Why did the inverter stop charging,

That is a pace bms btw and since pacebms default balancing only starts at 3.5v you aren't balancing.

I assume it thinks its full? Not sure.

When it was at 99, I just waited for the indicator to stop blinking that it was charging and then just checked the individual cell voltages. It had reported 100% after the green led went off.

What voltage is it charging at?

Correct.

@denmendez65, maybe drop charge amps down from 10 to 5 and float at 56.8V then check balance in the evening and then again in the morning.

Would be difficult to do during the week.

Can only do on weekends. Difficult to get the other to force a charge and between 90 and 100 once it’s full it doesn’t charge.

That might be just a setting on the Omnivolt. Return to grid or something like that setting.

I’ll see what I can do but weekend is the best as I can be there as it gets full.

I suspect a cell is peaking to 3.65V before it gets to 56.8V.

Well I was getting error 64 at some point so you might be right. I just followed the configuration done by others also getting it on Powerforum to make it go away.

What is error 64? Maybe drop it to 56V for this week and re-evaluate on the weekend.
 
My 5kw shows error 64 if i use the default 56.0 it gives you. I had to set mine to 55.8 bulk and 54 float. When the error happens 2 cells shows almost 3.65v the rest still far they all in the 3.4v odd
