What are the functions for grid tie inverter?
Grid tie inverter, also known as power regulators and power conditioners, are an integral part of solar panel system kit. The most important function of the solar panel inverter is to convert the DC power generated by the solar panel into the AC power used by the home appliance.
The inverter is the heart of the solar panel system kit. All the electricity generated by the solar panels must be processed by the solar panel inverter to output to the outside. The solar panel inverter plays an important role in the operation of the whole solar panel system kit. The following small series will introduce you to the functions of the grid tie inverter.
1. The maximum power tracking function to ensure maximum output power.
The current and voltage of the solar panel vary with the intensity of the solar radiation and the temperature of the solar module itself, so the output power will also change. In order to maximize the output power, the maximum output power of the panel should be obtained as much as possible. The MPPT tracking function of the grid tie inverter is designed for this feature.MPPT tracking is also called maximum power point tracking. According to estimates, the solar panel system kit configured with MPPT tracking can generate 50% more power than the solar panel system kit without MPPT tracking. Therefore, if you want to make more electricity in the solar panel inverter kit, don’t just look at the solar panels. How much of the electricity generated by the solar panels can be effectively output, or depends on the solar power inverter.
2.Anti-individual operation function to ensure the safety of the power grid.
Many people in the installation of solar panel inverter kit, with the mentality of “even if the power grid is out of power, their homes can also use the power”. The truth is when the power grid is out of power, their own solar panel inverter kit will also stop running.
The reason for this phenomenon is that the anti-islanding device is generally configured in the solar panel inverter, and when the grid voltage is zero, the solar panel inverter will stop working. Is there a feeling of being pitted? Don’t worry, listen to solar system manufacturers Mars Solar explain to you that the anti-island device is a necessary device for all PV grid tie inverters. The reason for this is mainly for the grid safety considerations. Imagine, power grid power outages, grid workers have been on the battlefield to repair the circuit, and your home’s solar panel inverter kit system is still continuously uploading power,it is easy to cause a safety accident.
If you really want to use solar power electricity in your home when the power grid is out of power, you can consider installing a solar power electricity off-grid system, so that the solar power electricity generated by the solar panels will be stored and used when the user needs it.
3. According to the output power of the solar panel, automatic operation and shutdown.
After the morning sunrise, the solar radiation intensity gradually increases, and the output of the solar cell also increases. When the output power required for the operation of the grid tie inverter is reached, the grid tie inverter automatically starts to operate. After entering the operation, the solar power inverter monitors the output of the solar cell module at all times. As long as the output power of the solar cell module is greater than the output power required for the operation of the solar power inverter, the solar power inverter continues to operate until sunset stops, even in rainy days. The solar power inverter can also operate. When the output of the solar cell module becomes smaller and the solar power inverter output approaches 0, the inverter forms a standby state.
