Figure 2-21 On-Grid Application – Backup System using a Single Inverter
NOTES:
1. Always refer to your local electric codes for proper
wiring instructions.
2. For purposes of this illustration, the ground for the
AC generator is run through the inverter.
3. Separate grounding runs are shown in this
illustration to demonstrate a single point ground.
4. If using a PC to monitor the system, the Xantrex
ICA is required. If using a PC to monitor from off-
site, an external modem is required at the inverter
site.
5. Ensure all the DC negatives in the system are
bonded to earth ground in only one place (single
point bond). If you are using a PVGFP, allow this
single “DC Negative to earth ground bond” to be
provided through the PVGVP.
6. If this is not a separately derived system (per the
NEC), the AC neutrals should be bonded to earth
ground in only one place.
