Basically you are right. So it is ground then first postive than second postive and so on. the whole group of wires attach to the 6th postive Here is a picture of it hooked up to my testing battery

Check your battery setting number 5 make sure it is "USE" and not "US2" . I accidentally set US2 on one of my growatts and could not get to full charge. Thought i had a lemon. Also IMO float and charge may be too high. I like Andy's thinking of 27.6 for charge and 26.8 for float. This is...

My pleasure. Good luck.

Thanks makes sense. I will change it. Thanks for the help.

Hello guys My battery capacity monitor indicator shows discharging but the indicator for charging does not come on (little triangle point up) any ideas

I think you are correct the charge current is going to the other neg post the batteries are wired in parallel. So do I need to connect to same neg post as the shunt to make it work? The shunt is not reversed and yes I was charging.
