Cold mornings and cloud cover cutting into your output too?

The days are getting shorter here in Idaho, and my solar setup’s home battery is starting to feel the difference. During summer, it easily handled the whole house and kept the battery topped off, but lately I’m pulling from the grid more often at night. The panels just don’t seem to keep up with the morning frost and those long cloudy afternoons. How’s everyone else holding up? Are your systems still covering most of the load, or have you had to start rationing battery use? wondering if this is just normal for the season... or if I should like tweak my inverter settings to prioritize charging earlier in the day.
 
Cloudy days and cold temps are a double hit like panel efficiency actually improves in cold weather, but there’s just not enough sunlight to take advantage of it. Some users here have added small schedule tweaks like running heavier loads midday instead of evening. Do you track your daily kWh trend to see how much your output’s dropped since summer?
 
Honestly this is just winter being winter. The panels hate cold mornings and grey skies, and the battery ends up paying for it. If your system was sized tight for summer, it’s going to feel even tighter now. Tweaking the inverter to grab charge early helped me more than anything else.
