Note: Grid feed-in is documented on the datasheet, so this model can be net-metered. Three-phase 380/400 V output on a low-voltage 40-60 V battery - the combination most Pakistani three-phase homes want, since it takes the banks already sold here rather than a high-voltage stack. 250 A charge and discharge. Asymmetric MPPTs at 26 A and 17 A with 2+1 strings, so the trackers are not interchangeable. Full-load DC window 260-650 V inside a wider 200-700 V MPPT range. Maximum AC output 13200 W. Peak efficiency 97.9%, European 96.9%. IP65, -45 to +60 degC. PV arc-fault detection and lightning protection. 5-year warranty.
