Collection: Three-phase grid-tied inverters

Three-phase string inverters, from small residential systems to large industrial plants: Fronius Symo 3.0-3-M at 3 kW with two MPPTs, FoxESS T17 G3 at 17 kW with two MPPTs, up to the SolarEdge Synergy SE100K and SE120K at 100 and 120 kW with three SESUK units.

Above 50 kW the architecture changes: Synergy inverters are made of several independent units under a single interface, so a fault stops part of the plant rather than all of it. On large arrays that redundancy is worth more than a point of efficiency.

For connection, what counts is the voltage level of the connection point: low voltage falls under CEI 0-21, while plants requiring medium voltage fall under CEI 0-16.
