Error 203 and 204 of iEM3350 (Non 4 Quadrant Meters in a Photovoltaic System)

[Asif_Khan]

If several meters of reference A9MEM3350 are throwing errors 203/204 which are being used in photovoltaic systems. It is understandable, that this problem is caused by a wiring issue and phase sequence issue.  *(Assume no config, phase and wiring issue)

Lets say these meters are not 4 quadrant meters, so they would not be measuring imported-exported energy. Is it a suitable choice then in a sense that it would work in this kind of setup (photovoltaic generation) at all or no and might be causing these errors?

Will these two errors (203/204) could be caused by the fact that sometimes the current might be circulating backwards on the CT, due to the photovoltaic production and causing these errors?

I will really appreciate any comments in this matter to clear up these doubts.

Thank You!

Yours,

Hello @Asif_Khan ,

203 - phase sequence reversed is only a voltage thing, the phase angle of current does not apply.

204 - Yes if current is flowing from load to line, yes you would see this error code.
