Powerstar Voltage Optimisation

In Australia, electricity supply is not clean, the voltage typically has some level of fluctuation – resulting in electricity being supplied at a higher-than-needed voltage during the spikes. Even though the excess power supply is not used by your machines and appliances, you are still charged for this power. The excess voltage makes equipment run hotter while reducing its life expectancy.

Powerstar’s patented voltage optimisation unit maintains voltage at the optimum level without fluctuation – thereby reducing your energy consumption without compromising on the supply, and reducing your maintenance costs and increase the lifespan of your equipment. Most products in Australia are designed to run at 220V, while power is being supplied at up to 250V. Australian companies stand to benefit from significant savings by implementing voltage optimisation technology.

Voltage Optimisation Applications

Powerstar voltage optimisation units are not off-the-shelf, they can be designed for use in various applications: 

  • Industrial
  • Commerical
  • Small Business
  • Residential

Voltage Optimization Benefits:

  • Powerstar can save you up to 26.1% energy consumption,
  • Reducing carbon emissions
  • Reduces maximum load
  • Significantly reduces harmonics
  • Improves power factor by up to 20%
  • Helps protect against power spikes (of up to 25,000V)
  • Lowers operating temperature of motors
  • Increases life expectancy of equipment and reduces maintenance costs.
  • Provides voltage phase balancing
  • Has no moving parts therefore no maintenance is required.
  • Comes with a 10 year warranty and 50 year life span.

How can we implement PowerStar Voltage Optimisation in Australia?

Powerstar is setup to bring the voltage inline with the actual needs of your onsite equipment. We perform a full site survery to determine your requirements.

How much can I save?

Typically, a 5% reduction in voltage has been shown to create energy savings of at least 10%. On average, Powerstar’s units have been proven to deliver a saving of 12-15% of consumed electricity.

Why Powerstar?

Established in 2001, Powerstar is the only voltage optimisation system in the world with a patented design. Offering a range of  HV (Powerstar HV MAX) and LV (Powerstar & Powerstar MAX) solutions, the global market leading range of power optimisation systems deliver average savings of 12%-15%, and typical returns on investment of 2-3 years.

Powerstar systems are fully manufactured in the UK and are renowned for the their quality, efficiency and reliability.

How we work

The acclaimed project-led approach adopted by Liberty Saver ensures that the team work closely with clients to understand business operations and requirements for each site to ensure maximum savings are achieved through power optimisation.


Guaranteed Energy Savings – Your return on investment is guaranteed

Savings and reduced energy consumption from all Liberty Saver systems are 100% guaranteed, all analysis is based upon IPMVP and is carried out via the steps below

  • Step 1 – Compares 28 days pre install kWh data against 28 days post install kWh data.
  • Step 2 – Compares 28 days post install kWh data against the same dates a year previous (pre install).
  • Step 3 – Compares 84 days (12 weeks) post install kWh data against the same dates a year previous (pre install).
  • Step 4 – This involves a regression analysis. An accurate model is created based upon pre install kWh consumption data and variables such as the temperature.

Following the analysis, if savings achieved are less than stated in the proposal, the shortfall in terms of $ based on p/ kWh used in the proposal will be calculated.
This figure is multiplied by the payback period as stated in the proposal and issued as a one-off payment.

Proposal states 10% saving worth $15,000 pa giving a payback of 2.8 years.

Actual energy savings achieved = 8% worth $12,000

Shortfall = $3,000

We issue a 1 x off payment to the client of $3,000 x 2.8 = $8,400 so the return on investment  is therefore guaranteed.
