Differences between Energy Storage Inverter and Photovoltaic Inverter

Energy storage inverters and photovoltaic inverters are two types of power electronic devices that play an important role in energy conversion and management. Both inverters are converse DC electricity to AC electricity, but they are completely difference. In this blog post, we’ll explore the differences between these two types of power inverter.

What are Energy Storage Inverter and Photovoltaic Inverter Mean?

Energy Storage Inverter

Energy storage inverters are the devices that convert the direct current(DC) from a battery into alternative current that can be used by the grid or appliances. During the conversion, the energy storage inverter needs to regulate and manage the charging and discharging process of the battery system, adjust the the frequency and balancing the power of the grid as well.

Power Conversion System(PCS)

Power conversion system is a component connected between the energy storage battery system and the power grid. The PCS controls the charging and discharging process of the battery and converts AC to DC power. It is composed of a DC/AC bidirectional converter, a control unit, etc.

Photovoltaic Inverter

The PV inverter is a device that converts direct current (DC) electricity from solar photovoltaic arrays into alternating current (AC) electricity that can be used by the grid or for self-consumption. The main function of a photovoltaic panel inverter is to optimize the output power of the solar photovoltaic arrays, and ensure the stability of the current and voltage.

Functions

The main function of the photovoltaic inverter is to convert DC power (from the solar photovoltaic array) into AC power in order to supply power to the grid or use equipment. It optimizes the output power of solar photovoltaic arrays and ensures current and voltage stability.

The main function of the energy storage inverter is to convert the DC power in the energy storage system (such as a battery) into AC power to supply power to the power grid or for personal use. Energy storage inverter manages the charging and discharging process of the energy storage system, controls the storage and release of electric energy, and supports grid frequency regulation and power balance.

Applications

PV inverters are widely used in rooftop solar photovoltaic systems, commercial photovoltaic projects and large-scale solar power plants, etc. Energy storage inverters are mainly used in energy storage systems to store or release DC power into AC power to meet power needs. It also plays a key role in areas such as photovoltaic systems, wind power systems and electric vehicle charging piles.

Therefore, energy storage inverters are mainly used for energy regulation and management of energy storage systems, while photovoltaic inverters are mainly used to convert solar photovoltaic power into AC power and connect it to the grid. Although they are different in function, in some applications, energy storage inverters and photovoltaic inverters can be used together to achieve collaborative work between energy storage and grid power supply of solar power generation systems. This integrated application can improve energy efficiency, balance power needs, and provide more reliable and sustainable energy solutions.
