Fall sunlight cut my battery charge

now everyones heading into fall here in Virginia, and my solar output’s definitely taking a hit with the shorter days. I’ve noticed my battery doesn’t reach full charge as often, especially on cloudy mornings. I’m trying to decide whether to switch charging priority to the grid during off-peak hours or just let the battery top off naturally during the day. What’s everyone else doing around this time of year? Do you tweak your charge/discharge schedule, or just let the system handle it automatically? I’m trying to balance savings with reliability for those random outages we still get around here.
 
that’s normal this time of year like shorter days and lower sun angles cut your generation way more than people expect. I usually switch to partial grid charging overnight to make sure the battery’s topped off for early morning loads. It costs a bit more, but it’s worth it when outages hit before noon.
 
My charge barely hits 90% these days. I’ve been debating if I should just schedule a top-up at night, but I’m scared of bumping the bill too much. Still figuring out what works best.

I have a strategy for this. to maximize the use of available solar power, I schedule high energy consumption tasks for the middle of the day when solar output is at its peak
