CBI :energy’s Managed Smart Metering system reduces your electricity bills by making you and your building smarter, providing you with the real-time information you need to manage your operations better. A combination of connected smart meters, powerful software and advanced analytics transforms detailed, real-time data into decision-ready insights.
The most capable, cost-effective and compact energy metering solution on the market today that provides both business and technical audiences with detailed visibility into their energy generation, usage and costs. Information is accessed via a variety of interfaces, dashboards and reporting capabilities, or get hold of your own live, detailed data via the open API to use existing management systems.
Fast and easy installation: “Fit & Form” compact bulk energy meters can be deployed with minimal disruption to business operations; an easy retro-fit that needs no changes to electrical or building infrastructure.
Detailed billing-grade telemetry at one minute intervals: Power, Energy, Voltage, Current, Power Factor and Device Temperature, plus diagnostic metadata.
Standards compliant, quality hardware to monitor and meter up to 80A in-line or use an external CT for larger loads (ratio configurable).
Highly resilient fully managed energy metering and monitoring solution specifically designed for medium to large commercial implementation with powerful Cloud-based management and monitoring dashboards.
Receive notifications by email, SMS or push about generation and consumption activity via user-configured, centrally-managed rules, policies, dashboards and reports.
Detailed visibility on actual and potential energy and cost savings via an intelligent rating and billing system, with configurable business-focused benchmarks.
Wirelessly connected metering devices communicate via corporate or IoT-dedicated Wi-Fi network.
Automatically generate source data and reports for the for ‘Green Certification’ such as building Energy Performance Certificates (EPCs) and ISO 50000 certification.
Data-driven decision making from detailed energy telemetry and analytics to change behaviour and drive sustainable energy efficiency and energy saving initiatives.
