The PAX DNA

Our DNA defines how we think, build and deliver.It guides every project, every system design and every interaction ensuring consistent, high-quality outcomes for installers, partners and customers.

This can be easily summarised through six core pillars.

OUR MISSION

PAX Empowers Commercial Battery Installers

At PAX Energy, we exist to make commercial and industrial battery installations simple, reliable and profitable for Australian installers.

C&I projects can be messy unclear designs, mismatched components, slow responses and customers who hesitate because they don’t fully understand the solution. We’re here to remove that friction.

Our team is made up of engineers, not salespeople. Every conversation is grounded in real technical expertise, practical experience and an honest, straightforward approach that helps installers get the job over the line.

We design and deliver battery energy storage systems from 30 kW to 500 kW, and we support every step of the journey - from opportunity qualification and system design, through installation and commissioning, to long-term lifecycle support.

With PAX, you don’t just get a BESS product.

You get a partner who understands the challenges, solves the complexity, and makes commercial battery jobs easier for installers.

WHO WE ARE

Meet the Team

We’re engineers and problem-solvers with a track record that speaks for itself: 35+ years in BESS, 3,000 systems operating in the field, and four battery startups - two of which went all the way to the ASX.
We’ve lived the challenges of commercial storage firsthand, and now we’re building PAX to make C&I energy systems simple for installers.
