LD673PV Photovoltaic Module Maximum Power Tester The LD673PV is an advanced, efficient tool designed to accurately measure the maximum power tracking point (MPPT) of photovoltaic panels. This device ensures precise evaluation of key performance indicators, enabling users to assess panel efficiency and diagnose issues quickly and reliably. Key Features and Benefits: Measures critical PV parameters in one operation: Maximum Power (Pmax), Open Circuit Voltage (Voc), and ShortCircuit Current (Isc) displayed simultaneously on a single interface. Enables fast detection of the MPPT, the most important factor in identifying low generation efficiency in photovoltaic systems. Essential for both routine performance assessment and indepth troubleshooting of faulty modules. Large, clear 3.2inch display for easy parameter reading, even in varied lighting conditions. Flexible operation with manual or automatic range selection. Builtin beeper, backlight, low battery indicator, and data hold function for convenience in field work. Automatic shutdown conserves battery life during periods of inactivity. Reverse input protection ensures safe operation. Specifications: Maximum Power: 1000 W Maximum Voltage Range: 12 to 80 V Maximum Current: 35 A Open Circuit Voltage: 12 to 80 V ShortCircuit Current: 35 A Applications: 1. Production and quality control — Reliable for manufacturing lines to verify photovoltaic panel performance before shipment. 2. Installation and acceptance testing — Confirms that newly installed panels operate at expected efficiency before commissioning. 3. Maintenance and troubleshooting — Quickly identifies performance drops or electrical faults, aiding in fast resolution of issues. Compatibility and Use: The LD673PV is suitable for testing a wide range of photovoltaic modules used in residential, commercial, and industrial applications. Its durable design and userfriendly interface make it ideal for technicians, installers, and engineers requiring precise, onsite performance measurements. With its combination of precision, ease of use, and robust safety features, the LD673PV is a trusted solution for ensuring photovoltaic panel performance across all stages of their life cycle.
