7.1. Introduction to inverter systems
AninvertersystemtakesbothACand48Vdcinputandconvertsitto120Vacoutputvoltage.The
invertersystemcanoperateinoneofseveralmodes:
•
Line (AC-AC): WhenACinputispresenttheinvertersnormallytakethisvoltageandconvertitto
ACattheoutput.
•
Inverter (DC-AC): WhenACinputislost,theinverterstaketheDCinputvoltageandconvertitto
ACattheoutput.
•
Bypass Mode: Whenthemaintenancebypassswitchhasbeenusedtobypasstheinvertersand
directlyconnecttheACinputtotheoutput.
