Industrial Inverter — 3-Phase AC from DC

An Industrial Inverter converts DC power (from batteries or DC bus) into stable 3-phase AC power for industrial loads. Q Sine industrial inverters deliver pure sine wave output with low THD, suitable for integration with battery backup systems and critical manufacturing processes.

Industrial Inverter - Q Sine Energy

The Q Sine Industrial Three-Phase Inverter (10–50 kVA) is designed to deliver reliable, uninterrupted power for mission-critical industrial and commercial applications. Built with advanced IGBT-based inverter technology, the system ensures stable output, high efficiency, and seamless transition during power interruptions.

With near-unity power factor charging, low harmonic distortion, and complete galvanic isolation between mains, battery, and load, the inverter guarantees clean and dependable power supply. Its rugged design and intelligent monitoring capabilities make it ideal for environments where power continuity is essential.

This inverter supports a wide range of battery technologies and offers fast transfer time, ensuring zero disruption to critical operations such as manufacturing lines, data centers, hospitals, and critical lighting systems.

Our Clients

What Our Valued Client Say About Us

For our pharma manufacturing unit, Q Sine implemented hybrid solution which gave us desired savings.

With the installation of 2 x 600 A Active Harmonic Filters the harmonics level has been reduced to less than 3% complying to IEEE 519:2014 and now we are having stable PF. Thank you Q Sine.

We were looking for savings by addressing harmonics related issues and Q SINE installed latest technology of 3 level Active Harmonic Filters at our plant. We are very happy achieving our savings goal in one Sugar season. Also, Our maintenance team have reported lesser failures.

Every textile industry faces acute harmonics issues. Q SINE installed 2550A AHF to mitigate our Harmonics issues and compliance to IEEE 519:2014. Now our operations suffer lesser interruption.
