This is an updated version of our original video. In our original video, we connected the negative cable of the inverter directly to the ground. We were advised that the more correct method is to connect that negative cable to the shunt, and not to the ground. Basically, everything should be connected to the "system minus" side of the shunt, and then the other side, "battery minus" is connected directly to the black neg cable going directly to the lithium battery.
We did not see any difference when turning on the app, so both methods probably works, but this is the more correct method.
