Solar Inverter / Hybrid Inverter |Three Phase Hybrid Storage Inverter7-12 kW (LV Battery Supported)

Three Phase Hybrid Storage Inverter 7-12 kW (LV Battery Supported)

The VOLTARIX Low Voltage Series Storage Inverters are engineered to enhance energy independence and reliability for modern homeowners.

With a power range from 7 kW to 12 kW, these inverters are fully compatible with low-voltage (40–60 V) batteries, offering safe, efficient, and flexible energy storage solutions.

The system’s intelligent energy management operates based on time-of-use and demand charge rate structures, which effectively minimize electricity purchases from the public grid and optimize self-consumption. Thanks to the UPS function (switching time < 10 ms), critical household loads remain continuously powered during grid outages. Additionally, under backup mode, the inverter provides up to 150% peak output overloading, ensuring stable operation even in demanding conditions.

The VOLTARIX Smart Energy Management Platform features Dynamic Electricity Pricing & Automation, a next-generation energy optimization tool based on real-time electricity price monitoring. It continuously tracks price fluctuations and automatically adjusts inverter operation for maximum efficiency. Operating 24/7 fully autonomously, the system helps users reduce power costs, maximize energy utilization, and achieve true energy independence — without the need for manual intervention..
