Question Batteries disappeared overnight?

I have 6 lifepower4 V2 batteries, powering two 12,000 XP in parallel.

last night when I went to bed all six batteries were showing up and we had 40 percent SOC. this morning, my state of charge was jumping all over the place and I noticed that it kept switching between four or five batteries...

is this normal when the batteries get low?

as I'm typing this. my state of charge has dropped to 14%. Even though my inverter is pushing in 4,000watts into the battery, and I started at 18% this morning. what is going on? Is the BMS bringing batteries online and offline to balance them, or is something else wrong?

 

thanks!

The batteries reappeared and it's at 25 percent now, but I don't know how to get it to stop using grid bypass. I have it set to only do grid bypass at 15 percent SOC. I'm not sure why it is still using the grid, when I have plenty of solar. It seems stuck in bypass mode. 

also noting that it is impossible to set the start  and end SOC for AC on the Android app. It seems the time and voltage drop downs might be reversed. I had everything set up nicely then when I went into the app to check the AC charge settings it was all blank, and when I changed the drop down from time to SOC it reset everything...

but, it should not be using the grid right now as far as I can tell. what settings do I need to look at to make sure that this is not using the grid when I have 25% battery? it should only use the grid when the battery drops below 15% per the settings I have. 

The notice is for low voltage, which is no longer the case, but there's no way to clear that in the app that I can find... Is it stuck in the state because of the low voltage warning? do I need to manually turn off the grid breaker to get it to go back to its normal operation?

What is your inverter's serial number or station name? I can take a look at it for you. For the Batteries SOC, you can Top balance them. Charging them to 57V. You can also separate each battery and measure the voltage to make sure they are all pretty close to the same voltage.
