I have the amps set at 80 now,

Per inverter? 20 A per battery module (C/5) seems very cautious, especially for a maximum figure.


what should the back to discharge voltage be, i currently have it at 56V, and the back to grid voltage at 45V and what should the bulk and float charging wees. 

Despite the manufacturer recommending 54.0 ± 0.5 V, I'd go with the voltages that work best for Pylontechs (which are also 15S LFP).
