Commercial Batteries Without the Complexity.
Make C&I installs as easy as residential.
THE PAX VISION
We’re Here to Fix the Problems That Hold Installers Back in C&I
Most commercial battery jobs fall apart early - unclear designs, incomplete documentation, mismatched components and customers who lose confidence before signing.
And when those problems appear, installers are the ones left carrying the burden. PAX eliminates these issues by leading with engineering from day one.
We help you qualify the opportunity properly, design the system correctly, and present a solution that gives your customers confidence to go ahead.
Every part of our approach exists to remove installer headaches - so you can quote faster, win more jobs, and complete projects without surprises.

THE PAX INCLUSIONS THAT HELP
YOU GET THE JOB OVER THE LINE
Why is PAX engineering support free?
Because charging for engineering creates the wrong incentives.
At PAX, engineering support is free because it’s essential to system performance - not an optional extra.
We support installers with proper system design, documentation, and technical guidance, reducing risk and complexity on site.
We give end customers confidence that their system has been engineered correctly from day one.
Free engineering support means better systems, smoother installs, and long-term performance for everyone involved.
