27.6kWh yesterday.
Car was charging at 6A for most of the day, got 3 loads through the washer, ran the dishwasher twice, and managed to only export 0.6kWh at the expense of using some peak-priced electric when demand outstripped what my inverter could supply.
However today is another day and looks to be a sunny one, washing is done, both cars are charged, I have no idea where to start putting the electric to use.
I seriously struggle to understand what you guys do with all that power! Sure I don’t have a DHW tank to dump it into and I know your arrays are sized for March and October rather than midsummer, but seriously, what do you do with it all?
Big water tank, big EV battery pack, decent size home battery and living North I can easily handle a Storage heater or five on crazy days. Saves wood store depletion which i am happy about. That takes care of most of it.
We can store a max of 208kWh. TBH, after writing that the rest of the use in daily life seems inconsequential.
It's a big house not in a city and we use the EV a lot. That alone swings it in favour of using most available PV power.
I also found that having the larger home battery gave me the confidence to chuck greater volumes of power about knowing that even if I get it wrong a handful of percentage points soc will get us through to the next day. Then the bigger arrays can catch something meaningful even in marginal conditions.
For example we have started today with 18% soc as we charged the loan EV yesterday and HWT at 03.00hrs.
Grey skies at the moment yet 1.4kWh coming in. No worries
.
I can't emphasise enough how I think it important to fight the fight from both ends and run as low cost energy house as possible
. It truly has been the missing spoke in the wheel that generates grid avoidance (truly mangled that last, cant even claim it as a genuine metaphor).
