A solar inverter is an essential component in a solar system. So how to choose a suitable solar inverter? here we come to find out.
1. Understand the commonly used solar inverters
It is essential to understand the different types of solar inverters and how they work. Generally speaking, solar inverters on the market are mainly divided into three types: grid-connected, off-grid and hybrid.
2. Compare the efficiency of different types of solar inverters.
Since efficiency is the core key of inverters, it is crucial to compare the efficiency of each inverter when choosing a solar inverter. While generally speaking the more efficient an inverter is, the better, but not all high-efficiency inverters are suitable for your solar system, so careful consideration is required when choosing an inverter.
3. Pay attention to the important parameters of each solar inverter.
Solar inverters do not generate electricity, but require specific parameters to function properly. Important factors that should be noted are its input DC voltage, output AC voltage, frequency and proper circuitry. For example, for a standard residential solar power system, the input voltages are 24 and 48 VDC.
4. Check if the solar inverter has a tracking device and provides optional accessories.
Just because you have a solar inverter installed doesn't mean you know it's working. With this in mind, some inverter manufacturers have designed chips or other tiny devices inside each inverter for fault tracking. Once a problem occurs, the relevant information will be fed back to the installation company to help deal with the problem in a timely manner. Beyond that, you should also check if the inverter offers optional monitoring accessories that can help you monitor your system. For example, by using a monitoring device, a home photovoltaic system user can know how much electricity the system is producing on a daily, monthly or yearly basis.
5. Make sure the inverter you choose has solid features.
Inverters are usually installed outside buildings. High temperatures generally increase the voltage of a photovoltaic system, while lower temperatures decrease it. Exceeding the maximum voltage will damage the inverter. Also, when the system voltage is too low, the inverter may stop working.
Therefore, it is best to choose a solar inverter that can withstand harsh weather conditions. For example, a robust inverter should have a solid enclosure or technology that guarantees stable performance even in unforeseen weather conditions.
6. Check the cooling system of the inverter.
A cooling system is necessary to prevent overheating. Because solar inverters are installed on the outside of buildings, they generate a lot of heat. Therefore, make sure that the solar inverter you choose is equipped with an efficient cooling system.
7. Search the web to find out the supplier's reputation.
Some world-renowned brands must always be known to everyone in this industry, but not everyone. You may come across brands you don't recognize, so you need to do a web search and see how they rank on Google or any other big search engine. You also need to read other people's news, blogs, forums, comments, comments and other forms of writing about them. If they generally have a good reputation, you can learn more about them and even decide to buy.
8. Inquire about the warranties and services provided by suppliers for their products.
Typically, solar inverter suppliers display the warranty of their products online. However, these guarantees may not be so accurate for each of his products. In fact, for simplicity and convenience, companies often display a general description of their warranty. While the main services are clearly shown, they might not be what you think. Therefore, please contact them and ask for the exact information required for the particular product of your choice.
The above are some suggestions for choosing a solar inverter. Through the above, you can find the solar inverter suitable for your solar system.
