1.2 How an Inverter/Charger Works
An inverter takes direct current (DC) from your batteries and turns it
into alternating current (AC), like you use at home. The MMSA1012
inverter/charger also takes alternating current and transforms it
into direct current to recharge your batteries.
There are three modes of operation associated with this inverter:
• Inverter
Mode
: DC from the batteries is transformed into AC
for powering your vehicle.
• Standby
Mode
: The unit operates as a battery charger to
convert incoming AC power into DC power to recharge the
batteries while continuing to pass the incoming AC power
directly to the inverter’s output—to power any AC loads.
