Component Configuration for AC/DC Bus System
The components for the AC/DC bus system were configured in a standard way, as
seen in Figure 1: an array of photovoltaic module is connected to the battery via a DC
bus. An AC bus connects the loads (which are AC) and the genset output. Between these
two buses energy flows by way of an inverter and a rectifier. When the genset is not on,
the load on the AC bus is powered by energy transferred from the DC bus across the
inverter. When the genset is on, it powers the load fully and the rectifier transfers power
to the DC bus as demanded by the charge controller.
