^^^ I did not know about the above song by CCR, just listened to it and found the beat similar to that of the song "Proud Mary". I listened to the latter and "Up Around the Bend" in my teenage years.
A morning ritual I have is to go back to the backyard shed to check on the solar battery status, while my coffee is dripping.
For the 2nd morning in a row, the battery still has juice after running the mini-split AC overnight. The weather has cooled, and the temperature is down to the high 70s in the early morning, while the 24-hour average temperature is "only" 85F. The mini-split does not have to work as hard.
There's now plenty of juice left after the minisplit to keep the main fridge going. And yesterday, in the late afternoon, the battery was full and one of the solar charge controllers cut back and went to sleep.
Today, I will try to rewire the water heater back on the solar electric circuit. I had a secondary water heater wired as a dump load for the solar when the battery got full, but it developed a leak, was removed and not replaced. I need to wire an autotransfer switch for the remaining sole water heater.
PS. The easiest way was to leave the upper heating element wired up to the grid, while the lower element is rewired to the off-grid solar power. No transfer switch is needed, and it works better this way too. There's always hot water with the upper element as the backup, while there's 2/3 of the tank for the solar power to heat up during the day.
The above may not work for a big family, but should be fine for us. Will see if we run out of hot water with this arrangement.
