A solar power system consists of several components including solar charge controllers, solar panels, batteries, inverters and electrical devices. Inverters can be divided into various categories depending on their operation and application, including self-exciting oscillator inverters, step wave superposition inverters and pulse width modulation inverters. Additionally, inverters are classified as grid-tied or off-grid inverters depending on their connection to the power grid or their use in off-grid systems. According to the type of semiconductor components used in inverters, there are transistor inverters, thyristor inverters and turn-off thyristor inverters. The type of main switching device in an inverter can also vary and includes thyristors, transistors, field effect transistors and insulated gate bipolar transistors (IGBTs).
Protective functions of solar inverters:
Over-voltage/under-voltage protection: When the input voltage exceeds 130% of the rated voltage, the inverter should activate protection mechanisms and indicate this. At the same time, when the input voltage is less than 85% of the nominal voltage, the inverter should activate protection mechanisms and indicate this.
Overcurrent protection: When the operating current exceeds 150% of the rated current, the inverter should automatically protect. The inverter overcurrent protection should ensure that it reacts immediately when there is a short circuit or the allowable current value is exceeded to prevent damage caused by current surges.
Short-circuit protection: The response time of the short-circuit protection in the inverter should not exceed 0.5 seconds.
Surge protection: The inverter should have surge protection.
Overheating protection: In addition, the inverter should have overvoltage protection devices to protect the connected devices from overvoltage damage.
A powerful inverter should have comprehensive protection functions and mechanisms to respond to various unusual situations during operation. This protects both the inverter itself and other parts of the system from damage.
