When We Choose Inverters, what is the most Critical?
Does the power meet your needs?
Different users have different expectations for the return of solar energy. Usually, the 6.6kw solar system corresponding to a 5kW inverter can cover your daily needs (there will be about 25% loss in DC-AC conversion), and in most cases, you can sell excess power to power companies to obtain certain benefits.
However, it is worth noting that it also depends on whether the area of your roof / solar installation is large enough to install the required panels.
What is the warranty commitment?
Generally, the service life of a grid-connected inverter is 10 to 20 years. You should expect the best quality products to last at least 10 years.
The warranty period of a solar inverter is 5 to 12 years, and more and more manufacturers provide extended service warranties. Most retailers now offer a warranty of 8 to 10 years. Obviously, the longer the warranty period, the more protection you get.
Therefore, please check the warranty of the equipment and weigh it against other functions of the system to help you make a wise decision decide which inverter is best for you.
Do you plan to upgrade in the future?
If you plan to upgrade the power of the solar system in the future, there is no doubt that you need a higher power inverter. If you want to install batteries to store electric energy in the future, whether you can connect batteries externally is your concern.
Can I track the working state of the inverter?
Most solar inverters have display lights to indicate whether the device is in the on, off, or standby state. They can also have a digital display (usually a scrolling display) of accumulated power generation, real-time power generation, and other information, and have matching apps to directly view relevant data records on mobile phones, tablets, and other devices.
Searching for an Inverter supplier, wholesaler, manufacturer from China, you can get high-quality products at a nice price.
