Photovoltaic component maintenance notice what?

Photovoltaic power generation system consists of a number of components, each component is not to be ignored is key, so in order to be able to better complete power work, should be based on the different characteristics of each component related maintenance work. Photovoltaic hair

photovoltaic power generation system consists of many components, the existence of each component are not to be ignored. Therefore, in order to better complete the power work, should according to the different features of various components for the corresponding maintenance work. Photovoltaic component maintenance need to pay attention to the following aspects. First, pay attention to solar cells maintain new photovoltaic policy providers should regularly clean the surface of the solar cell array lighting in advance. If lighting surface dirt, should wash first, and then use dry cloth gently wipe water, should not be used hard to wipe or use corrosive solvent to clean. Should check the junction box of the solar cell module, in order to avoid weathering. Second, pay attention to the maintenance of the battery pack battery maintenance can be said to be the most important thing in all the related work, because it will affect the whole system. The daily maintenance of valve-control sealed lead-acid battery are very low. Mainly to do some cleaning, indoor temperature control within the prescribed scope. In addition, the battery during the operation, should pay attention to observe whether terminal and the shell is overheating, and regularly check whether the battery bolt is loose. Third, pay attention to the output of the controller, the maintenance frequency converter controller, input terminal and terminal should be checked regularly, controller to control the storage battery charging and discharging of the preset threshold voltage shall not be arbitrarily adjusted, in case of confusion and control failure. Only when the abnormal battery state of charge and discharge, can invite related manufacturers for inspection and adjustment. Should also regularly check the inverter. If found some fault is difficult to make a decision, the accident shall be recorded in detail, and promptly notify the manufacturer to solve. In addition, still should pay attention to the daily maintenance of the inverter. Photovoltaic component maintenance should be paid attention to. Regularly check whether all parts of the frequency converter connection is firm, wiring insulation performance is good, without damage. In particular, it is necessary to check the inverter power supply module, input and output terminals of the potential danger of overheating or other problems, and examine the running situation of the inverter fan, etc.
