Due to not registering CoCT switched me off with out warning, me being an hardass just went on and ran off grid with 3-4 months between mid feb to mid early june.
In that time there was 3 very bad solar days i ran a 1kw gennie for a few hours, the later the year the more efficient we had to be, ie shorter showers, less high usage appliances and some days we had to gas cook water and use a retrofit camping shower with a 12v pump. Changed from 3kw to 2kw geyser element
Also check your fridge if it has a holiday mode, i went from 2.4kwh per day to 1.8, in winter its now down to 1.3kwh. I also installed temp probes to monitor and can switch off the fridge for 4 to 5 hours in the morning, on for an hour then off again and saved a few watts like that on bad days.
We where also with out water the other day for just over a day, removed the non return valve, closed the mains tap and enjoyed a hot shower, we have an RO anyways for drinking water. (Rain water tank and RO waste water, feeds toilets)
So my 2c, get a genny 2nd hand, or a few solar panels you can lay on the lawn for the next time, coct dont fly their drones every day!
