Pause charge schedule for agile

matlynd

A feature request please. Could we please get a pause charge schedule for agile based on a export price parameter?

The logic behind this is as follows:

If there's charge slots in the day that are cheaper than my export costs (< 15p in my case), then i want my solar to go to export and then charge my battery on <15p electric.

an example:
cheap day (cheap slots in the afternoon):
Pause charging 07:00 to 13:30 (excess solar goes to grid rather than battery @ 15p/KWh)
Charge 13:30 - 15:00 on cheap agile slots (_10p/ KWh)

Expensive day (all daytime slots > 15p)
Dont pause charging, and charge from solar as no slots meet the defined price threshold (sayt 14p to account for losses). Export will then only happen after batteries are full
Agile charge slots likely to be skipped or will just top up battery if not fully charged by solar

This will maximise export revenue when its cheaper to buy than to use solar. I'm currently doing this manually through the Giveneergy portal, but it would be great to be able to automate it along side the agile charging. Currently if i dont adjust the pause charge in the GE portal correctly, it blocks the WW charge command. If i fail to remove the pause charge schedule in GE on expensive days, then i end up buying at more than i'm selling.

Pause charging 07:00 to 13:30 (excess solar goes to grid rather than battery @ 15p/KWh)
Charge 13:30 - 15:00 on cheap agile slots (10p/ KWh)

If you left this as is, would your battery not be filled up from solar and you'd instead export solar later in the day at 15p?

admin yes, but i'd rather charge on the cheap grid 10pKWh electricity rather than using my generated solar electricity, as that is worth more to me if exported.

If i need to charge 10KWh on my battery... that would cost me £1.00 on cheap agile slots (@10p). If i used solar to do it, that same electricity is worth £1.50 to me if i export. Thats 50p effectively thrown away if i use solar to charge. Same reason i charge overnight to 100% if the price is sub 15p rather than just letting solar do it the next day.

It would only add benefit where there are slots during the day that are cheaper than the export price

admin This is an inefficiency in the Grid system at the moment, where typical solar and battery owners, on sunny days, charge up their batteries in the morning, then dump their excess production on the grid in the afternoon.

It would much more efficient if batteries were charged up at the cheapest times with more exporting at higher rates, but this might take action by the government (so not so likely). Perhaps some interested parties such as Octopus Energy, Enphase and / or GivEnergy will get together and think of something.
