Solar street lamps installed back light not bright?

A, detection, solar street light controller, the controller is the core of the solar street light. Said it was charging a red light, flashing said electricity has been full of, if it is a yellow light, said losing electricity, can't normal lights, now need to detect the battery voltage of solar street lamps, such as

 a, detection, solar street light controller' Used in solar photovoltaic systems, solar controller it full solar charge and discharge controller, coordinate the efforts of solar panels, battery, load, is a very important component in pv systems. 】 , the controller is the solar street lamps Solar street light is a crystalline silicon solar battery power supply, valve control type sealed and maintenance-free battery ( Gel battery) Store electricity, super bright LED as light source, lamps and lanterns and controlled by the intelligent charging and discharging controller, is used to instead of the traditional public power lighting lamps. 】 The core of the. Said it was charging a red light, flashing said electricity has been full of, if it is a yellow light, said losing electricity, can't normal lights, now need to detect the battery voltage of solar street lamps, if the battery is normal, then replace the new controller to see if normal, such as normal basic assurance is the controller is broken. Such as the light not bright, test wiring without loss. Second, excluding malfunction of the controller, the next step is to detect solar panels 【 Solar panels, 太阳能板) Is by absorbing sunlight, the solar radiation through the photoelectric effect or photochemical effect directly or indirectly converted into electrical energy device, the main material of most of the solar panel as the 'silicon', but because of the production cost is larger, so it widely used, we still have some limitations. 】 Whether can charge, often do not charge of main performance for voltage and current. At this time to test panels have good welding, joint panels on aluminum foil with and without electric current, if there is no current, the basic judge panels have been scrapped. If solar panels with electric current, but also pay attention to whether there is snow, unable to charge. Three, the battery is easy to fail. Many manufacturers use the battery is not waterproof, this leads to the battery in water are negative short circuit, voltage instability. When detecting watch battery voltage varies with the depth of discharge' In the process of the battery, the capacity of the battery out of its rated capacity percentage is called the depth of discharge. 】 Change, if can't normal use need to change new one. Four, to check the line is damaged. If wear insulating layer, an electric current passes through transmission light pole, can cause a short circuit, lamps and lanterns is not bright lights. By the way, some solar street light is bright during the day, not close. Eighty percent of this kind of circumstance is the controller component is burnt out. Above is about the solar street light not lit up some of the fault detection and maintenance methods, but the repair is the job of the professional staff of solar street lamps, we don't want to go to assist maintenance solar street lamps, or wait for maintenance personnel to repair.
