I assume,, he has a deficit during the day using more power from batteries than is generated, and gets the batteries fully charged overnight ?
That was the concept. I’m actually finding that I charge the batteries slowly during 5-6 hours of the day due to all the solar I have. However, from about 5pm until 8pm I’m loosing my solar and starting to drain batteries at around 40+ah. Then as we retire to the bedroom, I shut down one AC but the bedroom ac runs until about 11pm until temp drop into the low 90s ... seriously it can still be in the 90s at 1am.
Around 3am the power consumption starts to equalize with power I’m receiving from shore power and I start to charge the batteries. I really dream about 50amp RV service or better yet cooler temps but need to finish up a few projects before I can move the beast.
If you guys want to see my setup, search YouTube for rvexodus. I have a series on lithium and solar. Catch episodes 8 or 9. I have since added a second victron. Just haven’t published the video.
Anyhow, the crack a window / turn on a fan makes sense as long as it’s not to the point you are pumping out more cold air and pulling in hotter air. There seems to be a balance. I’ll have to see how much I can improve things. I was excited about 5 deg. It is counter intuitive to open a window when running an AC though :)
Someone asked about humidity. We are around 25% with outside being around 10%. Seems about right.
