Hi. I have a mercer 5kva inveter SOL-I-AX-5P which currently has 4 12v agm batteries connected to it. After 6 months of use the batteries no longer hold up so I bought the esener es-5.12kwh lithium battery. 

I would like to no what settings need to be changed on the inverter. Also I'm unsure of how to link the inveter to the battery via comms cable . 

Hi 

The recommend setting for the 5.12kwh batteries are: 

Bulk voltage 56.8v    
Float voltage 54.4V   
Cutoff voltage 45.6V

for the basic communication, there is a tutorial on youtube where they teach you at, if you still have a issue you can call esener on 010 449 9686, the guys from esener will assist you
