As solar installations continue to expand in capacity and complexity, inverter technology is becoming increasingly important in determining overall system performance, operational reliability and long-term energy generation. HYXI addresses these requirements with its 250–350kW three-phase string inverter series, designed to support high-capacity photovoltaic installations through advanced power conversion, intelligent monitoring and integrated protection features.
The HYX-S350K-HT model combines high-power handling capabilities with smart operational functions, making it a solution for large commercial, industrial and utility-scale solar applications.
High Efficiency and Optimised Energy Generation
At the core of the inverter’s performance is its high-efficiency conversion architecture, delivering a maximum efficiency exceeding 99.03% and European weighted efficiency above 98.8%. These specifications are intended to minimise conversion losses and support improved energy output across solar installations.
The inverter supports a maximum DC input voltage of 1,500V and features six Maximum Power Point Trackers (MPPTs), each accommodating up to five string inputs. With a maximum input current of 75A per MPPT, the system is designed to work with high-power photovoltaic modules.
HYXI also incorporates AI-based dynamic MPPT technology, which the company states can increase power generation by 5%, supporting improved energy harvesting under varying operating conditions.
Advanced Protection and Grid Compatibility
Safety and grid integration are important considerations for high-capacity solar projects. The inverter incorporates smart string-level disconnection, with a shutdown response of less than 25 milliseconds, alongside terminal overheat protection and smart connector-level detection.
Its IP66-rated enclosure provides protection against dust and water ingress, while the product has undergone more than 1,400 cumulative rigorous tests, according to HYXI.
For grid-connected applications, the inverter maintains total harmonic current distortion below 3% and supports a short-circuit ratio greater than 1.2, contributing to power quality and operation under weak-grid conditions.
Intelligent Monitoring for Efficient Operations
The inverter integrates AI-based current-voltage (IV) curve scanning and fault diagnosis to support system monitoring and troubleshooting. Real-time monitoring, combined with online maintenance capabilities, enables operators to identify potential performance issues and streamline maintenance activities.
An optional anti-PID function further supports photovoltaic system performance management.
Supporting High-Capacity Solar Development
With smart air cooling, an 800V nominal AC output and an operating altitude capability of up to 5,000 metres, the HYXI 350kW inverter brings together high-power conversion, operational intelligence and comprehensive protection.
Its combination of efficiency, safety and digital management capabilities positions it as a technology option for developers and operators seeking reliable inverter solutions for increasingly demanding solar installations.
