Solax 15Kw On-Grid Solar Inverter

The latest Solax 15Kw On-Grid Solar Inverter price in Pakistan is Rs. 307,000/- updated on October 20, 2026.

The Solax 15Kw On-Grid Solar Inverter is the X3-PRO-15K-G2 model. It is part of the X3-PRO G2 range of three-phase on-grid inverters for homes and light commercial sites (8/10/12/15/17/20/25/30kW).

It is a pure grid-tied string inverter with no battery input. So it suits solar systems that work with the grid rather than batteries.

PV Input and Output

The max. recommended PV array power is 22.5kWp, at up to 1,100V max. input voltage. The operating range is 135–985V, while the MPPT range is 160–980V. It has 3 MPP trackers with 2 strings each, at up to 32A max. input current per tracker. In addition, a global MPP scan improves shade tolerance.

Rated output power is 15kW at 22.8 A. Meanwhile, max. apparent output is 16.5 kVA at 24.2 A continuous current. It also supports 150% DC oversizing and 110% AC overload.

Efficiency and Build

Maximum efficiency reaches 98.3%, with 97.8% European efficiency. The power factor adjusts from 0.8 lagging to 0.8 leading, and THDi stays under 3%. The IP66-rated enclosure uses Smart air cooling. It works from -30°C to +60°C, up to 4,000m altitude and at 0–100% relative humidity. The inverter weighs 26.0 kg. Furthermore, it has built-in export power control and intelligent load management. Optional 24-hour WiFi/LAN/4G monitoring is available through SolaXCloud.
