The inverter is used for AC power generation by converting DC power sources (for example- batteries).
It plays a crucial role in integrating renewable energy sources (such as solar energy, wind energy, and hydro energy) into the power grid.
The main function of the inverter is to provide a backup power supply during power outages, blackouts, or emergencies. It is widely used in uninterrupted power supply (UPS).
It improves the power quality by regulating the standard frequency.
It is very useful in remote areas and off-grid locations.
It helps to stabilize the voltage when a power outage or voltage fluctuation occurs.
This power-converting device is very beneficial in vehicles to provide convenient services.
Our Best-Selling Inverter Types
String Inverter
A string inverter system aggregates the power output of groups of solar panels in your system into "strings." Multiple strings of panels then connect to a single inverter where electricity is converted from DC to AC electricity. This single inverter is typically located in an electronics box that's placed on the side of your house or in your garage.
Hybrid Inverter
A hybrid solar inverter is a piece of equipment that is created by combining a solar inverter and a battery inverter into a single unit. This allows the hybrid solar inverter to intelligently handle power coming from your solar panels, solar batteries, and the utility grid all at the same time.
Basic Principles of Inverter
Inverters work by using a combination of electronic components that convert DC power into AC power. The basic components of an inverter include a DC power source, a switching circuit, a control circuit, and an output transformer. The DC power source can be a battery or a solar panel. The switching circuit is responsible for turning the DC power on and off at a high frequency. The control circuit regulates the switching circuit, while the output transformer converts the high-frequency AC power into a stable AC output.
Applications of Inverter
An inverter is mostly used in uninterrupted power supplies (UPS). The function of the power inverter circuit in UPS is to convert DC power to AC power at the required voltage level.
In industrial and commercial applications, the inverter is used for controlling the AC motor drive's input voltage.
In domestic appliances, the inverter is very essential for controlling the speed of the compressor and regulating the required power.
The inverter is primarily used in solar energy systems and wind turbine systems.
In electric aircraft and electric vehicles (EV), the power inverter is the most important device for power conversion and regulation.
It is used in high-voltage DC (HVDC) transmission.
This power device is used in the electroshock weapons.
Inverter Installation Precautions
Before installation, you should first check whether the inverter is damaged during transportation.
When selecting the installation site, it should be ensured that there is no interference from any other power electronic equipment in the surrounding area.
Before making electrical connections, be sure to cover or disconnect the DC side circuit breakers with opaque materials. When exposed to sunlight, the PV array will generate dangerous voltages.
All installation operations must be performed by professional technicians only.
The cables used in the photovoltaic system power generation system must be firmly connected, with good insulation and appropriate specifications.
All electrical installations must meet local and national electrical standards.
The inverter can be connected to the grid only after obtaining the permission of the local power department and all electrical connections are completed by professional technicians.
Before performing any maintenance work, first disconnect the electrical connection between the inverter and the grid, and then disconnect the DC side electrical connection.
Wait at least 5 minutes until the internal components are discharged before performing maintenance work.
Any fault that affects the safety performance of the inverter must be eliminated immediately before the inverter can be turned on again.
Avoid unnecessary board contact.
Observe the static protection code and wear an anti-static wrist strap.
Pay attention to and follow the warning signs on the product.
Visually inspect the equipment for damage or other dangerous conditions before operation.
Pay attention to the hot surface of the inverter. A heat sink of a power semiconductor or the like maintains a relatively high temperature for a period of time after the inverter is powered off.
