Working principle of 2kva Solar Inverter

The working principle of 2kva Solar Inverter mainly includes the following steps:

1. Solar panel power generation: Solar panels (photovoltaic panels) absorb sunlight and convert it into direct current (DC). This step is the basis of solar energy system, and the efficiency of photovoltaic panels directly affects the power generation capacity of the system.

2. DC power transmission to inverter: The generated DC power is transmitted to 2kva solar inverter through cables. The input end of the inverter receives these DC powers and begins to convert them.

3. DC power conversion to AC power: The power electronic components inside the inverter convert DC power into AC power (AC). This process includes multiple sub-steps:

  • Rectification: First, the input DC power is converted into a high-frequency pulse signal through a rectifier circuit.
  • Inversion: Then, the high-frequency pulse signal is converted into a low-frequency AC signal using an inverter circuit.
  • Filtering: Finally, the clutter in the low-frequency AC signal is removed by a filter to obtain a pure AC output.

4. Output AC power supply: The converted AC power is transmitted to the home or commercial power grid through the output end of the inverter to supply power to various electrical equipment. 2kva solar inverter can output single-phase 220V or three-phase 380V AC power to meet different power needs.

5. Real-time monitoring and adjustment:

  • 2kva Solar Inverter has a built-in microprocessor to monitor input voltage, current, temperature and other parameters in real time, and make intelligent adjustments according to the grid and load conditions to ensure the stability of output voltage and frequency.
  • If abnormal conditions such as overload, short circuit or overheating are detected, the inverter will automatically take protective measures such as power off or alarm to ensure the safety of the system and equipment.

6. Grid-connected and off-grid mode: 2kva Solar Inverter can work in grid-connected mode or off-grid mode. In grid-connected mode, the inverter transmits excess power to the public grid to obtain power subsidies or reduce electricity bills. In off-grid mode, the inverter is independently powered, usually used in conjunction with batteries to ensure normal power supply when there is no public grid.
