BMV 712 to inverter connection

I have a bmv 712 with 500a shunt. Can I connect the negative cable of my 2000w inverter to the shunt to measure usage?

Yes you can. I am assuming you have a 12v system. A basic calculation example below. If it is 24v the system amperage draw is half so even less of a load on the shunt.

12v x 500A is 6000W - your 2000 watts even at 100% overload will not max it out in any way.

Hi, did you manage to fix that. My phoenix inverter is just arrived, causing the same question.


Many thanks,

Thomas

Same answer, yes, as long as it's the DC negative.
