Single-Phase Solar + Storage Inverter
The HYXiPOWER H3K-8K-HS is a single-phase hybrid inverter range built for households combining solar with battery storage.
Designed to manage solar generation, battery charging, backup power, and grid interaction in one unit, it gives homeowners greater control over how energy is produced, stored, and used.
With wide MPPT operating ranges, high PV oversizing support, fast UPS-grade switching, and intelligent energy management, the H3K-8K-HS series is designed for homes looking to improve energy independence while maintaining backup capability during outages.
For households building a hybrid solar system from the ground up, this inverter series acts as the central hub of the setup.
What is the HYXiPOWER H3K-8K-HS Hybrid Inverter?
The HYXiPOWER H3K-8K-HS is a single-phase hybrid inverter series available in sizes from 3 kW to 8 kW.
It connects solar panels, batteries, the grid, and optional generators into one integrated energy system.
The inverter converts solar energy for household use, stores excess generation in compatible battery systems, and automatically switches to backup operation when grid power is interrupted.
Unlike a standard string inverter, the H3K-8K-HS is designed to manage both energy conversion and battery storage, making it suitable for modern solar-plus-storage systems.
