What Are The Differences Between The Functions Of Photovoltaic Inverters And Energy Storage Inverters?
Photovoltaic inverters can convert the variable DC voltage generated by photovoltaic solar panels into inverters of mains frequency alternating current, which can be fed back to commercial power transmission systems or used for off-grid power grids. Photovoltaic inverter is one of the important balance of system (BOS) in photovoltaic array system, which can be used with general AC power supply equipment.
Photovoltaic inverters can only generate electricity during the day, and the power generation is affected by the weather, which is unpredictable and other problems. In response to the above problems, energy storage inverters can perfectly solve: when the load is low, the output energy is stored in batteries , release the stored electric energy when the load peaks to reduce the pressure on the grid; when the grid fails, switch to the off-grid mode to continue supplying power. So what are the functional differences between photovoltaic inverters and energy storage inverters?
The functional differences between photovoltaic inverters and energy storage inverters are mainly reflected in the following points:
1. The self-use rate of traditional photovoltaic inverters is only 20%, while the self-use rate of energy storage inverters is as high as 80%;
2. When the mains fails, the grid-connected inverter is paralyzed, and the energy storage inverter can still work efficiently
3. In the context of the continuous reduction of grid-connected power generation subsidies, the income of energy storage inverters is higher than that of photovoltaic inverters.
4. Photovoltaic inverters can only generate electricity during the day, and the power generation will be affected by weather, which has unpredictable problems, and energy storage inverters can perfectly solve the problems of photovoltaic inverters.
