I have the followings parameters values:

Inverter XW6048                            MPPT60
Grid Support - Enabled                  Bulk Volts - 58.1
Grid Support Volt - 64V                  Absorb Volts - 58.1
2 Stage Charging                           Float Volt - 54.0
Sell - Enabled                                 3 stage Charging
Bulk Volts - 58.1                             ReCharge Volt - 51.0
Absorb - 58.1
Float - 54.0
ReCharge Volt - 51.0

Please let me know if I have to change one of them.
Sometimes even we have a bright sun the MPPT60 shows they are producing 350Watts and almost selling 0 to the grid. If I turn off the 60 amps breaker of the MPPT60 and turn it on the production increase to over 3,500Watts and increase the watts sent to the grid. I have 16 360Watts PV's connected to 2 MPPT60.
Appreciate your comments

    Your Battery voltage likely needs to be larger than Grid Support Volt
    else how does your system get to the Grid Support Volt ?
