Intelligent energy management for campsites
The campsite sector faces unique challenges in low-voltage electrical distribution, demanding solutions that combine flexibility, reliability, and intelligent control.

A recent implementation project – developed through close collaboration with a specialized systems integrator – successfully demonstrated how cutting-edge technologies can revolutionize energy management. By deploying advanced monitoring and control systems, the solution achieves optimal resource utilization while maintaining robust operational reliability, setting a new standard for efficient power distribution in outdoor hospitality environments.
The project was initiated to address the critical need for detailed power consumption analysis and optimization in the campsite environment, which presented unique technical challenges. One of these was the requirement to reset individual pitch energy meters automatically during guest check-outs for precise billing and transparent energy reporting. Other challenges included the implementation of a centralized management system capable of communicating with existing infrastructure without costly underground cable installations, and intelligent load shedding during peak consumption periods to maintain grid stability – all whilst ensuring that the solution could provide comprehensive monitoring and control through seamless integration with existing management software using standard protocols like Modbus RS485.
The optimal solution to these requirements was achieved through the implementation of the OPTA Advanced system, which combines Wi-Fi connectivity and Modbus RS485 protocol. OPTA’s versatility made it the ideal choice, enabling seamless integration with existing energy management software whilst being rugged enough for both industrial and outdoor applications. The wireless capability proved particularly valuable by eliminating the need for underground cabling, resulting in significant cost savings and faster deployment.
To expand system functionality, Type 8A.58 EMR expansion modules were incorporated, adding 16 digital/analog inputs and 8 EMR relay outputs – critical for managing multiple power sockets per distribution column (typically 4-6 units) whilst handling signalling and alarm functions. For precise energy monitoring, the system utilized Finder’s MID-certified 7M Series energy meters: the single-phase 7M.24 and three-phase bi-directional 7M.38, both featuring Modbus RS485 interfaces for real-time consumption data transmission to the OPTA system and subsequent management platforms. This comprehensive solution ensured accurate kWh measurement whilst maintaining full compliance with metering standards.
