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 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 smart home systems, and the fanless, robust design make this 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 setup: Plug-and-play with the Flex-S3 cabling system; quick connection without complex electrical work
• Maximum safety: IP67 protection rating, rapid emergency shutdown, isolated circuitry, and data protection in accordance with ETSI EN 303 645
• Silent, maintenance-free technology: Fanless cooling system, rugged enough for indoor and outdoor use
• 12-year warranty: Learnmore here

Smart Monitoring & Easy Control—More Flexibility with Bluetooth

Thanks to its integrated Wi-Fi and Bluetooth modules, the HMS-1600-4WB can be flexibly monitored and controlled: The S-Miles Home app enables both a local connection via Bluetooth—even without Wi-Fi or an internet connection—and global access via the S-Miles Cloud. 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.

Ruggedness and Safety for Continuous Operation

With an IP67 rating, the inverter is completely dust- and waterproof. The passive convection cooling operates fanlessly and requires no maintenance. 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 to Use in Just a Few Minutes

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