sol ark has an odd charging behavior with solar. With TOU, it will obey the voltages you put it to a T but when it starts to solar charge, it charges over the specified voltages. I wonder why they choose that behavior. It's quite annoying for cycling on a daily bases when grid charging.
obeys the settings while charging from the grid.
Here's solar charging. Just odd that they would do that specifically with solar charging.
I was aware from fellow forum members that the voltage needed to be set lower but I wasn't aware this is a solar only issue. Setting the float to 52.2v seems to allow the cells to get to 3.33v.
So this leaves me with a bit of a conundrum when there's a power outage. I can't really let the solar fully charge the batteries in a power outage with the charging voltages set to a low setting for everyday use. Would need a rule for "when grid is down, charge to 55.2v"(56.5v charge) which doesn't seem to be possible.
Or in the current case, rely on equalization. I set equalization to 2 days to see if the sol ark will treat the grid charging as a equalization timer and resets that timer. I hope so... If it does, I should be able to just set days to 0 or 1 day so in blackout scenarios it does equalization.
I ran out of time before TOU kicked in. I'll update if I need to adjust any settings
