Phoenix inverter zero load negative value

My 24/1200 inverter shows an output current value of -0.7A in VRM. I know that the device is not accurate but that 160W fault throws the DC draw way off. If I turn of “Has DC system” in Venus OS on my pi I loose the numbers for Consumption in VRM so that isn’t a way I want to go. Would it be possible to specify a fixed offset in VRM to correct the imprecise measurement of the inverter? So that -0.7A is 0 and 0 is +0.7A? That would at least get rid of the major error whenever the inverter isn’t supplying any current.

System: SmartSolar 100/20, SmartShunt, Phoenix 24/1200. All connected with VE.Direct-USB cables to a Raspberry Pi Venus OS.

Is the Phoenix on pr off at this point?

It may be in AES search mode hence the usage spikes.

Don't forget in the on position the unit does consume a bit of power to keep its electronics alive, and any other device like the GX in the system will be counted as well as part of its self consumption value.
