<p>We want to know that a product may be in use for a long time there will be some problems affect the normal use of it, even if is the same as the <a href="https://www.srssolargroup.com/solar-street-light" target="_blank">solar street light</a>, although longer service life of <a href="https://www.srssolargroup.com/solar-street-light" target="_blank">solar street lamp</a>s, but may be installed in the process of using the error, or the user purchase to inferior configuration, can affect the solar street light is not bright. Solar lamp does not light the light, what are the more common problems?</p><p><br></p><p>The reason solar street light don't work</p><p><br></p><p>Solar street light the lamp light is generally not possible because of the controller problem, you can first to check whether the controller into the water, if it is not problem of the controller, the test battery voltage, the voltage is lower than 10.8 v, if not, then again and see whether there is voltage panels, if there is no voltage is in panels.</p><p><br></p><p>solar street light do not light, may be because of the solar system, may be the problem of LED light source. The lamp bead of solar led street lamp lamp is not bright completely, besides the quality problem of led illuminant itself, it is welding problem, should change the lamp bead that does not do in time or the lamp bead is welded firmly or more direct change lamp cap.</p><p><br></p><p>How to check solar street lamp batteries:</p><p><br></p><p>1, observe whether the surface of the battery is clean, there is no corrosion leakage phenomenon, if there is more dirt on the shell, with a damp cloth with washing powder can be wiped.</p><p><br></p><p>2. Observe whether the appearance of the battery is concave or bulging;</p><p><br></p><p>3. At least once every six months, the connecting screws between single batteries should be tightened to prevent them from loosing, causing bad contact and causing other faults. In the maintenance or replacement of the battery, the use of tools (such as spanner, etc.) must be with insulation sleeve to prevent short circuit.</p><p><br></p><p>4, the battery should be timely charged after discharge. In case of continuous cloudy and rainy days, resulting in insufficient battery charging, the power supply time of the power station should be stopped or shortened, so as to avoid excessive battery discharge. The maintenance personnel of the power station should charge the battery evenly on a regular basis, usually 2-3 times a quarter. For the battery that has been out of use for a long time (more than 3 months), it should be recharged before being put into operation.</p><p><br></p><p>5, winter to do a good job in the heat preservation of the battery room, summer to do a good job in the ventilation of the battery room, the battery room temperature should be controlled as far as possible between 5℃~25℃.</p><p><br></p><p>6. Keep the lighting surface of solar module array clean. In the area with little rain and bigger sandstorm, should be cleaned once a month, when cleaning, should use clear water to wash first, wipe off the water trace with clean soft cloth next, do not use corrosive solvent to wash, or with hard thing wipe. Cleaning should be done when there is no sunlight or in the morning and evening. It should be avoided to clean the photovoltaic modules with cold water during the day when they are heated by the sun. Very cold water will cause the glass cover of the photovoltaic modules to break.</p><p><br></p><p>7. Regularly check whether the wiring between photovoltaic modules is firm, and whether the wiring in the square junction box is firm, and tighten as required; Check whether the photovoltaic modules are damaged or abnormal, such as damage, grid line disappearance, hot spots, etc.; Check whether the by-pass diode in the junction box of the photovoltaic module is working normally. When the photovoltaic modules have problems, replace them in time, and record the specific location of the modules in the photovoltaic array in detail.</p>
