Grounding to frame

[Ninjakitty]

Just double checking before I finish my solar and electrical wiring: I can run my inverter, charge controller, and battery grounds to the negative busbar and then run a ground to the frame from there?

In the picture, I plan to run 4/0 cable to the frame to ground. I can run all my grounds and negatives to that black busbar?

I saw this earlier but had to check so I could comment.

The inverter should ground only with the alt current source or shorepower.
The rest can ground with the frame from what I know to be true.


Nice work on the cables. Do you have a crimper or rent one? That is the only way for those lugs to go on and stay on.

Are the lugs copper or aluminum? Not really a good mix to go copper to aluminum and be sure to use Noalox if you happen to.

Hey John, as always, thanks for the help.

The inverter is the Aims 3000 inverter/charger with transfer switch. I will make sure to keep the 120 side off of the busbars and only grounded from power source.

On the DC side of the inverter, there is a grounding lug. Does this ground need it's own separate grounding? I can't see how it would ground to the source. I'll also read the manual again! [emoji106]

I borrowed a hammer crimper and beat the lugs with a 5 lb sledge. I used the heat shrink that has the glue inside of it.

The lugs with on the 4/0 are all copper and the 4/0 is copper. I'll check out which busbars I bought to make sure they aren't aluminum and I'll double check the lugs on the 4 ga.
