The SOLECTRIA XGI 1000
TM
is a 480VAC, 60Hz, 3-phase grid tied inverter with clockwise phase rotation. The inverter will
not operate when installed to any other grid voltage or frequency. This section includes important information regarding
the AC grid connection, wiring requirements, and installation instructions.
Transformer Configurations
CAUTION
Improper Transformer Configuration: Inverter will not run and may have hazardous current. Connect transformer in
specified configurations only (see Figure 3-12).
NOTICE !
480 VAC, 60Hz, Grid Grounded Wye ONLY: The inverter is only rated for 480 VAC, 60Hz, 3-Phase grounded Wye.
Installing the inverter on any other electrical grid will damage the inverter and void the warranty.
INFO
✔
Grid Mismatch: If the grid does not match the requirements of the inverter, the inverter will not start.
Check with your local electric utility before selecting a grid profile. The system must comply with National Electrical
Code ANSI/NFPA 70 and with all local rules and safety regulations before the inverter can be operated.
The inverter must be connected to a 480VAC, 60Hz, grounded Wye electrical grid. If the installation location does not
meet these requirements, an isolation transformer may be used.
The inverter side of the transformer must have a grounded Wye configuration. See Figure 3-12 for approved transformer
configurations, all other configurations are not permitted. Figure 3-13 shows examples of transformers that are not
acceptable.
