Overview

The SENHOT photovoltaic module PID tester ST-PID meets the testing requirements of IEC61215-2 MQT21 and IEC62804. It can be selected to output channels such as 4/8/12/16 according to actual testing needs, and can provide simultaneous testing of multiple components.

Product Details

ST-PIDPhotovoltaic module PID testing system

Solar energy is an inexhaustible and pollution-free source of energy, and it is also an ideal new energy model. Crystalline silicon photovoltaic modules are a type of outdoor installation that requiresA power generation device that generates electricity by fully receiving solar radiation. Due to various environmental factors, components are inevitably subjected to dust, salt spray, strong winds, rain and snow during useThe reliability assessment of photovoltaic modules is particularly focused on factors such as hail, humidity, dryness, and evaporation of water vapor, atmospheric gas pollution, and temperature changes throughout the four seasons of spring, summer, autumn, and winterThe issues of concern. The potential induced decay test (PID) is also one of them.

PID testing for potential induced degradation.

The component operates at high voltage for a long time, resulting in leakage current between the cover glass, packaging material, and frame. A large amount of charge accumulates on the surface of the battery cell, causing passivation effect on the surface of the battery cellDeterioration leads to a decrease in filling factor, short-circuit current, and open circuit voltage, resulting in component performance below design standards; The purpose of PID testing is to verify that the component can withstand high-intensity voltage performance changesAbility to transform. The PID testing system launched by Shengheda Electronics (Suzhou) Co., Ltd. meets the standard IEC61215-2 MQT21, which is simple, efficient, convenient and flexible to use, and has great advantagesConduct PID testing experiments for users.

SENHOT/HuakeCharacteristics of ST-PID testing system:

1. Meet the standard IEC61215-2 MQT21

2. Multi channel output, can freely choose and match the number of output channels according to actual needs

3. Each channel voltage can be independently set for output and polarity can be independently set

4. The channel is truly independent, and if one channel fails, it will not affect the operation of other channels

5. The voltage setting range can be continuously set from -2000V to+2000V, and other specifications of output voltage can be customized and selected

6. Leakage current alarm setting from 0-500 μ A

7. Can monitor the temperature and humidity of the environmental test chamber (communication instructions for the test chamber need to be provided)

8. The testing time can be freely set according to actual needs
