Compared to other VO systems, Powerstar© MAX dynamically adjusts the voltage supplied to your site in real time, ensuring your equipment operates at peak efficiency to help your business minimise energy waste.
Leading the market since 2001
Powerstar has been a leader in the voltage optimisation market for 24 years and is trusted by some of the UK’s most renowned businesses.
Real-time online monitoring
Track and visualise your savings through our online portal, empowering you to make informed decisions about energy consumption and financial savings.
Bypass protection
Powerstar© MAX units come with bypass protection as standard, ensuring that in the unlikely event of a unit failure, your facility will not lose power.
British manufacturing excellence
We’re commitment to quality and local manufacturing. Our state-of-the-art facility manages every stage of production, prioritising local sourcing and component traceability.
Installation at your convenience
Powerstar’s engineers and accredited installers will work with you to schedule the installation at your convenience – we can even take care of the DNO if required.
Accelerate your Net Zero journey
Our voltage optimisation technology is proven to reduce energy consumption and CO2 emissions, helping your business achieve its decarbonisation goals and drive the transition to net zero.
Discounts on government schemes
Contribute to schemes such as the Climate Change Agreement (CCA), which reduces the Climate Change Levy (CCL) and offers discounts of up to 95%.
Cost savings
Cut energy bills by up to 6-9%, with an average return on investment typically achieved within 12-30 months, enabling your business to offset rising energy costs and stay competitive.
Stabilise voltage
Our Powerstar MAX systems regulate and stabilise your site voltage to address frequency and voltage fluctuations caused by grid instability and intermittent renewable sources – such as solar and wind.
Overcome grid constraints
Voltage optimisation can be implemented without complex grid connection approvals, bypassing lengthy delays and allowing businesses to improve energy efficiency and reliability immediately.
Voltage Optimisation: Your Path to Smarter Energy
1. Project Discussion
Get in touch with our team or complete the form below to help us understand your requirements. We’ll then assess the potential for savings and provide indicative ROI based on site specifics.
2. Site Survey
Our Powerstar experts will then conduct a site survey to scope installation requirements and costs, alongside a detailed voltage log to understand your site’s profile.
3. Final Proposal Provided
We’ll send you a comprehensive proposal with an overview of projected kWh and CO2 savings.
4. Installation and Commissioning
Once approved, Powerstar’s accredited installers will deliver and install the unit according to the agreed schedule. We’ll then commission the unit, ensuring it is fully operational and seamlessly integrated with the existing infrastructure.
5. Aftercare and Monitoring
Our aftercare team will provide training on our online portal and conduct ongoing monitoring and support to ensure the system is delivering the expected benefits.
