Hi all,
Got a recently installed PW2 plus 3.2kw solar array. I’m on a time of use tarriff with Octopus Energy with a cheap rate between 23:30 and 05:30 (7.5p Vs 40.7p), I’m located in the UK.
I’m trying to get my head around what the expected behaviour from the powerwall when in time based charging mode.
Last night the powerwall only charged itself to 73%. It then stopped and by the time I woke up and checked the system it was down to approx 55% as it’s running the house from 05:30.
Todays weather is strongly sunny.
Is the PW even in time based mode trying to adjust its charge for the weather? Ie expecting good solar output so will not charge as much?
Or was it some kind of mistake or error? It was quite cold last night, I considered perhaps this caused a problem, although it still had plenty of time to charge at a reduced rate.
At the moment I am trying to ensure no house peak electricity usage by load shifting, hence using time mode. In the summer I expect to switch to Self Powered mode which I presume is broadly the opposite Ie PW chargers in the day, and discharges at night.
