Since High Voltage solar battery is a high-tech product, some details in the production process, some inconspicuous problems such as gloves should be worn instead of gloves, reagents should be applied evenly, etc. are the enemies that affect product quality. Therefore, in addition to formulating a reasonable production process, the seriousness and rigor of the employees are very important. Here I will simply introduce the function of the battery backup solar process to give you a perceptual understanding.
• Encapsulation
• High Voltage solar battery test
• Front side welding
• Rear connection
• Lamination laying
• Component Lamination
• Trimming and framing
• Solder junction box
• High voltage testing and component testing
The module line is also called the packaging line. Packaging is a key step in the production of High Voltage solar batteries. Without a good packaging process, no matter how good the High Voltage solar battery is, it cannot produce good module boards. The encapsulation of High Voltage solar batteriescan not only guarantee the life of High Voltage solar batteries but also enhance the resistance strength of High Voltage solar batteries. The high quality and long life of the product are the key to winning customer satisfaction, so the packaging quality of the component board is very important.
Due to the randomness of cell production conditions, the performance of the produced High Voltage solar batteryis not the same. Therefore, to effectively combine High Voltage solar batteries with consistent or similar performance, they should be classified according to their performance parameters. The High Voltage solar battery test classifies the solar storage battery by testing its output parameters. To improve the utilization rate of High Voltage solar batteries, make high-voltage solar battery components with qualified quality.
It is to weld the busbar to the busbar on the front (negative pole) of the High Voltage solar battery. The busbar is a tinned copper strip. The welding machine we use can spot-weld the ribbon on the busbar in the form of multiple points. The heat source for welding is an infrared lamp (using the thermal effect of infrared rays). The length of the ribbon is about twice the side length of the High Voltage Lithium Battery. The excess ribbon is connected to the back electrode of the following cell when welding on the back
The back welding is to connect 36 pieces of High Voltage solar batteries in series to form a module string. The process used is manual. The positioning of the High Voltage solar battery mainly depends on a membrane plate, which has 36 grooves for placing battery pieces. The size of the slot corresponds to the size of the 48v 100Ah lifepo4 battery. The position of the slot has been designed. Different specifications of components use different templates. The operator uses a soldering iron and solder wire to connect the positive electrode (negative pole) of the "front High Voltage solar battery" to the back electrode (positive pole) of the "high voltage solar battery at the back" so that 36 pieces are connected in series in sequence and the leads are soldered to the positive and negative poles of the component string.
After the back is connected in series and passed the inspection, the component strings, glass and cut EVA, glass fiber, and backplane are laid according to a certain level and are ready for lamination. The glass is coated with a layer of reagent in advance to increase the bonding strength of the glass and EVA. When laying, ensure the relative position of High Voltage solar battery strings and glass and other materials, adjust the distance between High Voltage solar batteries, and lay a good foundation for lamination. Layers of laying: from bottom to top: tempered glass, EVA, battery sheet, EVA, glass fiber, backplane.
Put the laid High Voltage solar battery into the laminator, vacuum out the air in the module, and then heat to melt the EVA to bond the 51.2v lifepo4 battery, glass, and backplane together. Finally cool down and take out the components. The lamination process is a key step in the production of components, and the lamination temperature and lamination time are determined according to the properties of EVA. The lamination cycle time is about 25 minutes when we use fast-cure EVA. The curing temperature was 150°C.
During lamination, the EVA is melted and then extended and solidified due to pressure to form burrs, so it should be cut off after lamination. And framing is similar to putting a picture frame on glass. Install an aluminum frame on the glass module, increase the strength of the module, further seal the solar charger battery module, and prolong the service life of the High Voltage solar battery. The gaps between the bezel and glass components are filled with silicone resin. The borders are connected by corner keys.
Weld a box at the lead wire on the back of the module to facilitate the connection between the High Voltage solar battery and other devices or High Voltage solar battery.
High-voltage testing refers to applying a certain voltage between the component frame and the electrode leads to testing the withstand voltage and insulation strength of the component to ensure that the component will not be damaged under harsh natural conditions. The purpose of component testing is to calibrate the output power of High Voltage solar battery, test its output characteristics, and determine the quality level of components. The main thing is to simulate the test Standard test condition (STC) of sunlight. Generally, the test time required for a solar charger battery is about 7-8 seconds.
