The higher voltage is due to having lithium battery.
Post #1
LiFePO4 batteries were at 13.6 volts after charging. Next day 13.3.

Now I would not get too focused on using voltage as a guide for state of charge (SOC)
Lifepo4 have a very flat charging curve
13.3 is still a very high state of charge.
Best thing to focus on ... how much power a day do you use
Do you have enough battery power to last you for a few days
are you able to replace that power + a bit more during the day
via the charging methods available to you at the present time.
If solar is the only charge source...
allow extra battery capacity your battery should hold about 3 days
OR add more panels
Solar is a good charge source as long as the sun is shining.. you are adding those sneaky electrons back.
Your
solar charging setting should be set so as soon as charge is removed it is topped back up ... don't drain your battery to 20% and then hope you have enough charging time to get it back to 90-100%
You can add another lifepo4 to your bank at any time ... you don't have to worry about the matching criteria associated with lead acid .
Cost of a bit bigger battery bank sure beats the heck out of electron watching
