Three-Phase Solar Inverter
The HYXiPOWER S15K–25K-T is a three-phase string inverter range built for larger-scale solar installations with higher generation requirements.
Designed for large homes, commercial properties, and high-consumption sites, the series focuses on efficient solar conversion, flexible system design, and operational reliability without the added complexity of battery storage or hybrid energy management.
Unlike hybrid systems, the S15K–25K-T is dedicated purely to solar generation and grid interaction. It is aimed at installations where the priority is maximising solar production across larger arrays while maintaining streamlined system operation.
For larger solar-only systems, this inverter series acts as the central conversion platform between solar generation and usable site electricity.
What is the HYXiPOWER S15K–25K-T String Inverter?
The HYXiPOWER S15K–25K-T is a three-phase string inverter series available in sizes from 15 kW to 25 kW.
It converts DC electricity generated by solar panels into AC electricity for use across three-phase electrical systems commonly found in larger residential and commercial properties.
The inverter is designed specifically for grid-connected solar systems without integrated battery storage, focusing on efficient energy conversion, intelligent monitoring, and scalable system performance.
The series is positioned for installations requiring larger solar capacity and more flexible system design than standard residential inverters.
