Product Description

The Solax FORTH 120000W X3-FTH-120K-G2 Three-phase Solar Inverter expands the FORTH platform with 12 MPPT for large-scale projects that require maximum granularity in tracking and reduced mismatch losses. Its IP66 enclosure, intelligent active ventilation, and high-performance electronics allow full-load operation in demanding environments, with I-V diagnostics and remote management for fast and cost-effective O&M.

Main Features

12 MPPT with 2 inputs per tracker (24 strings) and current reading per string.
Max. efficiency 98.6%; THDi <3%; adjustable power factor.
150% PV oversizing (up to ≈180 kWp) and 110% AC output to take advantage of peak irradiation.
MPPT range 180–1000 V; max. DC voltage 1100 V; current per MPPT 32 A (Isc 46 A).
Industrial safety: IP66, SPD Type II on DC/AC (Type I+II optional), anti-islanding, RCMU, and optional AFCI.
Grid functions: zero export, reactive power control also in night mode, and optional PLC support.

Advantages or Benefits

Ultra-flexible design with 12 MPPT for complex rooftops and plants with multiple orientations.
More annual energy thanks to high efficiency and 150% peak DC power.
More efficient O&M through I-V diagnostics, global MPP scan, and remote firmware updates.
Easy integration with Solax Cloud and third-party SCADA via RS485/Modbus or optional PLC.
Superior robustness and availability in extreme climates with intelligent active ventilation.

Purpose or Applications

Ideal for large-scale commercial/industrial plants, extensive rooftops, agrivoltaics, and high-power carports where 120 kW per block is required with detailed string control and strict grid quality compliance.
