Smart, cost-saving load balancing for OCPP multi-charger installs
Why choose the Libra?
Prevents overloads
Balances charger output at the incoming supply so sites don’t exceed safe capacity — avoiding outages and downtime in EV charging networks.
Avoids grid upgrades
Maximises existing supply and enables more chargers without expensive infrastructure expansion, reducing total project costs.
Real-time monitoring
Continuously tracks site power usage and updates the OCPP platform every few seconds for live EV charging load management.
No recurring costs
Includes 3 years of 4G data, firmware, and support with no monthly subscription fees.
The Libra load balancer provides a single, centralised solution for managing site power—maximising capacity without compromising on charging availability. By dynamically distributing load across any OCPP-compatible chargers, Libra allows new chargers to be added without risking supply trips or costly infrastructure upgrades. Want to know more?

FAQs
Libra is hardware-agnostic and pre-integrated with major OCPP 1.6+ platforms. For non-pre-integrated platforms, a one-time integration is required before commissioning.
Yes. Libra is designed for three-phase monitoring but can also support single-phase installations if required, making it versatile for different site conditions.
Libra is offered in several configurations, including CT clamp versions (150A, 400A, 600A) and Rogowski coil models up to 1000A, with bespoke options available for larger installations.
Libra is wall-mounted using the supplied fixings. It requires a 6A 3-phase 5-core 1mm supply and can connect via Wi-Fi, Ethernet (RJ45), or 4G with a SIM card.
Libra comes with 3 years of 4G data, firmware updates, and technical support. After this period, operators can purchase a new licence code to extend services.
No. Libra is designed for indoor environments with non-condensing humidity and should be protected from direct exposure to water or corrosive conditions.
The system includes an “Update Threshold” setting. When power usage remains stable, fewer data packets are sent to the OCPP platform, reducing overall data consumption.
Libra requires only routine checks for visible damage and regular testing of residual current protection. Any internal servicing must be carried out by a qualified Charge-M8 engineer.
