In the U.S., the National Electrical Code (NEC) provides guidelines for identifying wires in three-phase systems. Using 480V three-phase power provides major advantages for industrial operations. Three-phase systems are more efficient than single-phase systems because they can deliver more power without increasing the amount of current.
This type of inverter is commonly used in commercial and industrial solar power installations where three-phase power is required to run heavy machinery and equipment efficiently. Use Cirkit Designer to design, explore, and prototype these projects online. Some projects support real-time simulation.
1. With up to three 7 kVA inverters per phase, the 3-phase system sizes are 21, 42 or 64 kVA. In the example in Figure 2 with a 60 kVA source and load, there is approximately 87 Aac per phase. This means that at least two inverters per phase would be required as each inverter can pass through up to 50 amps.
Solution A single 3-phase autotransformer can be used to step down the incoming 277V per phase (480V 3-phase) to 230V per phase for the GS7048E AC inputs. The 230V inverter outputs are then stepped up through another 3-phase autotransformer to 277V per phase (480V 3-phase).
