Technical FAQs 4

What are the input voltage technical parameters in a photovoltaic grid-tie inverter?

In the photovoltaic grid-tie inverter, there are many input voltage technical parameters: Maximum DC input voltage, MPPT operating voltage range, full-load voltage range, start-up voltage, rated input voltage and so on. These parameters have their own focus and all of them are useful. Maximum DC input voltage

What is the control design of a grid connected inverter?

The control design of this type of inverter may be challenging as several algorithms are required to run the inverter. This reference design uses the C2000 microcontroller (MCU) family of devices to implement control of a grid connected inverter with output current control.

Why does a string inverter have a 230V output?

The reason for this starts from the principle of the power inverter. For the DC-DC-BOOST circuit of the string inverter, the DC voltage needs to be boosted and stabilized to a certain value (this is called the DC bus voltage) before it can be converted to AC power. As to the 230V output, its DC bus voltage should be about 360V.

How many control levels does a grid-side inverter have?

The strategy consists of 2 coordinated control levels: 1. AC Level Control Manages the grid-side inverter to provide positive and negative sequence voltage support while limiting overcurrent and DC-link voltage oscillation.
