Libra Load Balancer – Dynamic Control, Maximum Efficiency
Precise, scalable, and perfect for multi-charger setups
How does it work?
It’s full of clever tech — but getting your head around it doesn’t need a degree. Tap the numbers to see how it all works.
The Libra Dynamic Load Balancer is an advanced solution for intelligent power management.
Libra is designed to monitor a building’s power usage in real time, continuously assessing available capacity across the site.
It communicates with the cloud to intelligently adjust power allocation to connected chargers, ensuring optimal energy use while preventing overload — all without the need for costly grid upgrades.
Whether it’s a commercial car park, workplace, or residential development, Libra enables the installation of more EV chargers without exceeding existing supply limits. With its plug-and-play design and seamless system integration, Libra delivers reliable, efficient, and future-ready charging performance.
