Three-Phase Solar Inverter
The HYXiPOWER S7K–12K-S is a three-phase string inverter range built for properties that sit beyond standard residential solar.
Designed to handle higher system sizes and three-phase power requirements, the series is suited to larger homes, small businesses, and sites with greater daytime energy demand.
Unlike hybrid inverters, the S7K–12K-S focuses purely on solar generation. It converts energy from solar panels into usable electricity for on-site use or export to the grid, without managing battery storage or backup power.
For systems where the priority is reliable solar generation at scale, this inverter acts as the core conversion unit.
What is the HYXiPOWER S7K–12K-S String Inverter?
The HYXiPOWER S7K–12K-S is a three-phase string inverter series available in sizes from 7 kW to 12 kW.
It converts DC electricity from solar panels into AC electricity for use across three-phase electrical systems, which are common in larger residential and commercial properties.
The system is designed for solar-only applications, focusing on efficient energy conversion, stable performance, and system visibility.
