Note: Grid export is documented on the datasheet, so this model can be net-metered. 200% PV oversizing allowed - 16,000 W of array on a 10 kW inverter - across three MPPTs with two strings each. Input currents are asymmetric at 30 A, 22 A and 22 A, so the trackers are not interchangeable. Full-load MPPT window is 200-480 V inside a wider 70-540 V range on a 600 V ceiling. 48 V bank with an unusually wide 40-64 V window and 210 A charge and discharge, 10,000 W each way. Output is staged: 10,000 VA nominal, 15,000 VA for 60 s, 20,000 VA for 1 s. Supports AC-coupled solar input and a dedicated generator connection. Stacks to 9 units. IP66, transformerless PV-to-grid but transformer-isolated battery-to-grid. 35 kg, smart cooled at 45 dB. Street price in Pakistan Rs 425,000 to Rs 440,000 (c-power.pk Rs 425,000; buysolar.pk Rs 440,000, read 22 Aug 2026).
