All In One | 10kWh / 20kWh 5kW All-In-One Solar Energy Storage System

Single Phase Hybrid Storage Inverter 4-6 kW Plus Series

The VOLTARIX Low Voltage Series Storage Inverters are engineered to enhance homeowners’ energy independence with advanced storage technology. With a power range from 4 kW to 6 kW, these inverters are fully compatible with low-voltage (40–60 V) batteries. The system’s intelligent energy management utilizes time-of-use and demand charge rate strategies to minimize reliance on the public grid and reduce overall energy costs.

Thanks to the UPS function (switching time < 10 ms), critical household loads remain powered seamlessly during grid outages. In backup mode, the inverter can deliver up to 150% peak output overload, ensuring uninterrupted power for essential devices.

The VOLTARIX Smart Energy Management System introduces Dynamic Electricity Pricing & Automation, which continuously tracks real-time electricity prices and automatically optimizes power usage. Operating 24/7 autonomously, it empowers users to maximize self-consumption, lower electricity bills, and achieve greater energy efficiency — without manual intervention.
