  • I was looking at my utilization but i dontk now if this is right

    I have grid tied system 9.1kw fed into my sub panel then i have the cost adapter in the main 200amp panel.

    will the panel pickup reverse flow or will it only go one direction.

    From the utilization comparing it to my grid system output it doesnt seem like it always picks it up. I produce little over 52000w per day which equates to 52kw I use on avg maybe 60 on high day buy in current cost i am seeing utilization of over that amount and it doesnt match up to my utility bill by far.

    My experience on a 100 amp panel is that the CC reads low by around 12%.

    Some of the error is due to the CC assuming the voltage is constant at 120VAC (in the US). I suspect part of the remaining error is installation specific and perhaps accuracy of the current measuring device itself.
