Merus Power, Solutions for Power Quality.
Enabling a Sustainable and Energy-efficient future
Modern electrical systems rely heavily on electronic devices such as variable frequency drives, UPS systems, LED lighting, and inverters.
While these technologies improve control and efficiency, they also generate harmonics — unwanted electrical distortions that can harm your power system.
Over time, harmonics can lead to:
- Overheating of cables, transformers, and motors
- Reduced efficiency and higher energy losses
- Equipment malfunction or premature failure
- Nuisance tripping of protective devices
- Power factor penalties and increased operating costs
A harmonic filter helps eliminate these distortions, restoring your electrical system to clean, stable, and balanced power by maintaining power quality, harmonic filters improve efficiency, protect equipment, and ensure reliable operation across your entire facility.

Merus® A2-Active Harmonic Filters
operate similarly to noise-canceling headphones.
Merus® ESS is not just a battery. It is a high-power, fast-reacting, and reliable lithium-ion-based battery energy storage system fully designed and manufactured by Merus Power.

Merus® HPQ is an all-in-one power quality system for combined active harmonic mitigation and power factor correction.
- A hybrid power quality compensator that combines two existing technologies in one compact and well-performing solution.
- Operation is based on two main components: a detuned capacitor bank and an active harmonic filter. The detuned capacitor steps fulfill most capacitive reactive power needs.
- An all-in-one power quality system.
