How does the on grid off grid hybrid inverter guarantee the normal operation of the photovoltaic power plant under cold conditions
In the past 2017, there was less snow in our country, in addition to snow in the northeast and the northwest part of China, the amount of snow in other parts of the region is less. However, the
weather situation had changed greatly at the beginning of the 2018. The Middle East of our country will have the largest and strongest rain and snow weather.
Low temperature will bring about changes in the physical properties of electronic components, and this change tends to develop in a disadvantageous direction. Blizzard has great impact on photovoltaic power station. Too thick snow will cause excessive icing of components, affect the power generation and life of the system, resulting in the decline of power generation and even stop work. For hybrid off grid solar inverter, it is also a severe test. Severe cold climate conditions may make on grid off grid hybrid inverter work unstably, such as failure to start, frequent alarm, low power generation and so on.
How to choose hybrid off grid inverter to cope with extreme weather erosion?
Select the wide working temperature range components to fully meet the conditions of low temperature use.
The product design takes full account of the demand for low temperature work, and has sufficient margin (including capacity margin and time margin).
The product has been tested at low temperature for a long time to ensure the verification of the theoretical value.
How to do the inspection of the outdoor inverter well?
After long time use, the connection of inverter will appear aging phenomenon. The hybrid off grid solar inverter itself has insulation impedance detection, which can reliably protect the hybrid off grid inverter. At the same time, it is necessary to inspect the connection points of each cable at work site by field inspection and thermal imager. 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.
