Introduction
Inverters should be protected by circuit breakers. This document describes how to
determine which circuit breaker to use in three phase commercial installations.
Using Transformers in Commercial Three Phase
Inverter Installations
Using transformers in a commercial installation is optional. In most cases a transformer
is used to connect the installation to the medium voltage power grid. The following
figure illustrates a typical transformer and commercial three phase inverter installation
topology.
