Shelly monitoring

#1

Post by ecogeorge »

Anyone monitoring with Shelly clamps and App ?
I have 2 clamps, one monitors solar generation on it's dedicated circuit the other monitors the mains incoming supply.
They both can sense a change in direction of flow of electriciy but are always the wrong way around.
The solar generation always shows as a minus and the incoming also.
From the attached screenshot I am generating 998w from solar and am exporting 946w back up the grid but it confuses the hell out of me working out which way it's all going ?
Any thoughts?

Just turned the solar generation sensor 180 degrees , bingo - instead of using 15w panels are now generating 15w . Thank you. Will swop incoming sensor tomorrow.
