We ran all of our aircon units last night when asleep, set at 18c in all rooms. Have kept the ones in unused rooms at 18c and the main one in the open plan dining lounge area at 25c, which has maintained a temperature of 21c in the dining area. Luckily, our net metering spare units have not been taken off us yet, and we still have 150 kwh in our bank.
Today, we consumed a record number of KWH. We have kept our pool heater on during the day, when the solar pump is working, so that the temperature does not drop too much and 10 hours use of the pool heater is getting the temperature back to what it was the day before. Pool temperature this morning 22c and 10 hours later 24c. We will probably lose at least 3c overnight. However, we now know that if the weather is exceptionally cold, to expect a decrease in pool temperature even with the heater on.
During the day today, whilst the pool heater was on, our average consumption per hour was 5.15 KW per hour. Over the 24 hour period the average consumption was 3.48 KW per hour (including the 10 hour period when the pool heater was on) which I think is very impressive for heating the whole house and keeping the pool at a reasonable temperature so that when the weather does improve, we will be able to go back in.
Green Air replaced all of the original air con units with new, LG invertor ones which have a 10 year guarantee on the invertor. They are really quiet and efficient. Last night, again extremely cold, and down to 2c here in Anarita, we used 37.6 kwh from 5pm till 8am this morning, and that included cooking our tea with 4 electric rings on for 30 mins and baking a fruit cake, with the oven on for an hour and a half. Works out at 2.5kw per hour for keeping the house at 18c overnight with 5 aircon units set at 18c whilst we were asleep and one unit running at 25c from 5pm till 11pm.

May I ask how much kW/h you produced yesterday John from your installed photo-voltaic modules in this cold conditions, with only a few clouds at times ? (OK, at my place there were clouds for more than an hour) If I remember Green Air installed you a 5 kWp system with optimizer....
Max. Solar Edge are monitoring our invertor at the moment, so our production figures are inaccurate. That, however, is the advantage of buying from a firm like Green Air. If something goes wrong, they will sort it out immediately. I think it might be a fault with our voltage from EAC on Line 3 but I am sure they will solve it. One neighbour with a 5kwh system, but fewer panels, made 20.64kwh today. (panels not all south facing like ours). On 16th March last year, a similar day sunwise as today, we made 28.83kwh. On 12th March last year, which was completely cloudless, we made 30.51 kwh.
As I said earlier, we are glad we bought from a reputable firm, as the problem with our invertor is being sorted out.
Thank you John for your answer. It was just out of curiosity how much the cold temperatures these days effect the production of electricity from PV.
With only 5 c lunchtime at my place my inverter display reading was amazing and per kWp installed modules I produced 4.5 kW/h that day....
