1. Hydrostatic Pressure Testing
- Rigorous hydrostatic pressure tests – exposed to high water pressure in controlled lab environments.
- Confirms hydrophobic membrane completely prevents liquid water penetration.
- Maintains watertight seal during severe rainstorms or high‑pressure water jetting.
2. Airflow & Breathability Measurement
- Specialized airflow measurement equipment – evaluates air permeability and flow rates under pressure differentials.
- Ensures adequate breathability for pressure equalization.
- Guarantees release of expanding gases and prevents pressure buildup.
3. Environmental Weathering Simulations
- Accelerated aging tests in climate chambers – extreme temperatures, UV radiation, and salt spray.
- Predicts long‑term material performance over years of outdoor exposure.
- Ensures waterproof and breathable properties do not degrade prematurely.
4. Integrated System Leak Detection
- Tested as part of complete inverter assembly – verifies overall system integrity.
- Evaluates sealing gasket compression against enclosure.
- Confirms no moisture or dust can bypass the venting component.
