  • Page 21: System Function Introduction

    4. System Function Introduction The SC series is a battery charger, a pure sine wave inverter and an AC transfer system in one compact enclosure. 1. The three-step charging function guarantees that the batteries are always charged 100% (User-selectable). 2. The pure sine wave inverter assures that the AC output voltage is perfectly reliable even when limited external AC power is available.
  • Page 22 4-1-1. Battery charging function description The SC series Series is equipped with a PFC (Power Factor Corrected) and PI (Proportional-Integral) multistage battery charger. The PFC feature controls the amount of power used to charge the batteries to obtain a power factor as close as possible to 1 (or unity). This causes the battery charger to look like a resistor to the line (forces the charge current wave shape to mirror the voltage wave shape).
  • Page 23 4-1-4. Float charging The third charging stage occurs at the end of the absorb charging time. While final charging, the charge voltage is reduced to the final charge voltage (determined by the Battery Type selection*). In this stage, the batteries are kept fully charged and ready if needed by the inverter. The Float Charging stage reduces battery gassing, minimizes watering requirements (for flooded batteries), and ensures the batteries are maintained at optimum capacity.

  • Page 24: Operation Mode Introduction

    4-2. Operation mode introduction The SC series is not just a combination of an inverter and a battery charger. There are many additional features which can be used to increase the total available AC power, even when external AC power is limited.
  • Page 25 ： Fig. 13 Power Sharing Function I The Power Sharing level can be set by means only remote control locally on the unit. When the total connected AC load reaches the level of the Power Sharing setting (20A), there will be no power left over to charge the battery.
  • Page 26 Later, when the AC load has dropped below the setting of the Power sharing function again, the battery charger of the unit will commence to recharge the batteries. ： Fig. 15 Generator Function 4-2-4. Power Support function With the adjustable AC input current limit function, Power Support function of the SC inverter will trigger OLP (over-load protection) when the output power is over loaded.
