DC and AC Wiring for Multiple Inverters
DC and AC wiring for multiple inverters is illustrated in Figure 3-10.
If there will be more than one PV array, label the positive and negative wire pairs
appropriately (for example: PV1 POS, PV1 NEG, PV1 GND, PV2 POS, etc.).
If required by the AHJ, a DC grounding conductor may be connected to each
inverter’s ground bar. One inverter will connect to a common grounding
conductor. The other inverters will use tap connectors. Connection is then made to
the DC or AC grounding electrode as per NEC 690.47.
Ensure all connections are correctly wired and properly torqued to a maximum
16 in-lb (1.8 Nm).
