Hoymiles HiFlow 1000 Pro HMS-1000-2WB Microinverter 1000W Pro

The HMS-1000-2WB from Hoymiles (MPN: HMS-1000-2WB) is a compact 2-in-1 microinverter for balcony, patio, and small PV systems. Installation is particularly easy thanks to its plug-and-play design. Two independent MPPT inputs ensure optimal module performance. With built-in Wi-Fi and Bluetooth, you can conveniently monitor your system via an app, without the need for any additional devices. The robust, fanless design, IP67 protection rating, and certified cybersecurity offer the highest level of reliability. Ideal for both residential and commercial applications, the device can be flexibly integrated into a smart home.

What makes the HMS-1000-2WB special?

• Dual Module Control: Two independent MPPT trackers for efficient energy yield—even in shaded conditions or with mixed module types
• Smart control: Built-in 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: Longevity guaranteed directly by the manufacturer. Find it here !

Smart Monitoring & Easy Control – Greater Flexibility with Bluetooth

Thanks to the integrated Wi-Fi and Bluetooth modules, the inverter 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-1000W-2T, which operates exclusively via Wi-Fi, the HMS-1000-2WB 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 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 to Use in Just a Few Minutes

The Flex-S3 cabling system enables 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 potential sources of error, making it an attractive option even for DIY solar projects.
