The MMSA1012 inverter/charger is equipped with the following:
• Continuous 1000-watt output power and 50-amp charging (at
45°C, or 113°F)
• Numerous protection features to provide peace-of-mind
operation and safe operation
• AC transfer switch circuitry; allowing incoming AC power to
continue to pass thru to power loads even if the inverter is off
• Dead battery charging for batteries that are extremely low
• Automatic 4-stage battery charger with power factor correction
and temperature compensation—for optimum battery charging
(using the temperature sensor)
• DC terminals with Anderson connectors for quick DC connection
• True RMS output voltage regulation to ensure the inverter
will deliver the correct amount of power—within the DC input
voltage range and the continuous output power level
• Quick connection accessory and remote ports—easily accepts
several optional remote controls and the Battery Temp Sensor
1.5.1 External MMSA1012 Features
This section covers the many features available on the MMSA1012
inverter.
1
Power ON/OFF Switch & LED Status Indicators
–
a momentary pushbutton switch that alternately turns
the inverter on or off, and
fi
ve LED status indicators
(INV, BULK, ABSORB, FLOAT, and FAULT) for monitoring
inverter and charger operation.
2
Auxiliary Output Circuit Breaker
(AUX OUT)
– a 20-
amp circuit breaker that provides overload protection for
the aux DC output.
3
Input Circuit Breaker
(AC IN)
– a 20-amp circuit breaker
to protect the unit’s internal wiring and pass-thru relay.
4
Output Circuit Breaker
(AC OUT)
– a 15-amp circuit
breaker to provide another layer of overload protection.
This is not a branch circuit-rated breaker. Separate output
breakers may be required on the output.
5
GFCI Outlet
– a Ground Fault Circuit Interrupter outlet
(with test and reset capability).
6
Mounting Flanges (x4)
– two
fl
anges on each side to
secure the inverter to a shelf/wall.
