Encyclopedia of Inverter Efficiency Testers

　　Encyclopedia of Inverter Efficiency TestersIt is a specialized equipment designed for accurately measuring the energy conversion efficiency of photovoltaic inverters. It synchronously collects the DC input power and AC output power of the inverter, combines high-precision sensors and intelligent algorithms, calculates the conversion efficiency in real time, and analyzes key indicators such as harmonic distortion and power factor.

1Encyclopedia of Inverter Efficiency TestersProduct Introduction

The product is a photovoltaic module IV curve tester, which can achieve voltage testing up to 1500V, current testing up to 30A, and can test 30kW photovoltaic modules. It can test parameters such as open circuit voltage, short-circuit current, and high power of solar cell modules/arrays, providing users with accurate and efficient volt ampere characteristic testing tools. It can quickly detect the working characteristics of photovoltaic strings under natural light. The equipment is easy to operate, portable, and equipped with high-precision irradiance meters and temperature sensors, which can provide accurate on-site irradiance values and other parameters.

The portable IV tester adopts one-piece packaging technology, with clear operation interface function instructions, one key detection data export, and a single component/string detection speed of 10 seconds. The fast, accurate, and comprehensive detection function can be used as an optional configuration for third-party detection institutions 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 analysis software. It can analyze IV curves more clearly and has the advantage of continuous IV uninterrupted scanning, which helps to detect the entire photovoltaic power plant system.
