Fronius SYMO12.5-3-M Light 12.5 kW 3-phase

The Fronius Symo 12.5-3-M Light is a three-phase grid-connected inverter designed for small-scale self-consumption systems. This transformerless inverter features two MPPTs (maximum power point trackers) and a flexible design, making it suitable for installations on irregular surfaces and roofs with different orientations. The Light version does not include WLAN communication but is ready for future integration if required. The inverter includes a meter interface for dynamic power management and consumption monitoring. It supports zero-feed-in functionality, reducing inverter output when solar production exceeds consumption to prevent energy from being fed into the grid. The unit operates across a DC input voltage range of 200–1,000 V and is compatible with standard grid connections at 3-NPE 400 V/230 V or 3~NPE 380 V/220 V.
