Inverter Grounding
Requirement
The inverter/charger should be connected to a grounded, permanent
wiring system with the AC and DC grounds commonly bonded to each
other and should be bonded to the grounding system at only one point in
the system. See
“Bonding the Grounding System” on page 2–10
for
additional information.
Conductor size
The size for the grounding conductor is usually based on the size of the
circuit breaker in the DC system.
Table 2-1
provides battery DC
disconnect sizes and minimum wire sizes of copper ground wires for
grounding systems.
It is recommended that the size and gauge of grounding wire should be
more than the NEC/CEC minimum requirements when installing power
sources such as inverter/chargers or generators.
WARNING: Shock Hazard
Attach the ground lead BEFORE attaching any AC or DC power connections.
Table 2-1

DC Disconnect Sizes per NEC

Note:
Field experience has demonstrated that long distances or high
impedance grounds can cause equipment malfunction or damage.
WARNING: Explosion Hazard
Never use a gas pipe or gas line for grounding purposes. The inverter is a power
source and it is intended to be grounded at the service/main ground rod.
