Note: Grid-tie only - no battery, no backup. Steps up from the X3-MIC on every input figure: 1100 V DC ceiling against 1000 V, 32 A per tracker against 16 A, and two strings per tracker as standard (32/32 A across 2 MPPTs here). MPPT window 160-980 V, nominal 650 V. Maximum apparent power 22000 VA, maximum output current 33.6 A. Peak efficiency 98.30%, European 97.80%. 26 kg, IP66, -30 to +60 degC, altitude to 4000 m. Natural cooling on the smaller units and smart fan cooling higher up; typical noise under 55 dB. AFCI and AC auxiliary supply are optional.
