Introduction of off-grid solar inverter

2021-08-24
In AC photovoltaic power generation systems, off-grid solar inverters are an indispensable part. At present, due to various technical or policy reasons, it will take a long time for all independent photovoltaic AC power generation systems to be connected to the national unified power grid. . As a result, the market distinguishes photovoltaic inverters into off-grid solar inverters and photovoltaic grid-connected inverters.

In AC photovoltaic power generation systems, inverters are an indispensable part. At present, due to various technical or policy reasons, it will take a long time for all independent photovoltaic AC power generation systems to be connected to the national unified power grid. Therefore, the market distinguishes photovoltaic inverters into two types: photovoltaic off-grid inverters and photovoltaic grid-connected inverters.   There is no major difference in the main circuit structure between photovoltaic off-grid inverters and photovoltaic grid-connected inverters. The main difference is that photovoltaic grid-connected inverters need to consider the operation safety of the grid-connected and grid-connected inverters. That is, the ability to control special situations such as the same frequency, the same phase, and anti-islanding. And off-grid solar inverters do not need to consider these factors.
