is it a small amount of current or a large amount?

if it is a small amount, say less than an amp, it is probably just noise on the current sensing circuit.

The only a Bluetooth 500a shunt, and an Outback fm60/150. Shunt measuring total and midpoint voltage. That’s all dc, so the AC out values are

You're not the first one to post this issue, but I have not seen a response by victron. I also get the negative output on L2 when in inverter mode or single phase input. My system shows exactly double the negative output (I have parallel MP2's) six hundred fifty something negative amps on the L2 output. I think there are probably a lot of people that have the same issue but they don't know it because you only see it if you are looking at the output thru node red, mqtt, or victron connect via a MK3. It doesn't appear on the GUI except for in the device list.

Edit: this is on the MP2 2x120, all the posts I have seen is for the same unit. I have seen several more posts about this issue on a few Facebook groups.

I have the same issue with ac out L2 showing -655 amps. Smart dongle reads 0 amps L2 out. Did you find a solution?
