Hi everyone,
I've attached the wiring diagram for my Samlex EVO 4248. The Samlex manual recommends (and implies) that the grounding lug on the chassis is for the DC side and needs to be grounded to earth separately from the AC side.
However, looking at the schematic, the grounding lug and both AC grounds are all connected to the chassis. In addition, they are all eventually grounded to the same grounding rod. So why does it matter if the chassis lug has a ground connected or not?
And secondarily... why does Samlex also recommend connecting the battery negative to the same ground as well? I don't see anyone here doing that for off-grid systems...
