The use of renewable sources of energy is gaining more and more popularity all over the world. The choice of alternative resources like solar power gives a unique chance to save both the planet and your money. Solar systems do not use fuel combustion and have a substantially reduced influence on the environment. In addition, these apparatuses give an opportunity to be independent of energy control. You generate your own electricity in needed amounts and become free from large fees.
However, it is important to recognize that a solar system is more than one solar panel as the majority think. This system is a complex mechanism with different interconnected elements, which are mostly hidden from the view. Besides panels, the technology can include batteries, charge controllers, electricity meters, junction boxes, cables, etc. However, mandatory components for every type are panels and microinverters.
On the market, there are different types of inverters, but microinverters are the leaders. A solar microinverter is a special device, which transforms DC electricity (Direct Current) from the sunlight into AC electricity (Alternating Current). The use of this device does not need a separate central inverter.
Microinverters are so important because people cannot use electricity directly from a solar appliance. The sun power gives DC energy that is used in gadgets (phones, tablets, etc.) and electronic parts of instruments that use AC. The DC to AC conversion is necessary because Alternating Current energy is simply transmitted over long distances, and it is appropriate for delivery through a distribution grid. AC energy powers all household devices, including TV, microwave, washing machine, iron, vacuum cleaner, and others.
A DC to AC transformation process is available because the microinverter changes the waveform of current. This device looks like a small piece of electronic equipment, which is installed directly at the panel site (one inverter for each appliance).
Key Benefits of Microinverters
Microinverters attract a lot of buyers because of the following positive signs:
- Every inverter is a separate device
The peculiarity of a microinverter is that it works for itself. This means that the damage of one appliance does not have any impact on another one, which will continue producing the energy. In comparison with a string inverter mechanism, which is connected with all panels, the microinverter is significantly more effective. This instrument allows panels to work without interference in any weather condition.
Solar systems present 27% more efficiency in partly shaded installations with the help of microinverters instead of string inverters.
- Low light activity
The instrument is also famous for its excellent low light performance. This feature ensures equal energy production in all seasons regardless of low or high light conditions. Most of the day is a work period for apparatuses with these devices as they can produce electricity from dawn till dusk.
- Constant total control
A solar system is a mechanism that needs to be regularly inspected and, unfortunately, can be broken. When you have a string inverter, you can lose efficiency because of one small damage due to the connections between all elements. In addition, it is often difficult to define the problem and find its location. Meanwhile, a separate microinverter allows inspecting each apparatus individually and save time.
- Reliability and security
The advantage of microinverters use is safety. The main problem of a string inverter system is that it contains plenty of high-voltage cables, which are installed on your roof. This is quite dangerous. However, due to a microinverter, the DC to AC transformation happens on the panel level, and it does not provide high-voltage power through your system.
