Technical FAQs 4

What is an inverter used for?

An inverter is a power electronic device that is not exclusively used for solar PV applications. Its most basic function is to convert DC (direct current) to AC (alternating current). The difference between the two and their specific applications are detailed below:

Does a multilevel inverter work?

Normally, this method works, but in some applications, it creates problems, specifically where we do not require high distortion in the output voltage. The concept of a multilevel inverter (MLI) is a kind of modification of a two-level inverter.

Can a designer use one central inverter?

Designers can use one central inverter as illustrated in Figure 4.1, where all strings are connected to the DC side of the inverter and the single AC output is connected to the utility grid. High DC wiring costs and power loss due to Voltage Drop. Huge size!

What type of Inverter should I buy?

String Inverters – string inverters are the most versatile in terms of power rating, which can range from 1kW to 100kW with much smaller increments. Microinverters – the most common power ratings for microinverters are 250W and 500W which are designed for 1 and 2 PV modules, respectively.
