoor use
• 12-year warranty: learnmore here

Smart monitoring & easy control – More flexibility thanks to Bluetooth

Thanks to the integrated Wi-Fi and Bluetooth module, the HMS-1600-4WB can be flexibly monitored and controlled: via the S-Miles Home app, both a local connection via Bluetooth—even without Wi-Fi or internet—and global access via the S-Miles Cloud are possible. This makes configuration particularly easy and ensures full transparency at all times. Compared to the previous model, which operates exclusively via Wi-Fi, the HMS-1600-4WB thus offers additional flexibility, for example for system locations without a stable network. Both models do not require a separate DTU and enable plug-and-play installation as well as modern, data-secure monitoring and control directly from a smartphone.

Robustness and Safety for Continuous Operation

With an IP67 protection rating, the inverter is completely dust- and waterproof. The passive convection cooling operates fanless and maintenance-free. The rapid shutdown function and the isolated transformer ensure a high level of personal safety and comply with current standards for grid and system safety.

Plug-and-play design – Ready for use in just a few minutes

The Flex-S3 cabling system allows for simple and safe commissioning: connect to the solar modules and the household outlet, start the device, and you’re done. This reduces installation effort and sources of error, making it an attractive option even for DIY solar projects.
