The photovoltaic junction box should be tested before use. The main items include appearance, airtightness, solar junction box fire resistance level, solar junction box and whether the diode is qualified. Please make sure the junction box is tested and qualified before use. Before placing the production order, solar junction box please determine the spacing of the wiring terminals and determine the layout process. When installing the junction box, solar junction box the glue should be uniform and comprehensive to ensure that the box body and the back plate are completely sealed. Be sure to distinguish the positive and negative poles when installing the photovoltaic junction box.
When connecting the contact terminal to the bus strap, solar junction box be sure to check whether the tension between the bus strap and the terminal is sufficient. When the welding terminal is in use, solar junction box the welding time should not be too long to avoid damaging the diode. When installing the cover, solar junction box be sure to fasten it firmly.
