The UNI-T UT673E is a professional digital solar panel tester designed to evaluate and troubleshoot photovoltaic (PV) systems [Source]. It is primarily used to identify panel abnormalities by instantly measuring parameters like maximum power (\(P_{max}\)), open-circuit voltage (\(Voc\)), and short-circuit current (\(Isc\))
Key Specifications & Features
Maximum Power Range: 60W – 2000W (with 0.1W resolution) [Source]
Voltage & Current: Tests up to 150V and 45A [Source]
Auto MPPT Scan: Automatically tracks and identifies the Maximum Power Point to evaluate peak panel efficiency [Source]
Safety Protections: Built-in reverse polarity protection and internal over-temperature protection [Source]
Power Source: Uses 3 AAA batteries and features an auto power-off function to save battery
