Array Sizing
To determine the number of photovoltaic panels required for the PV power plant,
use the PV planning tool on the Schneider Electric Web site:
1. Go to www.schneider-electric.com/renewable-energies.
2. Navigate to your specific product page.
3. Click Sizing Tools.
External Disconnects and Overcurrent Protection
In all installations, the installer must provide disconnecting means for the PV
input, AC output, and external auxiliary AC source input (if used) wiring. It is also
the installer's responsibility to determine any external overcurrent protection
needed for these circuits, in accordance with the applicable installation codes,
the currents involved (see Appendix A, “Specifications”), the wiring size used,
and any other system parameters required by the installation codes.
AC overcurrent protection for the utility interconnect (grid-tie) and auxiliary power
input must be provided by the installer as part of the Xantrex GT500’s installation.
Environmental and Site Requirements
The following environmental and site requirements must be met.
Minimum
Clearance
Maintain the following minimum clearance requirements for the Xantrex GT500—
or more if required by local codes for service clearance—for maintenance and
serviceability:
• Front: 1220 mm (48 in.).
• Rear: 305 mm (12 in.).
• Above: 305 mm (12 in.).
• Sides: 0 mm (0 in.).
Temperature and
Air Flow
The inverter is designed to operate in a -20 °C to 50 °C (-4 °F to 122 °F) ambient
environment (with output power derating from 45 °C to 50 °C [113 °F to 122 °F]).
See Table A-1, “Environmental specifications” on page A–2. Direct solar radiation
can raise the internal temperature beyond these specifications causing the
WARNING
HAZARD OF FIRE
The following AC overcurrent protection must be provided by the installer:
• AC output: 900 A maximum
• Auxiliary power input: 20 A maximum
Failure to follow these instructions can result in death or serious injury.
