Gauteng Who is not using grid....

The combination of these two factors means that the total demand and what I use from PV has dropped, but what I draw from the grid has stayed pretty constant, and so grid power consumed as a % of power consumed by the house is rising. This makes me grumpy.

Strange, since I installed my system from an average 22 KW/h a day from grid I managed to reduce it to about 5 Kw/h see dashboard of my last 90 days.

also @Bobster., via the extension lead the monetary grid amount was effectively nil, to me, but we were using 2-3kWh extra per night, that the battery would not have had capacity for... now if we wanted a prepaid meter from Eksdom, which they refused to put in when asked a few years ago, we'd be looking at R 8.00 per unit/kWh, not an option and mark this text, this is what will be the target unit price elsewhere, I suspect, I've got 16 x 304Ah cells coming, hopefully before the weekend (that aught to keep me out of mischief for a day or 2) and once that is added to the existing 8k2W battery, we should be fine overnight, without manually cycling various loads...

Certainly we've gone from over 30kWh/day, 5 years ago, to 20-24kWh/day these days, the consumption will go up again, but all of it will be solar sourced and battery supported after dark...

Lovely graphs. Where are you sourcing the cloud cover and load shedding information?

@p_i The load shedding schedule is linked to the ESP app, the cloud cover from our nearest weather station, it's quite accurate.

Not a productive day in Randburg. On a good day my battery is charged by 10:30. Today it hasn't seen more than 80% SOC.

  that is hell of expensive for electricity. Even good old COJ, not knowing for having the most attractive electricity prices, is charging R2 and some change.

My bad. I meant what I've been drawing from the grid since I first converted to PV.

At conversion time I was using 13kWh total and about 1.2 from the grid on a good day (I know... it's wastrels like me that bump load shedding up a stage).

These days I'm using 10 to 11 total, but still about 1.2 from the grid. 

That's because of the inverter - I think it's the way it's designed. But I suppose I could try asking Goodwe support about this. They'll probably tell me to use some time-based rule.

For me today produced 60% of a full sunshine day so around my daily needs. Good enough for me.

Sunday I expect no sun so that would mean grid use for the day for about 80% + of our needs. Depends as usual how busy the kitchen will be

LS today from 16h.
