With the rapid development of renewable energy and the need for dynamic balance between energy supply and demand, energy storage technology is becoming increasingly important. Energy storage inverters, as key energy conversion devices, play a crucial role. Energy storage inverters achieve the balance of energy storage and output by converting electrical energy into potential energy in the storage medium and then releasing it when needed. Next, we will introduce in detail the advantages of energy storage inverters and their important role in renewable energy and power systems.

1. Energy Balance and Flexible Dispatching

As a key device for energy storage and output, energy storage inverters have flexible energy dispatching capabilities. It can store excess electricity during peak power generation periods and release it during peak demand periods according to the needs of the power system to balance the grid load. This flexible energy scheduling ensures the stability and continuous power supply of the power system.

2. Addressing the Challenges of Intermittent Energy Sources

Renewable energy sources, such as wind and solar power system, are intermittent and uncertain, which poses challenges to the power system. Energy storage inverters convert the electricity generated by intermittent energy sources into reliable energy storage media, which can be released when needed to provide a continuous power supply. This feature makes energy storage inverters an important technical means to solve the volatility of renewable energy.

3. Improve the Stability and Reliability of the Power System

Energy storage inverters have stable and reliable characteristics in the power system. It can quickly respond to the needs of the power system, provide emergency solar panel backup power system, and provide smooth power supply conversion in the event of power failures or emergencies. In addition, energy storage inverters can also provide uninterrupted power to avoid the impact of power outages on users. This stability and reliability make energy storage inverters an indispensable part of the power system.

4. Energy Efficiency and Energy Saving

Energy storage inverters have the advantages of high efficiency and energy saving in energy conversion. It can convert energy from one form to another while minimizing energy loss. This efficient conversion helps improve energy utilization, reduce energy consumption, and reduce reliance on traditional energy sources. The energy-saving characteristics of energy storage inverters make them an important technical equipment for sustainable energy development and environmental protection.

5. Application Areas of Energy Storage Inverters

Energy storage inverters are widely used in multiple fields. In distributed energy systems, energy storage inverters are used to convert and store the electricity generated by renewable energy into usable electricity and interact with the grid. In the field of electric transportation, energy storage inverters are used for charging and discharging electric vehicles, providing convenient energy storage and output. In addition, energy storage inverters are also widely used in microgridsd energy management, solar PV power systems, wind energy systems, solar battery power station applications and other fields.

Why the Brief Analysis of the Four Working Modes of Solis Energy Storage Inverters

Based on the above characteristics, let's briefly analyze the four working modes of Solis energy storage inverters:

1.General Mode

PV power generation prioritizes self-consumption, with excess power used to charge the battery. If there is still excess power, it can be sold to the grid (if allowed by policy). When PV power plant is insufficient or at night, the battery is used to power the load. If both are insufficient, the grid will supplement the power.

General Mode

2. UPS Mode

In this mode, both PV and the grid are used to charge the battery. As long as there is a grid, the battery will not discharge. This ensures that the battery is always fully charged, so that it can automatically switch to solar battery power supply mode in case of grid outage or instability. This switching time is within 10ms, ensuring that the load can continue to be used.

UPS Mode

3. Economic Mode

The time period for battery energy system charging and discharging can be set. This mode is usually used in scenarios where the peak and off-peak electricity prices differ greatly.

During peak electricity prices: Use PV + battery to prioritize power supply to the load, and sell the rest to the grid (the battery is in discharge state at this time).

During low electricity prices: Use PV + grid to prioritize power supply to the load, and then charge the battery (the battery is in charging state at this time).

Economic Mode

4. Off-Grid Mode

During the day, the electricity generated by solar is used to supply the load, and the excess electricity is stored in the battery. At night, when there is no solar PV power generation for balcony、garden、roof、sod and so on, the battery is used to supply the load.

Off-Grid Mode


In summary, energy storage inverters, as key energy conversion devices, have multiple advantages. They provide flexible scheduling of energy balance, can cope with the challenges of intermittent energy sources, improve the stability and reliability of the power system, and have efficient energy conversion and energy saving characteristics. With the increasing demand for renewable energy and power systems, energy storage inverters will continue to play an important role in promoting sustainable energy development and the coordinated operation of power systems.
