What Should Be Understood Before Purchasing A Solar Inverter?

Solar panels are an indispensable part of any solar system, but solar inverter is another often overlooked key component.

Solar inverters are responsible for converting  DC electricity generated by solar panels into AC electricity available for households or businesses.

Before purchasing a solar inverter, you should understand the following eight important things.

Types  Of  Solar Inverters

There are various types of solar inverters on the market, each with its unique features.The most common types include string inverters, micro inverters, and power optimizers.

• A string inverter is a traditional choice that can convert direct current from multiple series panels.
• Micro inverters are installed on each individual solar panel to increase energy production and enhance system performance. This reduces efficiency degradation caused by cloud cover and nearby trees blocking the system
• The working principle of the power optimizer is similar to that of a micro inverter, which optimizes the output of each panel before sending DC power to the series inverter. Therefore, they must be used in conjunction with the central inverter unit.

Efficiency Is Important

The efficiency is an important factor to consider. It determines the efficiency of the inverter in converting DC current into AC current.

Higher efficiency means less energy loss during the conversion process, resulting in more electricity available for consumption.

When comparing different solar inverters, seek higher efficiency levels to maximize the overall performance of the solar system.

Monitoring And Data Recording

Monitoring the performance of solar energy systems is crucial for optimizing their efficiency and identifying any potential issues.

Many solar inverters have built-in monitoring and data recording functions, allowing you to track energy production, consumption and system operation status.

Some inverters offer smartphone applications or online portals that provide real-time data and alarms, allowing you to fully control and understand the solar system.

With more and more inverters providing remote monitoring of systems, dashboard displays are easier to read, understand, and interact with than inverter screens.

On Grid Or Off Grid System

Consider whether you plan to connect the solar system to the public grid, or if you want to completely disconnect from the grid.

• The on-grid system uses solar inverters synchronized with the public grid, allowing excess electricity to be fed back to the grid for credit or compensation.
• The off-grid system requires an inverter with battery storage function to store excess energy for future use when there is no sunlight.
• If you want to benefit from using solar cells as your backup power source, but also want to maintain stability in connecting to the urban power grid, choose a hybrid system.

Durability And Warranty

Solar inverters typically exposed to various environmental factors, such as heat, moisture, and dust. Therefore, it is crucial to choose an inverter that can withstand such conditions.

• Looking for inverters with high-quality structures and weather resistant enclosures to ensure long-term durability.
• In addition, please consider the warranty provided by the manufacturer, as a longer warranty period indicates the manufacturer’s confidence in their products.

Security Features

The solar inverter should have built-in safety functions, such as ground fault protection, surge protection, and anti islanding function.

Choose Reputable Suppliers

Looking for suppliers with a record of providing high-quality products and excellent customer service.They can guide you through the selection process and help you find the inverter that suits your needs.
