The Projecta Intelli-Jay PM100-BTJ is a 12V power management system designed for use in caravans and motor homes, offering a comprehensive solution for charging and managing various battery types. This system is engineered for ease of installation and features a user-friendly interface, eliminating the need for complex cable harnesses.
The core function of the PM100-BTJ is smart battery charging and power management. It acts as a multi-chemistry battery charger, capable of charging 12V 30A lead-acid batteries (AGM, GEL, WET) and lithium (LiFePO4) batteries. The system incorporates a 5-step charging algorithm: soft start, bulk, absorption, float, and recycle. This microprocessor-controlled algorithm ensures optimal charging for batteries in different states, maximizing battery life and maintaining a 100% charge over extended periods.
Beyond charging, the PM100-BTJ also functions as a 35A power supply, automatically switching between power supply and charging modes to provide a static 12.8VDC output for DC loads. It includes a Voltage Charging Relay (VCR), also known as a Voltage Sensitive Relay (VSR), which allows the house battery to be charged by the alternator when the vehicle engine is running. The VCR activates when the vehicle battery reaches a specific voltage (13.4VDC for lead acid or 13.7VDC for lithium) and continues charging until the vehicle battery voltage drops below 12.8VDC (lead acid) or 13.3VDC (lithium). It's important to note that when charging from the vehicle battery, the system does not provide the full 5-stage charge but rather utilizes available power from the alternator.
The system features Battery Low Voltage Protection (BLVP), also known as Low Voltage Disconnect (LVD), which automatically disconnects loads when the house battery voltage drops below a preset threshold (10.5VDC for lead acid or 11.2VDC for lithium) after a 60-second delay. This protects the battery from deep discharge.
The PM100-BTJ offers multiple charging inputs, primarily from AC mains and the vehicle battery. It prioritizes AC mains when available. The unit also provides 10 fused DC outputs (2 x 15A, 8 x 10A) for various loads. A thermal-controlled fan ensures efficient cooling, and the system includes water level monitoring for up to two tanks plus a waste tank, providing comprehensive oversight of essential RV utilities.
The PM100-BTJ is designed for intuitive operation, enhanced by its Bluetooth connectivity and a dedicated remote app.
Connectivity and App Control: The system integrates a PMBTJ-02 Bluetooth Node, allowing users to connect their smart devices (iPhone/iPad or Android) via the "IntelliJay PM100-BTJ" app. After downloading the app and ensuring Bluetooth is enabled, users can pair their device using the last four digits of the Bluetooth node's serial number as the default pairing code.
The app serves as a central hub for monitoring and control. From the home screen, users can view:
Battery Type Selection: A crucial feature accessible via the app is the ability to select the battery type (AGM, GEL, LFP, or WET). This ensures the charging algorithm is optimized for the specific battery chemistry, promoting battery health and longevity.
Output Power Isolation (Load Switch): The system includes a load switch that can turn off power to most DC outputs (except +L1, which is always ON). This feature is useful for reducing power consumption, especially when the vehicle is in storage. If AC Mains are not connected, activating the load switch also cuts power to the Bluetooth module, placing the system in "Storage Mode."
LED Diagnostic Codes: The PM100-BTJ features a set of LED indicators on its front panel for quick visual diagnostics. These LEDs indicate the status of the mains connection, vehicle battery, charging process, and any faults. Different colors (Green, Red) and flashing patterns (illuminating, dim, flash, slow flash, quick flash) convey specific information, such as:
Firmware Updates: The app also supports firmware updates for the PM100-BTJ system, ensuring it remains up-to-date with the latest features and improvements. Users are advised to stay in close proximity to the system and avoid disconnecting power during updates.
The PM100-BTJ is designed with several features that contribute to its reliability and ease of maintenance:
Overload Protection: The system incorporates overload protection for its fused DC outputs, safeguarding connected devices and the unit itself from excessive current draws.
Thermal Management: A thermal-controlled fan helps manage the internal temperature of the unit, preventing overheating during operation. In case of over-temperature conditions (heatsink or environment), the system will trigger a fault indication and may automatically shut down or restart to protect components.
Battery Protection: The BLVP (Low Voltage Disconnect) feature is a key maintenance aspect, preventing deep discharge of the house battery, which can significantly extend its lifespan. The smart 5-stage charging algorithm also contributes to battery health by preventing overcharging and ensuring optimal charge cycles.
Fault Indication and Troubleshooting: The detailed LED diagnostic codes provide immediate visual feedback on the system's status and any potential issues. The manual includes a comprehensive troubleshooting guide that correlates LED patterns with specific problems and offers solutions. For example, if a "House battery low voltage alarm" is indicated, the solution is to charge the house battery as soon as possible. For over-temperature alarms, users are advised to check ventilation and disconnect less priority loads. If faults persist, contacting Projecta support or an installer is recommended.
Cable Management Recommendations: The manual provides guidelines for DC cable sizing to ensure proper current flow and minimize voltage drop, which is crucial for system performance and longevity. It also recommends protecting wires from damage by sharp edges when running them through panels or walls, suggesting additional cable insulation or tubing.
Storage Mode: For long-term storage without power, the system advises turning off the POWER SWITCH or disconnecting all cabling from the battery. This helps preserve the battery and the system's components during periods of inactivity.
Overall, the Projecta Intelli-Jay PM100-BTJ offers a robust and user-friendly power management solution for recreational vehicles, combining advanced charging capabilities with smart monitoring and protective features.
