solar street lamps controller maintenance method how to make the service life of the solar street lamps controller growth? First discusses the problems of the controller, the controller in the solar street light system 【 Solar street lamps system consists of eight elements. 】 , the cost of than is very low, is in commonly 120 yuan - 200 yuan, although look is a humble small objects, but bear the large role,, if you choose not to be able to make the whole system stability and service life, and a relatively mature controller can also be done by function to reduce the cost of the whole system, achieve the goal of cost savings. Now is provided by small make up to you a few tips to make the service life of the controller. 1, exit some customers often find protection voltage, solar street light in bright after a period of time, especially after a rainy day in a row, street lamps will be for days or even a lot of day not bright, detect the battery voltage is normal, no fault in the controller, and all the lights. This problem have many project traders confused, in fact, this is 'to exit the under-voltage protection' voltage value, the higher the value, the longer the recovery time after undervoltage, also has caused many days could not light. On this question, industrial controller can let each customer according to the configuration set out of the voltage protection. But it is worth noting that the panel configuration must be reasonable, if the amount of charging panels daily discharge can't meet that night, in the long term, often in a deep discharge, battery life shortens greatly, so the panel configuration must enlarge allowance, configuration of panels, the greater the exit to protect the low voltage can be set up, it won't cause the impact on the battery. 2, heat dissipation many controller in order to reduce costs, does not take into account heat dissipation problems so that load current 【 When load current is refers to the motor load actual detect stator current value, this value changes with the size of the load. 】 Larger or charging current is larger, the heat increases, the controller of the field tube resistance was increased, a dramatic loss of charging efficiency, service life is greatly reduced after the tube overheating and even destroyed, especially the summer outdoor environment temperature is high, so a good cooling device should be controller is indispensable, iron or plastic casing is unable to meet the requirements of the summer heat, so the aluminum shell is preferred material controller hardware. 3、MCT【 MCT has multiple meanings. 】 Charging mode of conventional solar controller' Called the solar controller solar charge controller, is used for solar power generation system, the control of multiple solar cell phalanx of battery and battery for solar power inverter load automatic control equipment. 】 Charging mode is to copy the mains charger three-step method, namely, constant current, constant voltage, floating three stages. Because of the energy of the mains grid is infinite, without constant current charging 【 Constant current charging refers to the charging current is maintained at a constant value. 】 , will directly cause the battery explosion and damage, but solar panels power of street lamp system is limited, so it survives mains controller of constant current charging method is not scientific, if the panel is greater than the current controller for the first period of limitation of current, then caused the fall of charging efficiency. MCT charging ways is the maximum current track panels, not wasteful, by detecting the battery voltage and the calculation of temperature compensation value, when the battery voltage to the peak, then take the pulse of a trickle charging method, can let the battery is also to prevent the battery overcharge.
