Hoymiles Introduces HiFlow Pro Plug-In Microinverter Compliant with UL 3700 Standard in the US Hoymiles announced the official release of its HiFlow Pro plug-in microinverter, the first DIY solar microinverter compliant with the UL 3700 standard that is developed specifically for plug-in photovoltaic (PIPV) systems. Designed for plug-and-play residential solar applications, HiFlow Pro maximizes energy yield and optimizes performance within limited installation spaces, such as balconies and compact rooftops. Plug-in solar systems have gained popularity in Europe by making solar energy accessible for homeowners and renters. As demand for similar solutions grows in the US, the market has highlighted the need for a dedicated safety framework beyond traditional rooftop PV. In response, UL 3700 was introduced—the first North American safety standard specifically designed for plug-in photovoltaic systems. It provides manufacturers with a clear certification pathway while offering utilities, authorities having jurisdiction (AHJs), and consumers a consistent benchmark for safe deployment. HiFlow Pro is optimized for residential plug-in PV applications to ensure maximum energy harvest. High energy yield enabled by industry-leading MPPT efficiency (99.8% static and 99.5% dynamic) and low-voltage operation, maximizing energy harvest under changing weather conditions. Plug-and-play setup and commissioning via Bluetooth and Wi-Fi in less than 60 seconds, simplifying installation and system setup. Type 6 enclosure rating with reliable operation from -40°C to +65°C; Backed by 250,000-hour reliability testing, it delivers dependable performance across diverse climates. It supports parallel operation of four microinverters installed in separate sockets, enabling flexible expansion up to 1,200 W total output power to satisfy different market needs and local regulations.
