On Grid Inverter Price List
On grid inverters are also called grid tie inverters, which are generally divided into solar PV power generation on grid inverters, wind power generation grid tie inverters, power equipment generation on grid inverters, and other equipment generation grid tie inverters. The biggest advantage of on grid inverter is the high power and low cost of the system.Grid tie inverters are generally used in the system of large-scale solar photovoltaic power stations. Many parallel photovoltaic strings are connected to the DC input of the same centralized inverter. Generally, three-phase IGBT power modules are used for higher power, and field effect transistors are used for lower power. At the same time, it uses a DSP conversion controller to improve the quality of the generated power, making it very close to a sine wave current.
Difference between On Grid Inverter and Off Grid Inverter
Inverter refers to a device that converts DC power (such as storage battery) into AC power (usually 220V, 50Hz sine wave). Grid tie inverters are generally used in the system of large-scale solar photovoltaic power stations. Many parallel photovoltaic strings are connected to the DC input of the same centralized inverter. The off grid inverter can work independently after leaving the grid, which is equivalent to forming an independent small grid. This article will introduce on grid inverters and off grid inverters, discuss the working principles of off grid inverters and on grid inverters, as well as their differences.
Solar On Grid Inverter Circuit Design
As the energy constraint becomes increasingly evident, the solar PV power generation system attracts growing attention. The direct current generated by solar cells and wind-powered generators should be inverted by inverters before being combined to the grid. Therefore, the design of solar on grid inverters determines whether the solar PV system will operate reasonably, efficiently, and economically. The control circuit, signal gathering circuit, and the switching tube drive circuit of solar on grid inverters need different adaptive power supplies. Thus an independent power supply should be provided for powering these circuits. The voltages of the designed auxiliary power supplies include +15V, -15V, and +5V. A single-ended flyback DC/DC topographical structure is adopted, with stable and reliable operation.

How to Read Solar On Grid Inverter Data Sheet?
What is the on-grid inverter data sheet? It's a sheet shows the on-grid inverter specs, so can judge if the inverter can be used in our system or not. It's an important matter to be able to read the sheet and understand it before buying the on grid inverter.
On Grid Solar System and Win-Win Relationship
It's a solar system that is connected and synchronized with the power grid. So, the electrical load will be fed from both sources which share to each other in feeding it. In cloudy days or at night where the solar system generation is low or even is not exist, the electrical load takes its power requirements from the power grid. And in sunny days where solar generation exceeds load power requirement, the load take all its power requirement form the solar system and surplus solar generated electricity will go to the power grid to be used elsewhere.
Brief Introduction to On-Grid Inverter
The on-grid inverter must match grid sine wave phase and voltage, so can inject the AC current into it. The most important feature of such inverter is its ability to work without batteries, it based on solar panels or wind turbine and power grid presence only, so if the solar energy or wind energy are not sufficient to feed the load, it consumes his power requirements from the power grid.
Designing a Grid Tie Solar Power System for Your Home
Today we will introduce a home solar power system design below 10kW, which is installed on the roof of the house and connected to the grid of 220V or 380V. The maximum installation capacity is 25% of the capacity of the upper-level transformer. First of all, it is required to determine whether the load capacity of the roof can meet the requirements. The loading requirements of the solar power system equipment for the roof are greater than 30kg/m2.
How Much Electricity Does a Home Solar System Produce?
If you plan to design and install a grid tie solar PV system for your home, you will want to know how much electricity the system can produce each year. Now we will take the roof of 60m2 as an example to make this calculation. At present, the household solar power system generally adopts the monocrystalline silicon solar panel and polycrystalline silicon solar panel. Its specification is generalized as 36V 280W, and the single piece of solar panel generally has an area of 1.8 m2...
How to Troubleshoot the Wrong Wired On Grid Inverter?
As to the photovoltaic grid-tie inverter, the input end is connected to the photovoltaic component and the output end is connected to the power grid. The component has only positive and negative poles, and it is not easy to wire incorrectly. Since the component is a certain distance away from the inverter, it is required to add an extension cable. The correct connection method is that the photovoltaic connector has a female connector on one side and a male connector on the other side, so that the positive and negative directions will not change. However, some green hands will also make the two connectors of the extension cable the same. If the power inverter is connected, the positive and negative poles will be reversed.
