    2.4.1 DC to AC Invert Overload Capacity The MS6048D inverter/charger has different overload capacities, making it ideal to handle demanding loads. 1 For 110%<Load<150%, Fault (Power off) after 10 seconds. 2 For 150%<Load≤200%, Fault (Power off) after the 5 seconds.
  • Page 9 www.sigineer.com Software timer will measure the time from charger start until the battery charger reaches 0.3V below the boost voltage, then take this time as T0 and T0× 10 = T1. Absorb Charging: This is the second charging stage and begins after the absorb voltage has been reached. Absorb Charging provides the batteries with a constant voltage and reduces the DC charging current in order to maintain the absorb voltage setting.
  • Page 10 AC Charging Current MPPT Solar Charger Max Charging Current MS6048D The MPPT Solar Charger will automatically work when the inverter is powered off. Even when the power switch is in unit off position, the built-in solar charger will automatically work when PV input voltage and battery voltage is qualified, this is to optimize solar production for battery charging.

  • Page 11: Dc&Ac Transfer

    www.sigineer.com 2.4.3 DC&AC Transfer While in the Standby Mode, the AC input of the inverter is continually monitored. Whenever AC power falls out of the trip voltages, the inverter automatically transfers back to the Invert Mode with minimum interruption to your appliances. The transfer from AC mode to Inverter mode occurs in approximately 10 milliseconds, with the worst case of 20 milliseconds.
