Self-used ratio
My understanding of “self-used ratio” is the % of power used of what Solar produced.
My setup: (I use very little power as we are 2 people in the house and my Geyser is on separate solar)
I have a Inge 5Kw inverter with 5 x 415w panels (on a normal day I get around 1,7Kw/h)
My CT clamp is on the main incoming from Eskom with the following settings:
So from 21h00 (battery is full)at night my house go on Battery and from about 06h30 / 07h00 the sun start charging the battery and supply power to the essential load as well and on a normal day the battery (5,12kw/h) is fully charged around 10/10h30. Up to 17h00 the Sun and Batt supply my household and if Batt is not full Eskom will make sure it is full by 17H55
This is a reading 19/10/2022 @ 11h32, we have some clouds
so battery charging take longer
O
So from the screen dumps it can be seen that the Self-used Ration is 36,73%. Surely this cannot be correct as at the time (of pictures) I have used all the Solar production for essential load and battery charge – none from Eskom. What am I missing?
