Before the pv grid connected inverter is connected to the grid for power generation, it needs to take power from the grid, detect the parameters such as voltage, frequency, phase sequence, etc. of the grid power transmission, and then adjust the parameters of its own power generation to be synchronized with the grid electrical parameters.
The user must not touch the board at any point during operation or immediately after operating, as high temperatures may be present. Do not leave the design powered when unattended. Grid connected inverters (GCI) are commonly used in applications such as photovoltaic inverters to generate a regulated AC current to feed into the grid.
All that’s required is a Windows laptop which has Sunny Explorer installed. You can then use Sunny Explorer to connect your inverter via Bluetooth or Speedwire to change the grid parameters of your inverter. To have a customized grid setting for your inverter, you will need to apply for a grid guard code from SMA before you visit the site.
An on grid inverter is a device that converts DC electricity from solar panels into AC electricity, which is compatible with the electrical grid. Unlike off-grid inverters, which operate independently from the grid and require battery storage, grid on inverters work in conjunction with the grid.
For the inverter to be suitable for the local grid, the correct country standards must be selected. However, in some areas, customized grid settings of the inverter need to be configured to meet the special requirements of the local utility grid.
The control design of this type of inverter may be challenging as several algorithms are required to run the inverter. This reference design uses the C2000 microcontroller (MCU) family of devices to implement control of a grid connected inverter with output current control.
