Hoymiles HiFlow 800 Pro HMS-800-2WB 800W Microinverter Pro

The HMS-800-2WB from Hoymiles (MPN: HMS-800-2WB) is a high-performance 2-in-1 microinverter for balcony, patio, or garden solar installations and small PV systems. It stands out for its exceptionally simple plug-and-play installation, two independent MPPT inputs for optimal module utilization, an integrated Wi-Fi and Bluetooth module for direct monitoring without additional hardware, and maximum system safety 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 this device a future-proof solution for both residential and professional applications.

What makes the HMS-800-2WB special?

• Dual module control: Two independent MPPT trackers for efficient energy yield—even in shaded conditions or with different types of modules
• 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 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, rugged enough for indoor and outdoor use
• 12-year warranty: Durability guaranteed directly by the manufacturer. Find it here !

Smart Monitoring & Easy Control—More Flexibility with Bluetooth

Thanks to its integrated Wi-Fi and Bluetooth modules, the HMS-800-2WB can be flexibly monitored and controlled: Using the S-Miles Home app, you can establish a local connection via Bluetooth—even without Wi-Fi or an internet connection—as well as access the system globally via the S-Miles Cloud. This makes configuration particularly easy and ensures full transparency at all times. Compared to the HMS-800W, which operates exclusively via Wi-Fi, the HMS-800-2WB 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 system 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 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—done. This reduces installation effort and potential sources of error, making it an attractive option even for DIY solar projects.
