Depth of Discharge for my PV system’s BYD 7.7kW LFP battery

What is a reasonable Depth of Discharge % for my PV system’s BYD 7.7kW LFP battery,so to maximize its longevity? Should I keep SoC between 20%-80% e.g. 60% DoD?The inverter default battery SoC limit configuration is 5%-100%, but 95% DoD feels like it would be bad for the battery
