Low temperature will bring changes in physical properties of electronic components, and this change tends to be in an unfavorable direction. Blizzard has a great impact on photovoltaic power stations. Too thick snow will lead to over icing of components, affecting the power generation and life of the system, resulting in a decline in power generation and even stop work. For solar inverter, it is a severe test. Cold climate conditions may make the inverter can not work steadily, such as can not start, frequent alarm, power generation reduction and other problems.
How to choose inverter to deal with the erosion of extreme weather?
1.Select components of wide range of working temperature to fully meet the low temperature service conditions.
2.Takes full account of the demand for low temperature work in the design of the product, leaving enough margin (including capacity margin and time margin).
3.The product should be tested for a long time at low temperature to ensure the validation of theoretical value.
How to do the inspection of the outdoor inverter well?
After long time use, there will be aging phenomenon in the connection of inverter.The inverter has its own insulation impedance detection, which can reliably protect the inverter. At the same time, it needs to pass the on-site inspection, and the thermal imager can scan the connection points of each cable at work; Check whether the inverter PV input terminal is stable or loose; Whether the AC terminal is aging and loosening; Whether there is grounding in the PV line under the sun plate.
