Automation tasks underway
I have the following automation tasks underway, in various stages of completion: If there is a suitably inexpensive timeslot overnight, use it to top up the batteries to 100%. Using this, instead of solar, will allow more solar to be exported at 15p/kWh. Inexpensive slots during sunlight hours are not as useful because I can't export at the same time as using electricity from the grid. If there is not a suitably inexpensive timeslot overnight, top up the batteries from the grid during the period coming up to peak time (which is usually fairly reasonably priced). Make sure any battery charging from the grid is definitely off before the 4pm-7pm peak rate starts. When the electricity price goes negative, boost the hot water temperature using the heat pump and immersion heater. This is a way of benefitting from being PAID to use electricity and storing a little of it in the form of hot water. Change the colour of a lamp in the kitchen to reflect the current electricity...
