The best solar inverter is the heart of the solar photovoltaic system. The solar inverter is one of the most important components in the solar structure. The inverter converts the energy output by the solar panels into a form of consumable electricity used in residential or commercial properties. Direct current is power that flows in one direction in a circuit and assists in providing current when there is no electricity.
Simply put, a best solar inverter converts direct current (DC) power to alternating current (AC) power. This is important because solar panels generate direct current, but ordinary homes, businesses, and appliances require alternating current to operate. Therefore, without an inverter, you are actually creating a large amount of solar energy that can be stored but actually cannot be used (if you have solar cells). Therefore, solar inverters are generally regarded as the “gateway” to solar systems.
Can Solar Panels Function Without Solar Inverters?
No, solar panels will not function without an inverter. DC currents do not have enough power to produce anything functional for appliances and home circuits.
Best Solar Inverter and Its Importance
A solar inverter is one of the most important components of a solar structure. The inverters alter the energy output from solar panels into usable electricity.
How Does a Solar PV Inverter Work?
It functions by engaging the fluctuating direct current from the solar panels and converting it into alternating current output. Household appliances mostly operate on alternate current but not direct current. It is the reason why solar panels must convert the direct current output collected by solar panels.
Technically, the sun’s rays hit on your photovoltaic cells (solar panels), designed with semiconductor layers of crystalline silicon which is a dominant semiconducting material used for the production of solar cells. The semiconductor layers of silicon are a mixture of negative and positive layers connected by a junction.
The layers take in the light and transfer the solar energy to the photovoltaic cells. The energy runs around and knocks electrons loose. The electrons travel between the negative and positive layers generating an electric current, generally referred to as direct current.
Once the energy is formed, it is either discharged directly to an inverter or stored in a battery for later use. This eventually depends on the solar panel inverter system you use.
When the energy produced is sent to the inverter, it is normally in the direct current form, although your home needs an alternate current. The inverter grasps hold of the energy and passes it via a transformer, consequently discharging an alternate current output.
In brief, the best inverter runs the direct current via two or more transistors that switch on and off fast and the transistors supply the two different sides of the transformer.
Five Functions of Solar Inverter
Interface with the utility grid
The solar inverter needs to interface with the grid. The inverter can ensure that in the event of a temporary power failure, the power from the solar panels will not be output to the transmission lines outside your home. This prevents electric shocks to line workers who may be troubleshooting or repairing wires.
When your home does not require power or the battery is full (if you connect them to a solar system), your inverter will also feed the electrical load into the grid.
Ensuring the production of sufficient and clean electricity
The solar panel inverter is responsible for continuously tracking the voltage of the solar panel to determine the maximum operating power of the solar panel, ensuring that the system always generates the most and cleanest electricity.
Arc detection and dangerous shutdown
The inverter also needs to be turned off when it detects a dangerous arc, which is caused by the aging of the system and the degradation of materials in the home wiring and solar panels. Some inverters perform better than others in terms of safe shutdown.
Power conversion work
It converts the DC (direct current) power (usually in the range of 200V-1500VDC) generated by the solar array into AC (alternating current) power usable by our electrical equipment, such as 220VAC used in Egypt, 240VAC used in Australia, and 110/ 120VAC is used in the United States.
Maximize Power Output
Solar inverters constantly keep track of the solar array’s voltage to find the maximum power at which the modules can function. If modules have deteriorated or shading may occur due to environmental obstructions such as trees, buildings, dirt, etc., the inverters can inadvertently point out the string’s wrong peak. This minimizes the system’s normal energy production.
Report on Power Production
Solar inverters assist you to monitor your solar system’s power output. These smart inverters come along with communication capabilities via hardware Ethernet, Wi-Fi or Bluetooth. With their technology, you can notice the error codes, power reduction data, and diagnostics from inverters on their customized smartphone apps or computers.
