Getting Started

To build your SRNE smart power system, start with the RMA7 Touch Screen Display and the CU2 Data Management System — the heart of the SRNE ecosystem.

The CU2 Control Centre integrates seamlessly with your SRNE components and comes equipped with built-in Bluetooth and Wi-Fi connectivity, allowing you to monitor and control your system through the SRNE App or directly from the RMA7 touchscreen.

With six 6A relay outputs, the CU2 can control lighting, fans, and other onboard devices at the touch of a button. It also supports water level and temperature sensors, giving you full visibility of your vehicle or off-grid setup.

For complete power management, add the BS48500 Battery Shunt to connect your leisure battery to the CU2, enabling accurate monitoring of battery status, current draw, and energy usage — all viewable on the RMA7 or through the app.

Together, these components form the foundation of a smart, connected RV or off-grid power system designed for comfort, control, and reliability.
