Commercial grid tie inverter manufacturers china tells you that grid-connected inverter architectures use newer high-frequency transformers, traditional line-frequency transformers, or transformerless inverter architectures. Commercial grid tie inverter manufacturers china tells you that the high-frequency transformer does not directly provide 120 V or 240 V AC power, but has a computer-controlled multi-step program that converts the power into high-frequency AC, then converts it to DC, and finally converts it again The voltage and frequency required for the power supply.

Commercial grid tie inverter manufacturers china tells you that transformerless inverters are lighter and more efficient than inverters with transformers. However, because there is no electrical isolation between the DC circuit and the AC circuit, the short-circuit current at the DC terminal will directly jump into the main circuit when there is a fault.
The Commercial grid tie inverter manufacturers china tells you that there needs to be a residual current or ground circuit to detect abnormal short-circuit conditions, and an insulation test is also performed to confirm the separation between the DC circuit and the AC circuit.
Through the above introduction and analysis of Commercial grid tie inverter manufacturers china, hope it helps you.
