Specifications Parameter Specification Model VX4A71101Y Series Xantrex VX4 (or similar system monitor series) Display Backlit LCD (Liquid Crystal Display), typically monochrome or with a specific color scheme for status indication. Input Voltage (for meter itself) Designed to be powered directly from the system's 12V or 24V DC battery bank. (May have a wide operating range, e.g., 10-32V DC). Communication Interface Proprietary digital communication bus (likely a dedicated multi-wire cable) to connect and communicate with compatible Xantrex devices (e.g., inverters like the Xantrex Freedom SW series). Monitoring Parameters (Typical)

• Voltage: DC Battery Voltage, AC Output Voltage (via inverter).
• Current: DC Charge/Discharge Current (in Amps).
• Energy: Amp-hours (Ah) consumed or remaining.
• Power: Watts (W) or Kilowatts (kW).
• Status: Inverter/Charger mode (Inverting, Charging, Standby, Search), Fault codes.
• Time: System runtime.

Control Functions (via Keypad)

• Inverter ON/OFF
• Charger Enable/Disable
• Generator Start/Stop (if connected to a generator start module)
• Source Selection (e.g., Shore Power vs. Inverter)
• Menu Navigation for setup

Alarms Visual (on-screen icons/messages, possibly an LED) and audible buzzer for conditions like: Low Battery, Overload, High Temperature, etc. Mounting Panel-mount design. Requires cutting a rectangular hole in the panel/dashboard. Comes with a mounting bezel. Dimensions (Cutout) Specific to model. Example (common for such units): Approximately 122mm x 82mm (4.8" x 3.2") rectangular cutout. Refer to official manual for exact dimensions. Environmental Rating Likely designed for indoor/marine environments. May have a degree of moisture resistance but is not typically fully waterproof (IP rated). Compliance Meets relevant marine (e.g., ABYC) and general electrical safety standards.
