Photovoltaic (pv) grid inverter and off-grid inverter how to distinguish

Pv inverter as switching device of photovoltaic power station, also known as the inverter power supply regulator. According to use can be divided into: photovoltaic (pv) grid inverter and photovoltaic off-grid inverter, so for the two types of photovoltaic inverter we what to distinguish? Manufacturer of inverter is detailed to introduce below: on the basis of inverter in the use of distributed photovoltaic system we can be divided into independent model ( Off-grid type) And grid type two kinds, the two types of classification is the use of photovoltaic power generation system, is according to different USES photovoltaic system is divided into the two can be. The second is based on the waveform of the inverter itself modulation mode can be divided into square wave inverter, staircase inverter, inverter sine wave and combined three-phase inverter, which is by the inverter manufacturer production will differentiate waveform of the inverter itself. According to the division for grid-connected photovoltaic (pv) system to 3 can be divided into transformer type inverter and transformer type inverter. The mainly from different grid systems require a classification of photovoltaic inverter. Inverter manufacturer stressed: users according to their own needs to buy corresponding photovoltaic inverter.
