What is power factor correction, and do I need it?

Power factor correction (PFC) improves the efficiency of your electrical system by reducing the amount of wasted reactive power. Businesses with large electrical loads—such as HVAC systems, motors, or industrial equipment—often benefit from PFC. It can lower your energy costs, improve equipment lifespan, help with phase balancing and help ensure compliance with energy regulations. We supply and install Static Var Generator power factor correction units for commercial and industrial clients across Melbourne, and can provide maintenance services for the older style capacitor banks.

Do you handle industrial electrical services?

Absolutely. Whilst we specialise in Power quality, we provide a full suite of industrial electrical services including machinery installations, motor control systems, automation, fault finding, maintenance programs, and safety upgrades. Our team understands the demands of industrial environments and delivers durable, compliant solutions that keep factories and facilities operating at peak performance.

Can you support solar installations and grid connected systems?

Yes—our electricians are trained in both solar and batteries, grid connected and off grid. We offer solar system installation, repairs, inverter replacements, grid connection support, monitoring services, and ongoing maintenance. Whether you need a commercial or high end residential solar for cost reduction or a hybrid system for improved reliability, we provide solutions tailored to your site’s energy requirements.

Do you offer 24/7 emergency electrical service?

We provide 24/7 emergency electrical support throughout Melbourne for breakdowns, power outages, safety hazards, equipment failures, and urgent repairs. Our rapid-response electricians arrive with the tools and expertise needed to restore power safely and minimise downtime, whether it’s a commercial site, construction project, or industrial facility.
