Photovoltaic inverter An inverter that can convert the variable DC voltage generated by photovoltaic solar panels into mains frequency AC power, which can be fed back to the commercial transmission system or used by the off-grid grid. Pv inverter is one of the important system balance (BOS) in pv array system, which can be used with common AC power supply equipment.
Photovoltaic inverters can only generate electricity during the day, and the power generation is affected by the weather and has unpredictability. In view of the above problems, energy storage inverters can perfectly solve the problems: when the load is low, the output electricity can be stored in batteries, and when the load is high, the stored electricity can be released to reduce the pressure on the grid; When the power grid fails, switch to off-grid mode to continue power supply. 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. Under the background of continuous reduction of subsidies for grid-connected power generation, energy storage inverters have higher benefits than photovoltaic inverters.
4. Photovoltaic inverters can only generate electricity during the day, and the power of power generation will be affected by the weather, which has the problem of unpredictability. Energy storage inverters can perfectly solve the existing problems of photovoltaic inverters.
