Environmental adaptability of solar on grid inverter

Environmental adaptability refers to the ability of a product to achieve all its intended functions, performance and non-destructive ability under the action of various environments it may encounter in its life cycle prediction. It is an important quality characteristic. It can be seen that environmental adaptability has two elements, one is product and the other is environment. The same product has different environmental adaptability in different environments, and different products have different environmental adaptability in the same environment. Environmental adaptability is one of the quality characteristics of equipment. Once the product is finalized, the materials, components, structural composition and selected process have been solidified, and the environmental adaptability for the given environmental profile is fixed. It can be seen that environmental adaptability is the inherent quality characteristics of products, determined by design and manufacturing, and guaranteed by testing and management.

Generally speaking, the factors that affect product environmental adaptability are as follows.
1.Environmental adaptability of the selected materials and components.
2.The level of structural design includes thermal design, anti vibration, impact protection, corrosion prevention, PCB layout and other design levels.
3.The manufacturing level includes the technological level of structural parts, components, components and veneer protection.

Solar power generation system is usually directly exposed to the outdoor environment, often encounter high temperature, cold, humidity, wind and sand, rain, salt fog and other adverse weather conditions, solar on grid inverter as the key equipment of the whole solar power system, undertake the important role of current conversion, system communication, fault diagnosis and protection. Solar on grid inverter must be able to adapt to different operating environment, especially in harsh environment can still work stably.

Temperature challenges faced by PV grid-connected inverter mainly come from diurnal temperature difference, seasonal temperature difference, weather changes and self-heating. In many northern areas, the temperature is below – 20℃ in winter, over 40℃ in summer, big temperature difference between day and night, big seasonal temperature difference, inconsistent temperature change between the inverter shell and the internal temperature, easy to form temperature difference in the internal cavity, frequent temperature changes, product design, component selection are a serious challenge. The inverter running in wet environment such as coastal and beach will also face the risk of corrosion.
