In the field of new energy, photovoltaic inverters and energy storage inverters are important equipment, and they play an indispensable role in our lives. But what is the difference between the two? We will analyze these two inverters in depth from the aspects of structure, function and application scenario.

Different design structure: First of all, from the principle point of view, the photovoltaic converter is relatively simple structure, mainly composed of DC/DC converter, filter, inverter, etc., inverter is mainly a kind of equipment that converts DC power into AC power, Energy storage inverter topology,it uses semiconductor devices (such as field effect transistors or thyristors, etc.) switching characteristics, The power supply voltage and current are controlled by fast switching, thus achieving the conversion of direct current to alternating current.Contact Us

The energy storage transmitter (PCS) is a broader concept, which involves the design of energy storage battery packs, battery management systems, inverter control chips, temperature sensors and other aspects to achieve power transmission, conversion and control. PCS mainly includes rectifier, inverter, DC/DC conversion and other modules, of which the inverter module is only one of its components.

functional characteristics: From a functional point of view, the photovoltaic inverter mainly focuses on converting the direct current generated by solar photovoltaic panels into alternating current to supply the power grid or electrical appliances, it through the internal circuit and control module, optimize the output power of the solar photovoltaic array, the direct current generated by the photovoltaic panel for a series of processing, the final output in line with the grid requirements of alternating current, which Series inverters have the advantages of high efficiency, strong stability, controllable power generation, etc. The parallel inverter has the advantages of strong flexibility, low maintenance cost and high fault tolerance rate. Hybrid inverters can have the advantages of series inverters and parallel inverters at the same time to improve the power generation and stability of photovoltaic power stations.

The energy storage transmitter pays more attention to the bidirectional conversion and intelligent management of electric energy, which can not only convert direct current into alternating current, but also convert alternating current into direct current for storage. In addition to the conversion from DC to AC, it also supports BMS/EMS linkage, cluster-level management, increasing the amount of charge and discharge, local independent management of peak cutting and valley filling, and intelligent scheduling of charge and discharge operations of the energy storage system.


Application scenarios: In terms of application scenarios, photovoltaic transmitters are mainly used in solar power generation systems, such as household photovoltaic systems, industrial and commercial photovoltaic projects and large ground power stations. 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.

The energy storage inverter is more focused on the application of electrochemical energy storage systems, such as energy storage power stations, centralized or cluster, industrial and commercial and household scenarios. In these scenarios, the energy storage inverter realizes the efficient use and storage of renewable energy by intelligently managing the charging and discharging process, providing stable and reliable power support for various application scenarios.

Common points and differences: In common, both are power electronic devices for the conversion and regulation of electrical energy 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, because energy storage inverters require integrated battery management systems, their costs are relatively high. The function of the photovoltaic inverter is relatively single, so the cost is usually low, at the same time, the energy storage transmitter also has higher requirements in terms of safety, in addition to meeting the basic electrical safety standards, but also need to consider the safety of the battery management system, as well as the protection measures in the case of battery panel inverter.

In summary, photovoltaic inverters and energy storage inverters have obvious differences in principle, application scenarios, power output, cost and safety. In practical applications, the appropriate device should be selected according to the specific requirements and scenarios.Contact Us
