1.3 Product Overview
 Basic information
The Digiwatts inverter is used to convert DC power generated by the PV arrays
into stable AC power for output to the utility grid. The Digiwatts system is a
transformerless inverter and performs this conversion in a very efficient way,
without moving components, using only solid state power electronic devices.
It is a crucial unit in the small-scale PV power system.
An example of basic PV power system components is shown in the Figure 1-1.
