Note: X3 revision of the MOD 12KTL3-X, and the difference is real: both MPPTs are 20 A with one string each, where the X model uses asymmetric 13 A and 26 A trackers. Symmetric trackers make string design simpler and let you mirror two roof faces. Nominal DC 600 V against the X model's 580 V. Also lighter at 14.8 kg and quieter at 29 dB. Same 98.6% peak efficiency and 98.1% European. 1100 V ceiling, 140-1000 V window, IP66, 4000 m. Grid-tie only.
