Solax 125KW On-Grid Solar inverter

The latest Solax 125KW On-Grid Solar inverter price in Pakistan is Rs. 1,470,000/- updated on August 30, 2026.

Overview:

The Solax 125KW On-Grid Solar inverter is confirmed, via SolaX’s own official datasheet (fetched directly this session), as the X3-FTH-125K model — the largest confirmed tier in the X3-FORTH three-phase commercial and industrial on-grid range (75/80/100/110/120/125kW, extending to 136/150kW in some markets).

Max. recommended PV array power is 188kWp at up to 1,100Vdc max input voltage, with 12 MPP trackers (2 strings each) and 32A max input current / 46A max short-circuit current per tracker across an 180–1000Vdc MPPT range.

Rated output apparent power is 125kVA at up to 200A@220V or 191.4A@230V, with max apparent output reaching 132kVA. Adjustable power factor spans 0.8 lagging to 0.8 leading, and maximum efficiency reaches a class-leading 98.6% (98.3% European efficiency). The IP66-rated enclosure operates from -25°C to +60°C up to 4,000m altitude, weighs 87kg, and communicates over RS485/DRM with under 10W night-time power consumption.
