The PV generator is tied to the DC bus via the DC interface section. The
embedded control card manages the transfer of power between the PV
generator and the utility grid.
Heater Fans
The heater fans provide supplementary heat to Xantrex GT500 units installed in
particularly cold areas. These heater fans help the Xantrex GT500 remain above
the low temperature cut-off point and enable the Xantrex GT500 to begin
operation when the external ambient temperature is below the rated operating
temperature. In addition to aiding startup in low temperatures, the heater fans run
all night—if the hygrostat setpoint is reached—to help prevent condensation
inside the Xantrex GT500. For the location and photographs of the heater fans on
the inverter assembly, see Figure 1-5 on page 1–8 and Figure 1-6 below. For the
location and photographs of the heater fans on the transformer assembly, see
Figure 1-3 on page 1–6 and Figure 1-7 below.
