Without proper protection, an inverter can be damaged by power surges, voltage spikes, and other electrical disturbances. There are several types of protection that can be used to protect inverters: Surge protection: This type of protection is designed to protect the inverter from power surges and voltage spikes.
Inverters equipped with over- and under-voltage protection automatically monitor the input and output voltage levels. If the voltage deviates from the preset safe range, the inverter will either shut down or adjust its output to bring the voltage back within acceptable limits.
By protecting the internal circuitry of the inverter from high voltage spikes, overvoltage protection ensures the longevity and reliable operation of the inverter. This not only extends the life of the inverter but also maintains the efficiency and safety of the entire solar power system.
Undervoltage protection ensures that the inverter operates within safe voltage limits, thereby avoiding potential issues caused by low voltage conditions. Low voltage can be as damaging as high voltage, leading to improper functioning and reduced efficiency of the inverter and connected devices.
Surge protection: This type of protection is designed to protect the inverter from power surges and voltage spikes. Overload protection: This type of protection is designed to protect the inverter from being overloaded. Under-voltage protection: This type of protection is designed to protect the inverter from low voltage.
