The SRNE SR-RM-5 is a compact remote LCD monitoring unit designed for use with SRNE solar charge controllers, providing real-time system data, fault diagnostics, and controller management from a convenient wall or panel-mounted display.

Key Features

• 128x64 Graphical LCD Display Main menu displays up to 10 parameters and system states simultaneously in a combined numeric and graphical format, with adjustable backlight timer for low-power operation.
• Historical Data Logging Records and retrieves historical charging and discharging capacity data by day, enabling performance review and energy auditing without an external device.
• BLE 4.0 Wireless Connectivity Optional low-power Bluetooth 4.0 pairing with a mobile app expands monitoring and control capabilities beyond what the local display provides.
• Dual Indicator Lights Separate LED indicators for controller abnormalities and communication errors provide instant visual status at a glance, supplemented by an optional voice alarm for fault conditions.
• Controller-Powered via RJ12 Draws power directly from the connected controller through the standard RJ12 6-pin data cable with no external power supply required, simplifying installation significantly.

The SR-RM-5 communicates via standard Modbus protocol over RS232 at 9600 baud through a standard RJ12 interface, and displays PV voltage, battery voltage, charge current, load current, charge and discharge capacity, temperature, and fault codes E0 through E9. On-device controls allow on/off switching, clearing of historical data, factory reset, and auto-browsing mode activation directly from the front panel buttons.

Built to industrial-grade standards with strong anti-interference capacity, the SR-RM-5 mounts to a controller enclosure, panel cutout, or wall back-box using standard 50x50mm or 70x70mm installation dimensions. Standby power consumption is below 35mA at 12V with backlight on and below 25mA with backlight off, making it suitable for always-on monitoring installations.
