What Is the Solar Electricity Inverter?

Many regions around the world are facing a series of power challenge, including rising electricity price, power shortage, and frequent blackout. To ensure stable power, solar power generation has become a focus of attention in the energy market. Solar system generate electricity using solar electricity inverter, which convert the direct current (DC) generated by solar panels or battery into alternating current (AC) to power loads. With the widespread adoption and application of solar power generation, solar inverter technology has continuously evolved, evolving from a simple "power conversion tool" to a core component that balances efficiency, safety, and intelligent management. Why do solar inverter play such a crucial role in solar system?

What is the solar electricity inverter?

An inverter is an electronic device that serves as a key interface in a solar power system. Its primary function is to convert the direct current (DC) generated by solar panel into alternating current (AC) suitable for home or commercial use. A solar power system consists of solar panel, charge controller, inverter, and battery. The inverter is the "brain and heart" of the solar system, responsible for both power conversion and system operation control. Without solar electricity inverter, the electricity generated by solar panel cannot directly power household appliances. Widely used in residential solar system, commercial and industrial solar system, energy storage system, and power supply in remote areas, these inverters are essential core components in solar power system.

What are the types of solar electricity inverter?

Common inverter types in the solar market generally include off grid solar electricity inverter, on grid solar electricity inverter, and hybrid solar electricity inverter. Xindun primarily produces off grid solar electricity inverter. Different inverter types play an important role in different power supply environments.

Off Grid Solar Electricity Inverter

Off grid solar electricity inverter operate independently of the public power grid. They primarily convert the DC power generated by solar panel or stored DC power in battery into AC power to power the load. They are typically used in conjunction with battery. When the solar panel are generating sufficient power, a portion of the power is converted to AC power by the inverter to power the load, and the excess power is stored in the battery for power supply. When sunlight is low or at night, the battery power is converted to AC power by the inverter to ensure continuous power supply to the load. Off grid solar electricity inverter are primarily used in areas with poor or unstable power grid coverage, such as remote mountainous areas, rural areas, meteorological observation stations, and border outposts. Off grid solar electricity inverter also play a vital role in areas where power supply reliability is paramount and cannot be interrupted by grid outages, such as emergency power system in small hospitals and backup power supplies for critical communication base stations.

On Grid Solar Electricity Inverter

On grid solar electricity inverter connect to the public grid and primarily convert the direct current (DC) generated by solar panels into AC power with the same frequency and phase as the grid. A portion of this power is then directly supplied to local loads, while the remainder is fed into the public grid. If the solar panels' power generation is insufficient to meet local load demand, the remaining power can be directly drawn from the public grid. Unlike off grid solar electricity inverter, on grid solar electricity inverter generally do not require a battery pack. Energy storage and distribution rely primarily on the public grid, resulting in a relatively simple system architecture. In the event of a grid outage, the loads will cease operation. On grid inverter are suitable for cities and urban areas with stable grid coverage. After installing solar panel, residents can use on grid solar electricity inverter to feed excess power into the grid. This not only meets their own electricity needs but also allows them to generate a certain amount of income by selling electricity, enabling them to generate electricity for their own use and then feed surplus electricity to the grid. For commercial and industrial users, large scale installation of on grid solar system can effectively reduce their electricity costs and carbon emissions, aligning with the concept of green development.

Hybrid Solar Electricity Inverter

Hybrid solar electricity inverter, also known as on&off grid hybrid inverter, combine the functions of off grid and on grid inverter. They can be connected to the public grid for self use or combined with battery banks for energy storage and off grid power supply. They can flexibly switch between operating modes based on grid conditions and user needs. During the day, solar power is prioritized to charge the battery, while at night, it automatically switches to battery power during peak hours, reducing electricity costs. In the event of a grid outage, they can seamlessly switch over in milliseconds, keeping critical loads running. They are favored by hospitals, hotels, commercial facilities, and residential markets, becoming a mainstream product in the market.

How to choose a solar electricity inverter?

Choosing the right solar electricity inverter directly impacts system efficiency, lifespan, ongoing maintenance costs, and payback period. Grid environments, load types, power supply requirements, and policy guidelines vary from country to country. When selecting solar electricity inverter, you should comprehensively consider factors such as the inverter's power, parameters, product performance, capacity, price, and return on investment.

What solar electricity inverter size is appropriate for a solar system?

The inverter's specifications affect the overall operating efficiency of a solar system. The inverter's rated power directly affects the system's AC power output and its stability under varying loads. The inverter's rated AC output power must be sufficient to meet the total power of all loads in the system, especially the maximum power of the simultaneously activated load. Also consider the inverter's peak power, which is the maximum load it can withstand for a short period of time, typically a few seconds. For inductive loads with high starting currents, such as refrigerators and air conditioners, the peak power should be at least 1.2 times the starting power to avoid triggering the inverter's protective shutdown due to excessive starting current. For example, if the total power of the simultaneously operating loads in a home is 8KW, and the air conditioner's starting power reaches 10KW, an inverter with a rated output of 10 KW and a peak power of at least 12KW is recommended. The inverter's rated power should generally be slightly higher than the maximum load by 10% to 20% to handle short term peaks and ensure long term stable system operation.

Also, it's important to ensure that the inverter's voltage, number of phases, and type, along with other parameters, strictly match the system configuration and installation scenario. Regarding voltage, the DC input voltage must match the series voltage of the solar panel, ensuring the inverter's MPPT voltage range covers the operating voltage range of the solar panel for efficient power generation. For example, if the Vmpp voltage of the solar panel connected in series is 300V-450V, select solar electricity inverter with MPPT voltage range that includes this range. The AC output voltage must conform to the standard voltage and frequency of the local power grid. Regarding phase selection, single phase inverters are suitable for smaller loads (typically ≤10KW), such as homes and small businesses. They offer simple installation and low cost. Three phase inverters are suitable for larger loads, such as industrial and commercial plants and large solar power plants, or for applications involving three phase loads such as three phase motors. They provide more stable power supply and can handle higher power. Selecting the appropriate solar electricity inverter based on the actual load will improve system operating efficiency.
