Solar Inverter / Hybrid Inverter | Three Phase Hybrid Storage Inverter 3-15 kW

Three Phase Hybrid Storage Inverter 3-15 kW


The VOLTARIX High Voltage Series Three-Phase Storage Inverters are designed to enhance energy independence for both residential and commercial users. With a power range from 3 kW to 15 kW, these inverters are fully compatible with high-voltage (80–600 V) battery systems, delivering flexible and efficient energy storage performance. Featuring advanced energy management, the system operates based on time-of-use and demand charge rate structures — effectively reducing electricity purchases from the public grid and maximizing self-consumption.

Thanks to the UPS function (switching time < 10 ms), critical loads remain powered seamlessly during grid outages. Under backup operation mode, the inverter delivers up to 150% peak output overloading, ensuring reliable power continuity even under heavy demand.

The VOLTARIX Smart Energy Management Platform incorporates Dynamic Electricity Pricing & Automation, a real-time optimization tool that continuously monitors electricity price fluctuations and automatically adjusts inverter operation for maximum efficiency. Operating 24/7 fully autonomously, it enables users to reduce energy costs, optimize power utilization, and achieve greater energy independence — all without manual intervention.
