MM Series Models

MM612 – a 600-watt inverter with 7-amp AC transfer relay. The AC input and
output are provided with pigtail wires to allow hardwiring to an AC distribution
panel. Features neutral-to-ground switching for mobile applications.
MM1212 – a 1200-watt inverter/charger with 12-amp AC transfer relay and
70-amp, 4-stage PFC charger. The AC input and output are provided with pigtail
wires to allow hardwiring to a main AC distribution panel and an inverter sub-
panel. Features neutral-to-ground switching for mobile applications. Includes
a 15' battery temperature sensor.
MM1212-G – a 1200-watt inverter/charger with 12-amp AC transfer relay
and 70-amp, 4-stage PFC charger. AC input is provided by a standard 3 ft.
plug-in power cord, and the AC output is provided by a standard GFCI two-
plug outlet. Features neutral-to-ground switching for mobile applications.
Includes a 15' battery temperature sensor.

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. With MM Series models that
have the battery charger feature, it also takes alternating current (when
connected to a generator or to shorepower) 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 boat or RV accessories.
Standby Mode (MM1212/MM1212-G models): 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.
