    LiFePO4 battery advantage and disadvantage

    Advantage of Lithium Iron Phosphate Battery(LiFePO4 Battery) Long cycle life:  Under 80%DOD, the life cycle is 2000 times. In same working environment, LiFePO4 Battery Life is 5-6times longer than Lead acid battery. Safer: Unless under extreme situation, LiFePO4 battery will never explode. Bigger Capacity: In same volume, LiFePO4 battery capacity is 1.5times of Lead Acid Battery. Lighter: In same capacity and voltage, LiFePO4 battery weight is 1/3 of Lead Acid Battery. High Temperature Resistance: LiFePO4 Battery working Temperature range is -20℃ - 75℃. Without memory Effect.  Environment Friendly. Disadvantage of Lithium Iron Phosphate Battery (LiFePO4 Battery) Bad Low Temperature Property: Compare to Li Ion battery, LiFePO4 Battery energy density is much lower, therefore it is unable to charge and discharge in low temperature. High Cost: LiFePO4 Battery production has harsh requirement on the environment , and the poor processing performance of electrodes and increasing synthesis cost, which result in high production cost and low production yield. Poor product consistency: The synthesis reaction of LiFePO4 battery is a complex heterogeneous reaction with solid phase phosphates, iron oxides and lithium salts, plus a carbon precursor and a reducing gas phase, which make it very hard to achieve high product consistency.

    What is MPPT ?

    MPPT The MPPT controller's full name "Maximum Power Point Tracking" solar controller is an upgraded product of the traditional solar charge and discharge controller. The MPPT controller detects the solar panel's generated voltage in real time and tracks the highest voltage and current value (VI), allowing the system to charge the battery with maximum power output. It is the brain of photovoltaic system used in solar photovoltaic systems to coordinate the work of solar panels, batteries and loads. Overview The Maximum Power Point Tracking (MPPT) system is an electrical system that enables the photovoltaic panel to output more power by adjusting the working state of the electrical module. The DC power generated by the solar panel can be effectively stored in the battery. It can effectively solve the living and industrial electricity consumption in remote areas and tourist areas that cannot be covered by conventional power grids, and does not cause environmental pollution. The output power of a photovoltaic cell is related to the operating voltage of the MPPT controller. Only when operating at the most suitable voltage will its output power have a unique maximum. The sunshine intensity is 1000W/down, U=24V, I=1A; U=30V, I=0.9A; U=36V, I=0.7A; the output power is the largest under the voltage of 30. Principle To charge the battery, the output voltage of the solar panel must be higher than the current voltage of the battery. If the voltage of the solar panel is lower than the voltage of the battery, the output current will be close to zero. Therefore, for safety reasons, the solar panel has a peak voltage (Vpp) of about 17V when it is manufactured, which is set at a standard temperature of 25 °C. When the weather is very hot, the peak voltage Vpp of the solar panel will drop to about 15V, but in cold weather, the peak voltage Vpp of the solar energy can reach 18V. Now, let's go back and compare the difference between the MPPT solar controller and the traditional solar controller. The traditional solar charge and discharge controller is a bit like a manual gearbox. When the engine speed increases, if the gear position of the gearbox does not increase correspondingly, it will inevitably affect the speed. However, for the traditional controller, the charging parameters are set before leaving the factory. That is to say, the MPPT controller will track the maximum power point in the solar panel in real time to exert the maximum efficiency of the solar panel. The higher the voltage, the more power can be output through the maximum power tracking, thus improving the charging efficiency. In theory, the solar power system using the MPPT controller will increase the efficiency by 50% compared with the traditional one. However, according to our actual test, the final efficiency can be increased by 20%-30% due to the surrounding environment and various energy losses. . In this sense, the MPPT solar charge and discharge controller is bound to eventually replace the traditional solar controller. Features The main function of the MPPT controller is to detect the DC voltage and output current of the main circuit, calculate the output power of the solar array, and track the maximum power point. Figure 1 is a schematic diagram of practical application of disturbance and observation to achieve maximum power point tracking. The disturbance resistor R and the MOSFET are connected in series, and the average current through the resistor is changed by changing the duty ratio of the MOSFET under the condition that the output voltage is substantially stable, thereby generating a disturbance of the current. At the same time, the output current and voltage of the photovoltaic cell will also change accordingly. By measuring the change of the output power and voltage of the photovoltaic cell before and after the disturbance, the disturbance direction of the next cycle is determined, and when the disturbance direction is correct, the output power of the solar energy panel increases. The cycle continues to perturb in the same direction, and vice versa, in the opposite direction, so that disturbances and observations are repeated to maximize the output of the solar photovoltaic panel.

    Solar Street Light

    Street Light Solar - Basic Introduction The solar street light is powered by a crystalline silicon solar cell. The maintenance-free valve-regulated sealed battery (colloidal battery) stores electrical energy. The ultra-bright LED lamp is used as a light source and is controlled by an intelligent charge and discharge controller to replace the traditional utility lighting. Street light. No need to lay cables, no AC power supply, no electricity charges; DC power supply, control; good stability, long life, high luminous efficiency, easy installation and maintenance, high safety performance, energy saving, economical and practical. Can be widely used in urban main, secondary roads, residential areas, factories, tourist attractions, parking lots and other places. The light pole structure of the product parts: steel light pole and bracket, the surface is sprayed, and the battery board is connected with special anti-theft stainless steel screws. Street light solar energy - system composition The solar street light system can guarantee normal work in rainy weather for more than 15 days! Its system consists of LED light source (including drive), solar panels, battery (including battery incubator), solar street light controller, street light pole (including foundation) and auxiliary wire. Solar cell modules generally use monocrystalline silicon or polycrystalline silicon solar cell modules; LED lamp heads generally use high-power LED light sources; controllers are generally placed in the light poles, with light control, time control, overcharge and over discharge protection and reverse connection protection, The advanced controller has four seasons to adjust the lighting time function, half power function, intelligent charging and discharging function, etc.; the battery is generally placed underground or there will be a special battery incubator, which can be a valve-regulated lead-acid battery or a gel battery. Iron-aluminum battery or lithium battery. The solar luminaire works fully automatically and does not require trench wiring, but the pole needs to be mounted on the embedded part (concrete base). Street Light Solar - Working Principle The working principle of solar street light shows that under the control of intelligent controller during the day, the solar panel is irradiated by sunlight, absorbs solar light and converts it into electric energy, and the solar cell module charges the battery pack during the day, and the battery pack supplies power to the LED at night. The light source is powered to achieve the lighting function. The DC controller ensures that the battery pack is not damaged by overcharging or overdischarging, and has functions such as light control, time control, temperature compensation, lightning protection, and reverse polarity protection. Solar energy is an inexhaustible and most indispensable source of environmentally friendly energy. Nowadays, many devices are using solar energy as our energy supply, and solar street lamps are a very good application of solar energy. As an energy device, future applications will certainly be more extensive. Our company focus on batteries, we manufacture LiFePO4 battery for solar street light, welcome to try our solar street light batteries.
