The Status of Inverter in Photovoltaic Power Station

Inverters play a crucial role in photovoltaic power plants. Specifically, its importance is mainly reflected in the following aspects:

1. Dc to AC conversion:

The electricity generated by photovoltaic modules is direct current (DC), while most power systems and electrical equipment require alternating current (AC). The main function of the inverter is to convert the direct current generated by the photovoltaic module into alternating current, so that it can be connected to the grid or directly supplied to the electrical equipment.

2. Maximum power point tracking (MPPT) :

The inverter usually has the maximum power point tracking function, which can adjust the operating point of the photovoltaic module in real time, so that it always runs near the maximum power point, thereby maximizing the power generation efficiency of the photovoltaic power station.

3. Voltage and frequency stability:

The inverter can stabilize the output voltage and frequency to ensure that the power quality meets the standard and avoid damage to the electrical equipment.

4. Fault detection and protection:

The inverter has a variety of built-in protection functions, such as over voltage, under voltage, over current, short circuit, and over temperature protection, which can cut off the power supply in time when the equipment fails to prevent equipment damage or fire and other safety accidents.

5. Data monitoring and communication:

Modern inverters usually have data monitoring and communication functions, which can monitor the operating status of photovoltaic power stations in real time, such as power generation, voltage, current, temperature and other parameters, and upload the data to the remote monitoring platform, which is convenient for power station managers to carry out real-time monitoring and operation and maintenance management.

6. Improve system reliability:

Inverters are usually designed with redundancy and backup functions. When the main inverter fails, the backup inverter can quickly take over the work to ensure the continuous and stable operation of the photovoltaic power station.
