BSL 51.2v connected to Sunsyk 5Kva inverter issues

Hi Everyone,

As mentioned in the title, I've got 5kva Synsynk Inverter connected to a BSL 51.2v LI Battery.

The person installed the system for me is AWOL and I'm unable to get him to come and fix an issue I'm experiencing.
 
Basically my Battery shuts downs at the percentage it's meant to reset (35%) and doesn't come back on until I have power again, and then when the power does come back, it takes about an hour to start charging, and according to the LED's on the battery and the Sunsynk app it starts charging from 0%. The battery also takes very long to startup after I manually shutdown the inverter and battery of I need to save the battery power for later.

Yesterday we had a power outage after load-shedding that lasted about 20 hours, as I work from home, I manually switched off the inverter at battery, to save power so I could work today in case the power wasn't restores, when I switched of the battery it was at 47%, I switched everything back on again at 1am when the power came back, but the battery took over before it started showing any sign of power, but when it did start the level was still at 47%.

Can anybody running the same system possibly send me their settings so I can compare to see if the setting I have are correct, or someone that has expertise advise me on what I can do.

I currently don't have any solar panels connected to my inverter if that makes any difference.
 
I've attached pics of my battery for reference as well as my battery settings, please let me know if there's any other info than will help identify the issue.

Your Float, Absorption, and Equalization Voltages seem a bit high.

Try:- Float = 54.8V, Absorption = 55V, and Equalization = 54.9V

I see the Recommended Charge Current = 50A, Recommended Charge Voltage = 55V, Max Charge Current = 80A, Max Continuous Discharge Current = 90A.

Always good to be kind to your batteries if possible. :)
