PV Inverter Sand Dust Test Solution
The PV inverter is a key component in a PV power generation system, responsible for converting the DC power generated by the solar panels into AC power. Since PV inverters are usually installed in outdoor environments, such as deserts, industrial areas or agricultural regions, and are susceptible to sand and dust, it is crucial to conduct sand and dust testing to ensure their reliability and stability in harsh environments. The following are sand and dust testing solutions for PV inverters:
1. Test Purpose
- Evaluate protection performance:
Evaluate the dust protection performance of PV inverters in sand and dust environments to ensure that their internal electronic components are not subject to sand and dust intrusion, which can affect their conversion efficiency and lifetime.
- Verify durability:
To verify the durability and reliability of PV inverters in long-term exposure to sand and dust environments, and to ensure that they can operate stably throughout their life cycle.
- Ensure Safety:
Ensure the electrical safety performance of PV inverters in sand and dust environments to avoid short circuits, overheating, or other safety hazards caused by sand and dust intrusion.
2. Test standards
- IEC 60529:
International Electrotechnical Commission's test standard for enclosure protection level, which specifies the dustproof test methods for IP5X and IP6X.
- IEC 62109-1:
International Electrotechnical Commission standard for safety of PV inverters, containing requirements for environmental testing.
- IEC 60068-2-68:
International Electrotechnical Commission standard on environmental testing with specific methods for sand and dust testing.
- GB/T 2423.37:
Chinese national standard that specifies the method of sand and dust test in the environmental test of electrical and electronic products.
- UL 1741:
Underwriters Laboratories' safety standard for photovoltaic inverters, containing requirements for environmental testing.
3. Test equipment
-
Sand and Dust Test Chamber:
A professional sand and dust test chamber is used, which can accurately control parameters such as sand and dust concentration, airflow rate and temperature and humidity. The test chamber should have the following characteristics:
High precision control:
Able to accurately control the sand dust concentration (usually between 2g/m and 4g) and airflow velocity (usually between 0.5m/s and 10m/s).
Temperature and humidity control:
Can simulate sanding environments under different temperature (-40C to +85C) and humidity (10%RH to 98%RH) conditions.
Stainless steel inner liner:
Adopts stainless steel inner liner, easy to clean and maintain, avoiding the corrosion of the equipment by sanding dust.
- Sanding Dust Generator:
Use high quality sanding dust generating device to ensure even distribution and stable supply of sanding dust.
- Electrical performance testing instruments:
Including insulation resistance tester, voltage withstand tester, grounding resistance tester, etc., used to test the electrical performance of PV inverters in sand and dust environment.
4. test steps
1.
Initial testing:
Under the standard environmental conditions, the PV inverter is initially tested for appearance, basic functions, and electrical performance.
2.
Sample Placement:
Place the PV inverter in the sand and dust test chamber to ensure that it is in normal working condition.
3.
Setting parameters:
Set parameters such as sand and dust concentration, airflow speed, temperature, humidity, test time, etc. according to test standards or customer requirements.
4.
Start test:
Start the sand and dust test chamber, start sand and dust test. The test time is usually a few hours to dozens of hours, the specific time is determined according to the test standard.
5.
Continuous monitoring:
During the test, regularly monitor the performance and status of the PV inverter and record the relevant data.
6.
Electrical performance test:
At the end of the sand and dust test, conduct electrical performance tests, including insulation resistance, withstand voltage, grounding resistance, etc.
7.
Appearance and function check:
At the end of the test, take out the PV inverter and carry out appearance inspection and function test to evaluate its dustproof performance and electrical performance.
5. Assessment Criteria
- Appearance inspection:
Check whether there is any sand and dust deposition on the surface of the PV inverter, and whether there is any sand and dust entry in the sealing part.
- Functional test:
Test whether the functions of the PV inverter are normal and whether they are affected by sand and dust.
- Sealing test:
Evaluate the sealing performance of the PV inverter to ensure that sand and dust will not enter the interior and affect its normal operation.
- Electrical performance test:
Test whether the electrical performance of the PV inverter is affected, such as insulation resistance, withstand voltage, grounding resistance, etc.
- Safety assessment:
Ensure the electrical safety performance of the PV inverter in the sand and dust environment, to avoid short-circuiting, overheating and other safety hazards caused by the intrusion of sand and dust.
6. Application Scenarios
- Outdoor PV power plant:
It is used to evaluate the dustproof performance and reliability of PV inverters in outdoor environments such as deserts, farmlands, industrial areas, etc.
- Building Integrated Photovoltaic (BIPV):
Used to test the performance of inverters in building-integrated PV systems in sand and dust environments.
- Portable PV Equipment:
Used to test the durability and safety of inverters in portable PV equipment in sand and dust environments.
