DC Wiring

Grounding Series-stacked Inverters

To ground series-stacked inverters:

1.Connect the ground bond in the DC disconnect between the inverters and the batteries to the primary grounding electrode, in accordance with local and national electrical codes.

2.Connect an appropriately sized ground wire from the chassis bonding ground lug on the L1 inverter DC end to the ground bond inside the DC disconnect.

3.Connect a second appropriately sized ground wire from the chassis bonding ground lug on the L2 inverter DC end to a different terminal in the ground bond inside the DC disconnect.
