Parallel inverter refers to a system configuration that connects multiple inverters together for parallel operation. The main purpose of parallel inverter is to improve the total power output and reliability of the system.

The main functions of parallel inverters are as follows:

Increasing output power: By connecting multiple inverters together and running them in parallel, the output power can be effectively increased. This is particularly important for large photovoltaic power plants or industrial solar systems. By paralleling inverters, the output power of multiple inverters can be stacked to meet the power demand.

Improving system reliability: Connecting inverters can improve the reliability of the entire power system. When one of the inverters malfunctions or requires maintenance, the other inverters can still operate normally to ensure continuous power supply to the system. This redundant design can reduce system downtime, improve system reliability and stability
