Controller for battery charged rural use solar street light price a few

Solar controller is divided into control and electric, half power controller used for solar street lamps and other lighting system and solar power system, the control of battery charging and discharging too lead to real life problems. Here are several kinds of conventional controller for battery charging



solar controller is divided into control and electric, half power controller for 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. 】 Such as lighting system and solar power system, the control of battery charging and discharging too lead to real life problems. Here are several kinds of conventional controller for battery charging methods: 1, the constant current charging method of constant current charging method is used to adjust the charging device output voltage or change with the resistance of the battery in series, the intensity of charging current unchanged of charging method, the control method is very simple, but due to the capacity of storage battery can accept current is as for the recharge gradually decreased, so the late charge, the charging current for electrolysis of water to produce gas, can make the gas too much; 2, constant voltage charging power supply in the process of charging method, constant voltage charging voltage constant value in all the charging time, gradually rise, as the real time voltage of the battery current gradually decreases. Compared with constant current charging method, the charging process is more close to the optimum charging standards, very little this charging method electrolysis of water, avoid the battery overcharge, but at the beginning of the charging current is too large, will have a big impact to battery life, and easily make the battery plate bending, so cause scrap; 3, charging method ( 1) Phase method: first of all, with constant current charging to a predetermined voltage value, and then to complete the rest of the constant voltage charging; ( 2) Three-stage charging method: at the end of the charging and using constant current charging, with constant voltage charging in the middle. When the current attenuation to the preset value, by the second phase transformation to the third stage. This method can minimize the volume, but as a kind of fast charging method is used, is still a certain limit. Above is yangzhou yingli solar street lamps factory staff summary of several kinds of conventional controllers to the battery charging method, selecting a correct way can guarantee the service life of the battery charging, thus ensuring the normal lighting, solar street lamps later we will introduce several to battery fast charge method, if you have any other questions can be consulting us.
