SolaX X3-Forth 100kW HV 3‑Phase Inverter

Key benefits

  • 100kW three‑phase inverter for large commercial and industrial PV systems where centralised, grid‑tied generation is required.
  • Supports up to 150% PV oversizing and 110% overloading output to maximise yield from available roof, carport or ground‑mount space.
  • Nine MPPTs with two strings per tracker, enabling flexible string design across multiple orientations and partially shaded areas.

Brief description

The SolaX X3‑Forth 100.0kW 3‑Phase Inverter is part of the X3‑Forth range, designed for large‑scale commercial and industrial solar installations. With up to 150kWp PV input on the 100kW model, a wide 180–1000V MPPT range and high conversion efficiency, it suits logistics hubs, factories, business parks and solar carports aiming to reduce grid import. Built‑in export power control, remote configuration, 24‑hour monitoring and Smart I‑V Curve Diagnosis help operators manage performance and maintenance over the long term.

Key features

  • Maximum efficiency up to 98.6% with MPPT efficiency of 99.9% on X3‑Forth standard‑voltage models.
  • 180–1000Vdc MPPT voltage range, maximum 32A per MPPT and up to 46A short‑circuit current per MPPT.
  • Fuse‑free design with smart string current monitoring and Smart I‑V Curve Diagnosis for faster fault location.
  • IP66 enclosure with Type II AC/DC surge protection as standard, optional Type I+II SPD and AFCI for enhanced protection.
  • Smart air cooling, AC terminal temperature detection and optional PLC communication to support demanding C&I sites.
