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.
