Use inverters + capacitor bank. If we choose to have both inverters and capacitor banks, in ¨Define strategy settings¨, we''ll see that we can slide two ends of a violet line on the bar to choose the portion of the system that will be compensated by the capacitor banks, and the left end of it is to determine exactly up to which point to use inverters only (yellow line).
The DC link capacitor is placed between the DC (in this case, the battery) and the AC (which is the load side) of the voltage inverter. The capacitor is placed parallel to the battery, which maintains a solid voltage across the inverter. The device helps protect the inverter network from momentary voltage spikes, surges and EMI.
Design factors that affect the choice of an inverter DC-Link capacitor.
