Hoymiles HiFlow 800 HF-800-WB WiF Micro Inverter 800W

The HF-800-WB from Hoymiles (MPN: HF-800-WB) is a powerful and cost-effective microinverter for balcony, patio, or garden solar installations and small PV systems in residential buildings. It stands out thanks to its compact, lightweight design, exceptionally simple plug-and-play installation, high MPPT efficiency of 99.8% for optimal module utilization, and an integrated Wi-Fi and Bluetooth module for direct monitoring without additional hardware. With an IP67 protection rating and instant voltage shutdown, the inverter offers maximum system safety and durability. Smart system connectivity via app and cloud, flexible integration into smart home systems, and its fanless, robust design make this inverter a future-proof solution for residential applications.

What makes the HF-800-WB special?

• Compact design: Extremely lightweight and space-saving—ideal for residential buildings and balcony installations
• Efficient power generation: MPPT efficiency of 99.8% and peak efficiency of 97% for maximum energy yield
• Smart control: Integrated Wi-Fi and Bluetooth modules for direct app or cloud control without a separate data box or registration
• Easy setup: Plug-and-play with the Flex-S3 cable system, quick connection without complex electrical work
• Maximum safety: IP67 protection rating, immediate voltage cut-off to 34 V within 1 second, durable and safe technology
• Silent, maintenance-free technology: Fanless cooling system, robust for indoor and outdoor use

Smart Monitoring & Easy Control – Greater Flexibility via Wi-Fi & Bluetooth

Thanks to its integrated Wi-Fi and Bluetooth modules, the HF-800-WB 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. Device management is particularly user-friendly, as no separate registration is required. Compared to older models without Bluetooth, the HF-800-WB thus offers additional flexibility, for example, for installation sites without a stable network. Plug-and-play installation, as well as secure, data-protected monitoring and control directly from a smartphone, are guaranteed at all times.

Durability 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 immediate voltage shutdown and the well-designed safety concept 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 unit—done. This reduces installation effort and potential sources of error, making it an attractive option even for DIY solar projects.
