Fronius Verto 25.0 Plus SPD 1+2 Hybrid Inverter 25 kW Three-Phase 4,210,456
The Fronius Verto 25.0 Plus SPD 1+2 (item code 4,210,456) is a three-phase 25 kW hybrid inverter from the commercial Verto Plus family, with 3 MPPT trackers and a PV array of up to 37.5 kWp. It is designed for medium-sized commercial and industrial systems that want to integrate high-voltage (150-700 V) storage without changing the system architecture.
The SPD 1+2 designation indicates the integrated type 1+2 surge protection, which protects the system against direct and indirect lightning strikes without additional switchboards. The enclosure is IP66 with active cooling and an operating temperature from -40 to +60 °C; communication includes Ethernet LAN, WLAN and 2x RS485 Modbus RTU SunSpec, plus an integrated datalogger and web server.
