The Hoymiles HF-800-WB WiFi is a single-phase microinverter from the HiFlow Series, designed for residential photovoltaic systems with a rated AC output power of 800 VA. It features one MPPT and one PV input and is suitable for commonly used solar modules in the approximately 320 to 520 W+ power range. With built-in 2.4 GHz Wi-Fi and Bluetooth communication, the HF-800-WB can connect directly to the Hoymiles S-Miles Cloud monitoring platform without requiring an additional DTU. Bluetooth also enables local device monitoring and configuration through the supported app. The microinverter uses fanless natural convection cooling and delivers a peak efficiency of up to 97% and nominal MPPT efficiency of up to 99.8%, supporting efficient energy conversion. Its IP67 outdoor protection rating and operating temperature range of -40°C to +65°C make it suitable for a wide range of outdoor PV installation environments. The compact unit measures approximately 213 × 182.5 × 36.5 mm and weighs around 2.1 kg, while the Flex-S3 plug-and-play AC connection helps simplify system installation.
