That is interesting. I always switch off smart charging during these "power hours" because I don't want the car charging at 7.4kW while Octopus are monitoring it.
I'm charging the IOG EV controlled one at 10A and SWMBO EV at 32A.
With 2 mins to go before the power-hour finished, I stopped the car charging, switched to 6A, turned smart charging on, and asked for a charge schedule. So at least the 2nd half will be at double-bubble...
It should be near quadruple bubble, x3.7 on my tariff if I pay 7p but get 26p rebate for every kWh used.
16.9kW PV > 108MWh generated
Ripple 6.6kW Wind + 4.5kW PV > 24MWh generated
5 Other RE Coop's
105kWh EV storage
60kWh Home battery storage
40kWh Thermal storage
GSHP + A2A HP's
Rain water use > 510 m3
The way it seems to work for me (without an EV) is that my bill includes the price of the units at the standard rate (23.57p,) but I get the power hour consumption credited back separately so it effectively costs me nothing. That messes up my spreadsheet though! Of course I re-export as much of it as I can straight away in the next evening peak at 27.33p.
