How many batteries

Loops like I only have an AC input voltage between 65-149 & 95-140. I am set at 65-140. There is a max utility charging current. Default is at 30a
 
I am back again, issue not resolved but I have been looking into the info you passed on. I never gave any thought into sizing my generator for the battery bank size and I am sure I am not alone in that. If you don't mind unpacking what you shared about the charging rate of the 100ah cells and the amps. I am sure this will be helpful to many who are new at this like me. Thanks

Confirm my dumb moment...

Yesterday the grid was down for around 7 hours, only the 3rd time this month... Batteries were down to ~51V. (snow and no sun) I hooked the generator (5.5kw Generac gas) up to the TP6048 (LVX6048) utility input and was able to start charging the batteries after adjusting the time settings for...

Edit - you may have to add a load to the generator to get the inverter to accept the power.
 
When the generator is running, does the Inverter show this icon?

Looking through the manual, it looks like it might need all three connections for split-phase to work as a charger, though it's not 100% clear. I'm guessing your generator doesn't output split-phase?
 
@Crowz has this inverter if I’m not mistaken.
Hopefully between him and @42OhmsPA (who also has this inverter, again if I’m not misthinking) hopefully you can get some solid guidance.

As stated above. No such thing as too many batteries. Similarly, while a generator may be “undersized” it should still provide power providing the demand isn’t exceeding output capacity.

You mention using it before without the 4th battery. Is that the only change that took place? Is it an inverter generator?

Yep, last time I used it I had only 2 batteries.
 
On my tp6048 I only have one battery. I normally see about 36 amps or less being pulled from it when its running on the battery. Mine is setup basically as a ups for now since one battery isn't enough to go full time running on the battery :)

I calculated for my usage I need 4 batteries to get thru the night if the pv handles my needs during the day.
6 batteries would be ideal to get me thru anything I would likely run into.

When you mentioned add a load to the generator, you mean plug something in and run?
