Fronius | Solar Inverter 10kW 3-Phase Dual MPPT | IP66 Outdoor Rated
The Fronius SYMO10.0-3-M is a 10kW three-phase grid-tie solar inverter with two independent MPP trackers. The SYMO10.0-3-M converts DC from a solar array into 400V three-phase AC, with a 10,000W nominal output and a maximum efficiency of 98%. It is a transformerless inverter rated IP66 for indoor or outdoor installation, and complies with IEC 62109-1/-2.
Australian roofs rarely offer one clean, unshaded plane facing north. Panels split across east and west faces, or around obstructions, produce different string voltages that a single tracker cannot optimise. Rooftop inverters also sit through heat, dust, and storms year-round. The Fronius SYMO10.0-3-M runs two independent MPP trackers across 3+3 DC inputs, carries an IP66 rating for outdoor mounting, and operates from -40 to +60 degrees C.
Solar installers value an inverter that fits the roof in front of them rather than forcing a compromise. The dual-tracker SuperFlex design handles multi-orientation arrays, and the system can be oversized to 25kWp to lift yield per inverter. The SnapINverter wall bracket lets one person hang and connect the unit, and the integrated DC disconnector is built into the inverter housing. Fronius Solar.web logging means the system reports its own output for years with little on-site attention.
Features
- 10kW three-phase output — the SYMO10.0-3-M delivers 10,000W of nominal AC power at 14.4A across a 400V three-phase grid connection.
- Dual MPP trackers — two independent trackers with 3+3 DC inputs let panels on different orientations run at their own optimum.
- 200 to 900V DC input — the wide DC window, with a usable MPP range of 270 to 800V, suits a range of string lengths and layouts.
- Oversizing to 25kWp — the inverter accepts up to 25kWpeak of panels, so installers can load extra DC for stronger year-round yield.
- 98% peak efficiency — a maximum efficiency of 98% and 97.4% European efficiency keep conversion losses low across the day.
- IP66 indoor or outdoor — the SYMO10.0-3-M is rated IP66 and runs from -40 to +60 degrees C for wall mounting inside or out.
- Transformerless design — the transformerless topology holds weight to 34.8kg and supports the high conversion efficiency.
- Integrated protection — a built-in DC disconnector, DC insulation measurement, and reverse polarity protection are part of the inverter.
- SnapINverter wall mount — the SnapINverter bracket mounts to the wall first, then the inverter hangs and clicks onto it for service access.
- Solar.web monitoring — WLAN and Ethernet connect to Fronius Solar.web, with Modbus TCP SunSpec and an included datalogger and webserver.
- Screw-terminal connections — DC uses 6x DC+ and 6x DC- screw terminals and AC uses 5-pole screw terminals, both 2.5 to 16mm2.
- Requires accredited installation — the SYMO10.0-3-M is a grid-tie inverter that must be installed and grid-connected by an accredited professional.
Where to use
- Three-phase homes — a 10kW inverter for residential properties with a three-phase supply and a larger rooftop array.
- Multi-orientation roofs — the SYMO10.0-3-M runs east and west or split arrays on separate trackers without dragging both to one voltage.
- Small commercial rooftops — shops, sheds, and small business premises running a 10kW three-phase PV system.
- Oversized DC arrays — installs that load up to 25kWp of panels onto one inverter for stronger morning and afternoon output.
- Split or shaded layouts — the SYMO10.0-3-M suits roofs with obstructions, dormers, or partial shade across separate strings.
- Monitored solar fleets — installers running Fronius Solar.web across multiple sites for remote output data.
- Outdoor wall mounting — the IP66 housing allows external wall mounting where indoor space is limited.
The Fronius SYMO10.0-3-M is a grid-tie string inverter, not a hybrid unit, so it does not connect a battery on its own. It must be installed and grid-connected by an accredited professional under the relevant network and wiring rules. The inverter suits three-phase supplies only and is not intended for single-phase connections.
