solar street light is to use solar energy to achieve the purpose of luminous power, although various aspects are better than the traditional street lamp, but also can appear fault, so want to learn some screening method, then the solar street lights breakdown? Solar street lamps troubleshooting methods: 1, controller test. Controller turns red, said it was charging, the battery is full of red light flash, with pulse controller are small current charging. 2, yellow light controller. Said the battery has lost electricity for normal lighting, at this time, such as the battery line disconnect again again lit up, then the controller test for the battery is after a day of charge and make the battery capacity increased, is not a battery of floating voltage ( Disconnect the load of the recovery voltage) 。 3, solar panels Solar cell is also known as 'solar cells' or 'cell', is a kind of electricity generation by using sunlight directly photoelectric semiconductor wafer. 】 。 Solar panel connection can cause not charging properly such as is not very strong, is usually characterized by a voltage ( Voltage meter test) Normal, open circuit voltage at 17. More than 5 v, but there is no current. The phenomenon of panels line not connected well ( Welding cold joint or joint unstable) Screening method can be directly behind the panels of black electrical cover opened, direct voltage, ampere meter for testing data. 4, storage battery. Battery charge and discharge should be normal under normal conditions, such as detecting the voltage in 12 v above, and connect the lights ( Load) Said the battery voltage within a short period of time after falling pressure has been damaged. Another battery in waterproof casing inlet caused is negative when the short circuit and to detect the correct voltage, is usually a high voltage, low voltage, caused by water excessive battery discharge voltage fall below 10 v, the battery such as after normal circulation of small current charge and discharge can be normal use, such as can't normal use will need to be replaced, lead-acid battery' Lead-acid batteries, VRLA) , it is a kind of electrode is mainly composed of lead and its oxide, electrolyte battery is a sulfuric acid solution. 】 Normal after three years due to the reduced capacity will result in to turn off the lights of time every day or rainy day ahead of time to reduce, at this time is a normal phenomenon. 5, led light source. Light source under the condition of the battery voltage is normal can work normally, such as solar energy lamp is not bright, can put the lamps and lanterns of positive and negative pole directly to check on the cathode, the batteries are as the light source can light up the lamps and lanterns is good, the said controller didn't give power of lamps and lanterns. Phenomenon, rainy day after a long time, the battery voltage is not enough, The controller for the protection of the battery voltage is 11. 3 v and 22. 6 v, as long as the battery is lower than the following voltage, the controller will be forced to turn off the lights) Will have to wait for the battery again after a full charge; Voltage up to 12 v ( 24V) After, lamps and lanterns can work normally. Such as lamps and lanterns is directly connected to the battery is not bright, indicates a problem with the lamps and lanterns should this phenomenon is, adjust the control circuit of the lamp control unit (a problem Big electric current, voltage breakdown or parts fall off) , the situation will contact the factory to replace. 6, if the lamps are bright in the daytime, or is not close the lamp in the daytime. This kind of situation said solar panels failed to pass the controller to recharge the battery during the day, then we can use the method of article 1, 3 testing solar panels and controller, or is the controller when the connection because of is negative after the cause of the controller components burnt down.
