What is the difference between photovoltaic inverters and energy storage inverters? 2024-05-08 15:14:55
In the field of new energy, photovoltaic inverters and energy storage inverters are important equipment that play an indispensable role in our lives. But what is the difference between these two? We will conduct in-depth analysis of these two inverters from the aspects of structure, function, and application scenarios. 1. Structural differencesFirstly, in principle, an inverter is primarily a device that converts a DC power source into an AC power source. It utilizes the switching characteristics of semiconductor devices such as field-effect transistors or thyristors to control the power supply voltage and current through rapid switching, thereby achieving the conversion of DC to AC power. Energy storage inverters (PCS) are a broader concept that involves converting and regulating electrical energy through power electronic devices, achieving power transmission, conversion, and control. PCS mainly includes modules such as rectification, inverter, DC/DC conversion, among which the inverter module is just one of its components.2. Functional characteristicsFrom a functional perspective, photovoltaic inverters mainly focus on converting the direct current generated by solar photovoltaic panels into alternating current for use in power grids or electrical appliances. It optimizes the output power of the solar photovoltaic array through internal circuits and control modules, processes the direct current generated by the photovoltaic panel in a series of ways, and finally outputs AC power that meets the requirements of the power grid. Energy storage inverters focus more on bidirectional conversion and intelligent management of electrical energy. It can not only convert direct current into alternating current, but also convert alternating current into direct current for storage. In addition to achieving the conversion from DC to AC, it also supports BMS/EMS linkage, cluster level management, and improves charging and discharging capacity. It can independently manage peak shaving and valley filling locally, and intelligently schedule the charging and discharging operations of the energy storage system. 3. Application scenariosIn terms of application scenarios, photovoltaic inverters are mainly used in solar power generation systems, such as household photovoltaic systems, industrial and commercial photovoltaic projects, and large-scale ground power plants. Its main function is to convert the direct current energy of the solar power generation system into alternating current energy and integrate it into the grid. Energy storage inverters, on the other hand, are more focused on their applications in electrochemical energy storage systems, such as energy storage power plants, centralized or series, industrial, commercial, and household scenarios. In these scenarios, energy storage inverters achieve efficient utilization and storage of renewable energy by intelligently managing the charging and discharging processes, providing stable and reliable power support for various application scenarios. 4. Commonalities and DifferencesIn terms of commonality, both are power electronic devices used for energy conversion and regulation to achieve stable operation of the power system. They all need to meet certain electrical safety standards to ensure the safe operation of the equipment.In addition, due to the need for an integrated battery management system, the cost of energy storage inverters is relatively high. The function of photovoltaic inverters is relatively single, so the cost is usually lower. At the same time, energy storage inverters also have higher safety requirements. In addition to meeting basic electrical safety standards, it is also necessary to consider the safety of the battery management system and protective measures in case of battery failure. ConclusionIn summary, there are significant differences between photovoltaic inverters and energy storage inverters in terms of principles, application scenarios, power output, cost, and safety. In practical applications, appropriate equipment should be selected based on specific needs and scenarios.

Lithium iron phosphate battery structure and the correct maintenance method 2023-08-25 17:08:26
LiFePO4 is used as the positive electrode of the battery, which is connected to the positive electrode of the battery by an aluminum foil, in the middle of which is a polymer diaphragm, which separates the positive electrode from the negative electrode, but the lithium ion Li can pass through it while the electrons e- can't pass through it, and on the right side of it is the negative electrode of the battery, which is composed of carbon (graphite), which is connected to the negative electrode of the battery by a copper foil. Between the top and bottom of the battery is the electrolyte of the battery, which is hermetically sealed by a metal shell. 1. The temperature should not be too highIf the UPS battery is used in an environment higher than the specified operating temperature, i.e., above 35C, the battery's power will continue to diminish, i.e., the battery's power supply time will not be as long as usual. If the equipment is charged at such temperatures, the damage to the battery will be even greater. Even storing batteries in a hotter environment will inevitably cause corresponding damage to the quality of the battery. Therefore, try to keep in the appropriate operating temperature is a good way to extend the life of lithium-ion batteries.2. Too low is not goodIf the use of lithium-ion in a low-temperature environment, that is, below 4C, the same will also be found in the use of UPS batteries time is reduced, and some of the original lithium-ion cell phone in a low-temperature environment and even charging. But do not worry too much, this is only a temporary situation, unlike the use of high-temperature environments, once the temperature rises, the molecules in the battery by the heat, it will be immediately restored to the previous power. 3. Life is movementTo maximize the effectiveness of lithium iron phosphate batteries, it is necessary to use it often, so that the electrons within the lithium battery is always in the flow state. If you do not use lithium-ion batteries often, please always remember to complete a charging cycle for lithium-ion batteries every month to do a power calibration, i.e., deep discharge and deep charge once. 4, do not mix the battery with metal objects, so as to avoid metal objects touching the battery positive and negative poles, resulting in a short circuit, damage to the battery or even cause danger.5, lithium iron phosphate battery should be in a clean, dry, ventilated environment, should prevent contact with corrosive substances, away from sources of ignition and heat.We, BOSA Energy, have been focusing on the safety research of lithium batteries. If you have any questions about lithium batteries, please contact us. Let us explore the world of lithium batteries together.
