Phoenix Inverter 12/1200 VE.Direct does not show AC out

I can read all the values that the datasheet says is available, like AC OUT Volts is what I expect at about 120.02v. But AC OUT Current (AC_OUT_I) just shows -1 or 0 for me.

I have some experience using VE.direct USB cable with a raspberry pi to read the metrics from the serial port for a BMV so I'm pretty sure I'm doing the basics right.

Example output, includes model and firmware if anyone is familiar with these:


['Checksum', '\xd2']
['PID', '0xA279']
['FW', '0114
['MODE', '2']
['CS', '9']
['AC_OUT_V', '12001']
['AC_OUT_I', '-1']
['V', '13541']
['AR', '0']
['WARN', '0']

Oh! I didn't realize my AC load was so low (with just cell modem and wifi powered). I used a kill-a-watt, and plugged in a laptop and got some readings that made sense.
