Setting MT50 for max charging

[Jnj6370]

My system consist of 3-250 watt pv, 8-101AmpHr 12v batteries in parallel,40amp MPPT w/MT50 off grid system.need help on setting my MT50 for max charging, When I go into control parameters and choose flooded/batteries, it seems that my batteries stay in float mode during my peak charging time and don't get max charge for end of day. Can someone tell me what values I need to set all the parameters at??? Thanks, all info will be greatly appreciated.

Chances are that with 8 parallel strings of batteries there is a wiring issue which is causing your charging to go into float mode and not complete the full charge sequence.

Also with 750 watts you really need a 60Amp MPPT charger (750 watt / 12v = 62.5amps) so that 40Amp one is not big enough.
