Epever Hybrid Inverter & 48V 5KW SOK Lithium battery compatibility

We have just purchased 3 100ah SOK batteries after watching a lot Will's you tube videos( we live in New Zealand). We went with a company who had good reviews and who stocked these batteries as couldn't find reviews on others offered and felt these were the right fit for us. The supplier we brought the batteries from was sure they would be compatible with our current inverter (Epever UP5000-M10342), we have tried to change the setting to what they suggested but the inverter will not get to the settings (its impossible), our solar is working but my worry is can any damage be done to either the batteries or the inverter, we're thing about $10,000 worth of batteries, so a wee bit worried could this cause a fire.
They said to do the setting in order as it would change the settings in order , but we aren't able to do that.
Here is the sequence and settings we were told to set it too and the one settings we can get to on our inverter
1,BTP- battery type - USER(can do this on inverter)
2,BCT- battery boost charging time-120 (set it to this)
3,BCV-Boost charging voltage-57.6 (we could only set it to 55.2)
4,FCV-Float charge voltage-55.8 (could only set it to 54.8)
5,OVR-Over Voltage reconnect-57 (would only go as low as 58.4)
6,OVD-Over Voltage disconnect-58.8 (would only go as low as 62)
7, LVD-Low Voltage Disconnect-51.2 (would only go as high 45.2)
8, LVR-Low Voltage Reconnect-52 (was able to set to this).
Please any advice would be much appreciated.
The inverter market isnt as big in NZ if we need to get a new one.
There are the DEYE inverter,6kW hybrid single phase $2500, the MPP 6kW 49 Hybrid inverter (not much info on this one but at the moment it is $1300)
there is also an ELV 5kW hybrid invert for $1399 or an LV 5kW hybrid inverter
 
Assuming you have 48v lifepo4 battery, not ideal, but will work.

Check the voltage when charging. You may not need "boost charge time". Once the battery hits the charge voltage, lifepo4 should be ok. Make sure max charge voltage doesn't exceed 57.6v.

High voltage disconnect is high, but shouldn't get there.
Charge voltage of 55.2 and 54.8 are good enough.
Low voltage disconnect of 45.2 is ok too (above 40.0v hard minimum).
