Experimental current waveforms for a system with nine parallel inverters: a APF-PLL (power of a single inverter = 2.37 kW; total power of nine inverters = 21.33 kW); b SOGI-PLL (power of a single inverter = 2.6 kW; total power of nine inverters = 23.4 kW)
Parallel inverters offer heightened power output, increased efficiency, and redundancy. For example, connecting two inverters with a combined capacity of 4kVA provides a power capacity of 8kVA in parallel. This redundancy ensures uninterrupted power supply and flexibility in load management. 13.
For instance, connecting two 3kVA inverters in parallel results in a combined capacity of 6kVA. In series, inverters increase voltage but not capacity. Understanding this difference is crucial for designing systems with specific power requirements. Running inverters in parallel offers increased power output and improved load handling capabilities.
