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 firmware updates, technical support and optional 4G data. 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.
