This remote panel allows full monitoring and control of your Sterling Pro Charge Ultra battery charger from a convenient location – perfect for mounting at the helm or in the cabin. Featuring a clear LED/LCD display, the panel shows real-time charging voltage, current, the selected battery type, charger/battery temperature, and any error messages. With the included 10-meter cable, you have the flexibility to install it wherever you need for easy viewing. Three mounting options (surface, flush, or semi-flush) let it seamlessly integrate into any dashboard.

• Remote Monitoring: Keep an eye on your battery charging without going below deck – voltage (V) and current (A) are continuously displayed, along with charge status (bulk, absorption, float).
• Full Control: Use the remote to adjust settings such as charging mode or battery profile, activate “night mode” for silent charging, or turn the charger on/off as needed – all from a distance.
• Alarms & Indicators: In case of any issue (overheat, sensor fault, etc.), the panel displays error codes or warnings – enabling you to respond quickly to any charger or battery problems.
• Easy Installation: Panel size is about 110 x 68 mm – compact yet easy to read. A 10 m cable (extendable if necessary) with plug-and-play connectors is included – simply connect it to the charger. The panel can be surface-mounted or flush-mounted for a clean look on your console.
• Added Convenience: Ideal for larger boats and yachts – monitor your battery status from the salon or helm, without needing to access the charger in the engine room every time.
