Container-MVar: Container-Enclosed Capacitor & Filter Bank

May 19, 2025

Maintaining power quality is critical for renewables and large-scale industrial operations—to protect equipment lifespan, minimize downtime and maximize efficiency. Installing capacitor and filter banks is the clear solution, offering:

  • Improved power factor
  • Enhanced system capacity
  • Voltage stabilization
  • Harmonics mitigation


But what happens when the site is in a remote environment? Deploying traditional capacitor enclosures can pose logistical challenges. That’s where Powerside’s Container-MVar comes into play.

A fully engineered, medium-voltage, metal-enclosed capacitor bank housed entirely in a standard 20′ or 40′ ISO container. Designed to deliver reactive power support in the field, it arrives assembled with all switching, protection and controls in place — ready to connect with minimal on-site work.

Features & Benefits:

  • Key interlock systems
  • Stage-level overcurrent and voltage protection
  • Harmonic distortion
  • (THDv/THDi) monitoring
  • Arc flash detection and thermal alarms
  • Blown fuse indicators
  • Control power transformer for auxiliary loads
  • Modular and easy to move
  • Fast setup reduces site labor
  • Durable and stackable
  • Easy servicing and maintenance
  • Reduces install costs and timelines
