Solar Inverter | Three Phase
The HYXiPOWER S8-12K-T is a three-phase string inverter built for residential and small commercial solar systems that need higher capacity and stable output.
Designed for efficiency and durability, it converts solar energy into usable electricity while handling larger system sizes with ease.
With strong DC oversizing capability, wide MPPT range, and advanced safety features, it’s suited to installations where performance and reliability matter.
For properties running three-phase power, this inverter provides a solid foundation for consistent solar generation.
What is the HYXiPOWER S8-12K-T?
The S8-12K-T is a three-phase string inverter designed to convert DC electricity from solar panels into AC power for use in homes or businesses.
It supports multiple MPPT inputs, allowing different panel orientations or roof sections to operate efficiently within the same system.
Unlike hybrid inverters, this model does not manage battery storage directly and is focused purely on solar generation and grid interaction.
Key features of the HYXiPOWER S8-12K-T
High DC oversizing capability
Supports up to 160% DC oversizing, allowing larger solar arrays to maximise energy generation throughout the day.
High conversion efficiency
Delivers up to 98.5% efficiency, helping reduce energy losses during conversion.
Wide MPPT voltage range
Maintains strong performance across varying sunlight conditions and system configurations.
Dual MPPT tracking
Allows panels across different roof angles or orientations to operate independently for better output.
Advanced arc fault protection (AFCI)
Detects faults across the system and shuts down rapidly to improve safety.
Type II surge protection
Includes built-in DC and AC surge protection to safeguard against electrical spikes.
Smart monitoring and diagnostics
Offers real-time data tracking, app-based monitoring, and system diagnostics for easier management.
IP66-rated enclosure
Designed for outdoor installation in harsh environments, with strong resistance to dust and water.
