Kiwigrid Home Energy Management System RailX

The RailX Energy Manager from Kiwigrid (MPN: RailX) is a professional, space-saving solution for DIN rail mounting and, thanks to its compact design, fits into any control cabinet. The gateway allows for the easy, manufacturer-agnostic integration and control of PV/hybrid inverters, energy storage systems, charging stations, heat pumps, and smart meters, enabling optimal, cross-sector energy utilization. Devices are automatically detected; configuration is intuitive via Smart Setup, and remote configuration is also straightforward. The integrated Bluetooth interface allows for easy installation via smartphone. Smart switches such as Shelly can be integrated via Ethernet or Wi-Fi, simplifying the control of electrical loads.

Highlights of the Energy Manager

• 4-core processor— The gateway is as powerful as a modern smartphone, making it ideally suited for future applications in the Energy IoT (Internet of Things)
• High processing power— High performance and modern OSGI architecture enable parallel execution of applications, ensuring maximum use-case flexibility
• Energy Cost Optimization – By integrating dynamic electricity rates and strategically controlling large appliances, you can reduce your energy costs.
• Transparency Across All Devices – Inverters, heat pumps, battery storage systems, and wallboxes are seamlessly integrated. All data is clearly displayed.
• Smart Control – Set up custom control schedules for your devices and receive forecasts for optimal operation.
• Automatic maximization of self-consumption— Get the most out of your PV system. Storage systems and electric vehicles are charged intelligently.
• High level of security— featuring state-of-the-art methods for encrypting data transmission and authenticating users and devices

What is a Home Energy Management System?

A home energy management system (HEMS) in combination with the RailX Energy Manager is a smart solution that lets you centrally control and monitor all major energy-consuming devices in your home, such as your solar system, battery storage, heat pump, and electric vehicle charging station. The gateway connects these devices regardless of the manufacturer, collects all energy data in one place, and ensures that electricity is used optimally. This allows you to save energy, reduce costs, and easily manage your devices via the app or remotely.
