So my worst production day to date was 11/24. I generated a mere 2.7 kWh all day which is pretty bad when my high in October was over 90 kWh for a single day.
I have used 80 kWh of electricity this day and I still managed to stay on battery all day long with a total battery discharge of 28.4kWh.
I am running 5 oil filled space heaters at night in the bedrooms and various places and I charge my EV at night as well. I used 18 kWh of electricity to the space heaters on 11/24 and 18 kWh for the EV charger so my regular household power usage is only 44 kWh which comes out roughly 1.8kW constant usage which would mean I'd use, on average 25.6 kWh during the 7AM to 9PM window which is pretty close to the 28.4kWh I actually used.
Now the fact that this was Thanksgiving there was a lot of cooking and laundry running that day 2.5 kWh of oven use, 1.2 kWh of cooktop, 5 kWh of dryer, and even with all this I only used 0.5 kWh of grid power right before 5PM as I don't let by battery drop below 50% before 5PM and it ran down to 50% by 4:45 so I was on grid power for 15 minutes before I let it use battery again which lasted until 9PM as it dropped from 50% to 25% in those 4 heavy use hours of the evening. So the worst day so far cost me $0.15 to get through.
The only saving grace is that the temperature is mild so I ran no heat for the day at all, I have gas so I'd still use no electricity but the space heaters at night save me a TON of money on gas.
On my October bill I got a -$22 bill as I exported a ton of electricity during the day and used none, but I did use over 1,400 kWh during the night hours which were absolutely free. November won't be as good as with the limited sun hours we've been having I have not exported nowhere near as much as I did in October, I only did about half of October's export but thanks to the free nights I still managed to pay nothing for electricity.
My battery is 38 kWh and I never let it drop below 25% unless it's an emergency power outage situation.
