All 4 steps are completely free of charge and without any obligation and we are happy to visit you Australia wide for a full presentation on Voltage Power Optimisation— including the background of the technology, our simple 4 step process and answer your technical queries.
1. You highest maximum demand in kW or kVA in the last year for each incoming supply to your site
2. Your total kWh consumption for the last year for each incoming supply
3. Your total electricity cost ex GST or cents per kWh rate.
We will email you a provisional cost/value page (below) for your review
showing costs, expected savings, ROI, payback period.
Your voltage logger simply needs to be plugged into a standard 3-pin point for 5 days at the closest point to your incoming supply—then moved to the furthest point from your incoming electrical supply for a further 2 days.
We will send you a graph of your voltage profile (below) with a recommended Optimisation setting - and update your cost/value page. E-Four VPO’s can optimise by -4,-5,-6,-7,-8,-9,-10,-11,-12 % or VPO Deluxe

As every site is different we will need to discuss with your electrical load profile.
With this data we will be able to provide an accurate estimated saving for your site.
When estimating savings we need to consider if your site has energy efficient equipment which can lower the savings such as High Frequency lighting or Variable Speed Drives.

The business case is looking good but only shows an “estimated” installation cost, so our Engineering Department will arrange for either your or one of our preferred electrical contractors to formally survey your site for a “fixed cost quote” for the installation.

Where can we install?
The unit is ideally installed is in your electrical switch room but we can install in an adjacent room or even in a suitable IP rated outdoor enclosure.

After a contractor has visited your site, we are now in a position to submit a final cost / value page and a full business proposal; you can now review the full business proposition with your team.
If, after receipt of the business proposition, you would like us to give your team a full presentation on the E-Four Voltage Power Optimiser to assist in the decision making process we will be pleased to do so. We can also discuss and arrange a leasing agreement.

Your chosen electrical contractor will undertake pre-works prior to installation to keep the shut down time to a minimum. Pre-shutdown preparation time varies with the size of the unit and will take anything from 1hr upwards.
At the agreed time, the electrical contractor will interrupt the supply to the site and install the E-Four VPO as quickly as possible. 30 mins to 5 hours downtime is normal and mobile generation can be provided for critical sites.
We take full responsibility for the work of all our contractors, our Engineering Department ensure all electrical work completed by our contractors is of the highest quality.
