Three Phase Inverter

FORTH G3

  • 80kW / 99.9kW / 100kW / 110kW / 125kW

FORTH G3 is a three-phase C&I on-grid inverter designed for easier operation, maintenance, and system expansion. Its removable self-cleaning fan helps reduce O&M costs, while up to 10 units can operate in parallel without an external EMS.

Product Advantage

Engineered for high-performance commercial PV systems, FORTH G3 delivers up to 98.8% efficiency and is up to 20% lighter with SiC technology. A maximum 52A input current per MPPT supports a wide range of high-current PV modules, while full-power output up to 45°C ensures reliable operation in demanding conditions.

High Efficiency

  • Max. 98.8% efficiency, up to 20% lighter with SiC technology

  • Max. 52A input current per MPPT, compatible with almost all PV modules

  • Full power output up to 45°C* (Full power maintained under rated operating conditions.)


Assured Safety

  • Auto-trip switch standard, AI-powered AFCI (500m range / 0.5s trip, optional)

  • Type II DC/AC SPD (DC-side Type I+II optional) for lightning protection

  • DC/AC terminal temperature and internal humidity monitoring


Intelligent Design

  • Removable self-cleaning fan for lower O&M cost

  • Up to 10-unit parallel operation without external EMS

  • Online I-V curve scanning for smart string fault diagnosis


Flexible Adaptability

  • Three-phase unbalanced output for precise power control (optional)

  • Genset fuel-saving with auto start-stop support

  • IP66 ingress protection and C5 corrosion resistance for harsh environments

  • AC-side aluminum wiring compatibility for lower BOS cost
