For PV industry professionals, PV inverters are no stranger, and for outsiders who need solar energy, they can be weird. Therefore, they may often have misunderstandings about these products. The following 14 misunderstandings are very common among many products.
Photovoltaic inverters are not important throughout the solar power generation process.
According to today's technology, PV inverters are the bridge between direct current [DC] and alternating current [AC]. DCs from solar panels cannot be used in ordinary homes, only AC. Therefore, there is a need for something that can convert DC to AC, and thus an inverter is invented. They are very important.
The cheaper they are, the better my life will be.
Everyone loves high quality, cheap products, but the opposite is true. One should not believe that the most expensive inverters are the best inverters, and one should not always emphasize cheap but ignore quality and other important functions. There are many different types of inexpensive inverters, but you need to compare their features and the long-term benefits they can provide.
Those made in Asia are the cheapest.
This is a clear misunderstanding that people usually have. Although Asia's average living standards and labor costs are not as high as in Europe or North America, their prices vary in brand, size, and function. Many of them are the cheapest, but not all.
Products made in China are always problematic.
China's cheap inverters are well known all over the world, but that doesn't mean that these products are always problematic. It is possible that the standards used in Europe, North America and Australia are different from those used in China. We know that some merchants reduce costs by sacrificing quality, but not all.
I can avoid hiring professionals to install inverters.
Unless you are a professional yourself, you can do so. Every inverter installation requires proper connection of solar panels, batteries and power meters. If you are not a professional, you may often make mistakes, which may result in incorrect connections, power failures, or even electrical leakage in the future.
6. Maintenance costs are high.
After installing PV inverters at home, in factories or power plants, maintaining them is a top priority for every user. These devices are rarely in trouble, and you don't even need to care about them every month. But you need to learn the easy way to maintain. So you don't have to worry about the extra cost being too high.
7. SMA products are no longer good now.
Although the company's market share has fallen sharply, its product quality is still sufficient for installation. The Sunny Boy inverter can still meet the various needs of customers.
8. Only micro inverters can be installed in rooftop photovoltaic systems.
Micro inverters are dedicated to rooftop PV systems, but they do not mean they can only be used in these systems. In fact, string inverters are generally considered to be effective products for consumers. Their nuisance is that the voltage of the entire system is usually higher.
9. The PV inverter cannot be installed outdoors.
This was true many years ago, but today it is completely wrong. Today's high-tech inverters are IP65 rated to ensure they can be installed inside and outside the house. Rainwater can't enter them, and the average temperature from the sun won't hurt them.
10. Only the garage is the best location for the drive installation.
If you install a solar PV system at home, you can install it in the garage, but this is not a sure thing. People usually choose a garage because this place is usually free of dust, moisture and interference. If your garage is not the place, you might consider installing it in another, better place.
11. The PV inverter cannot automatically report the problem.
The inverter is not a robot and it does not automatically report the problem. In fact, this idea is not true. Many of today's inverters have a chip inside that helps monitor their functions and automatically report problems when they encounter problems.
12. The impact of PV inverter manufacturers on the industry is not important to me.
I only buy inverters. Why should I care about manufacturers? However, I think you should pay attention to them because their technical and service attitudes must have a big impact on you. Buying a product from a good manufacturer must be better than a bad manufacturer.
13. Different types of inverters can be mixed for use in PV systems.
This is obviously not true. Photovoltaic systems can be divided into grids, off-grid and hybrid. They all need specific equipment to get them to work in the right way. For off-grid inverters, it cannot be used for grid-connected or hybrid systems. vice versa.
14. Warranty is not important.
This is a bad idea. Warranty means that the supplier promises you that his product will work effectively for a certain period of time. If you have trouble during this time, you can repair or replace the inverter for free according to different conditions. This also shows the confidence of the supplier, which is important to every customer.
in conclusion
Buying a PV inverter is not a complicated process, but avoiding these misunderstandings can help you buy better, more efficient products. Also, avoiding these misunderstandings can make your solar life easier and more fun.
