The HMS-800-2WB from Hoymiles (MPN: HMS-800-2WB) is a powerful 2-in-1 micro inverter for balcony, terrace, or garden solar installations and small PV systems. It scores with particularly easy plug-and-play installation, two independent MPPT inputs for optimal module utilization, integrated Wi-Fi and Bluetooth modules for direct monitoring without additional hardware, and maximum system safety thanks to IP67 protection, an isolated transformer, and certified cybersecurity. Smart system connection via app and cloud, flexible integration into the smart home, and a fanless, robust design make the device a future-proof solution for both private and professional applications.
What makes the HMS-800-2WB special?
Dual module control: Two independent MPPT for efficient energy yield – even in shaded conditions or with different modules
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, 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: Durability guaranteed directly by the manufacturer. You can find it here !
Smart monitoring & easy control – more flexibility thanks to Bluetooth
Thanks to the integrated Wi-Fi and Bluetooth module, the HMS-800-2WB can be flexibly monitored and controlled: The S-Miles Home app enables both a local connection via Bluetooth – even without Wi-Fi or the internet – and worldwide access via the S-Miles Cloud. This makes configuration particularly easy and ensures full transparency at all times. Compared to the HMS-800W, which works exclusively with Wi-Fi, the HMS-800-2WB 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 your smartphone.
Robustness and safety for continuous use
With IP67 protection, the inverter is completely dustproof and waterproof. The passive convection cooling system is fanless and maintenance-free. The fast 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 cable system allows for easy 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 attractive for DIY solar projects as well.
