The 120kW Solar Industrial-Frequency Three-Phase Inverter is a heavy-duty, industrial-grade power conversion solution built for continuous, high-load operation in harsh environments. Designed for large-scale commercial and industrial solar projects, it delivers stable, pure sine wave three-phase power to factories, hotels, resorts, and island microgrids.
Built with industrial-frequency transformers, it offers superior voltage regulation, surge protection, and long-term reliability compared to high-frequency inverters, making it ideal for the unstable grids and tropical climates of the Caribbean and coastal regions.
Features & Advantages
✅ Industrial-Frequency Transformer Design
Built-in low-frequency transformer provides :
✅ 120kW Continuous Three-Phase Power Output
Rated 120kW three-phase power supports heavy industrial machinery, central AC systems, and full-facility loads. Supports parallel connection for system expansion, up to multiple units for MW-level projects.
✅ Pure Sine Wave Output for Sensitive
Equipment Clean, stable power ensures no damage to motors, compressors, computers, and precision electronics. Eliminates noise, heat, and equipment wear caused by modified sine wave inverters.
✅ Hybrid & Off-Grid Operation Ready
Works seamlessly with solar panels, battery banks, and utility grids:
Grid-tie mode: Feed excess power back to the grid (where permitted)
Off-grid mode: Operate independently during blackouts
Hybrid mode: Combine solar, battery, and grid power for maximum reliability
✅ Tropical & Coastal Environment Adaptability
Anti-corrosion coated cabinet
High-temperature resistant components
IP21 (indoor) / optional IP54 (outdoor) protection
Operates reliably in high humidity, salt spray, and extreme heat conditions
✅ Advanced Protection & Safety Features
Built-in safeguards against overvoltage, undervoltage, overcurrent, short circuit, overheating, and reverse polarity. Automatic shutdown and alarm functions prevent equipment damage.
✅ Smart Monitoring & Control
Large LCD touchscreen for real-time system data
Optional remote monitoring via RS485, Ethernet, or Wi-Fi
Programmable operation modes for self-consumption, peak shaving, and backup power
