Product Introduction
LX-PV33 is a Lexus standard photovoltaic module IV curve tester, which can accurately detect the emission of components and strings within the 2000V range

Electric efficiency and conversion rate, solving the problem of insufficient 1500V20A range in the mainstream market. At the same time, for the working electricity of about 20A for half modules

Flow measurement, expanding the testing range to 40A, can better perform component testing.
The LX-PV33 new solution provides dual glass battery detection function, without the need for back panel obstruction testing. The battery and string level dual sided dual glass

The component can shield the back panel's electrical energy influence through the forward and reverse dual sided multi irradiation algorithm, and only calculate the positive side battery's power generation efficiency and STC conversion value, which is fast
The precise and comprehensive detection function can be used as an optional configuration for third-party detection agencies and power station operation and maintenance

The whole machine is equipped with high-precision capacitive/resistive loads, as well as a faster radiometer operation module and corresponding IV curve division

Analysis software, which can analyze IV curves more clearly and has the advantage of continuous IV uninterrupted scanning, helps to detect the entire photovoltaic power plant system
