Three-Phase Solar + Storage Inverter
The HYXiPOWER H15K-25K-HT is a three-phase hybrid inverter range built for larger residential properties, commercial sites, and advanced energy storage systems.
Designed to manage solar generation, battery charging, backup power, and grid interaction in one integrated platform, the series is aimed at users with higher energy demands or more complex solar installations.
With support for large PV arrays, fast battery charging, generator integration, and UPS-grade backup switching, the H15K-25K-HT series is designed for systems focused on energy independence, backup resilience, and smart energy management.
For larger hybrid solar installations, this inverter series acts as the central energy management hub.
What is the HYXiPOWER H15K-25K-HT Hybrid Inverter?
The HYXiPOWER H15K-25K-HT is a three-phase hybrid inverter series available in 15 kW, 20 kW, and 25 kW models.
It connects solar panels, battery storage systems, the electricity grid, and optional generators into one integrated energy system.
The inverter converts solar energy for on-site use, stores excess generation in batteries, and automatically switches to backup operation during grid outages.
Unlike standard commercial string inverters, this system is designed to manage both solar generation and battery storage, making it suitable for larger hybrid and backup-capable installations.
