Introduction
1.0 Introduction
Congratulations on your purchase of a MSH3012RV inverter/charger from Sensata Technologies.
The MSH3012RV is designed especially for RV applications; it is a “hybrid” pure sine wave inverter
and includes a RV-C connector to allow RV OEM’s an easy way to multiplex with this inverter.
Why is the MSH3012RV a “Hybrid”?
Most inverters only use one source of energy to power
the inverter loads—either from the incoming AC power (i.e., shorepower or generator) or from
the batteries. The MSH3012RV combines the energy from both the AC input and the batteries to
power the inverter loads. This feature gives the inverter the ability to recharge the battery when
there is surplus power, or to deliver more power to the loads if they require more than the AC
input can supply by itself.
Info:
This is a sizable manual and much of it is fairly technical. Terms may be used
throughout the manual that are unfamiliar to you. Refer to the Inverter/Charger
Terminology glossary in Appendix D for clari
fi
cation.
The MSH3012RV inverter/charger includes the following:
• A 3000w/12v model in a small installation footprint
• Pure sine wave output
• Automatic PFC (Power Factor Corrected) multi-stage battery charging
• RS485 standard communication protocol
• Inverter-mounted ON/OFF switch with LED indicator
• Each input has 50-amp AC capability with intelligent AC input transfer
• Field serviceable for quali
fi
ed personnel—tested repair kits available
• Automatic battery temperature compensation (when using the Battery Temperature
Sensor) for optimum charging even during extreme temperature changes
• Overcurrent, over-temperature, and high/low battery voltage protection
• RV-C connector and protocol to communicate on a RV-C network bus/backbone
• Non-volatile memory for settings
The following accessories are also available for use with the MSH3012RV inverter/charger:
• ME-AGS-N
(Automatic Generator Start Module – Network version) – automatically starts/
stops your generator.
• ME-ARC50
(Advanced Remote Control) – easy to read LCD display panel that allows advanced
inverter set up, control, and troubleshooting.
• ME-BMK
(Battery Monitor Kit w/ Shunt) – provides precise DC voltage/current measurements
and information on your battery’s State of Charge (SOC) condition.
• ME-RC50
(Standard Remote Control) – easy to read LCD display panel that allows standard
inverter set up, control, and troubleshooting.
Regulatory Compliance
The MSH3012RV inverter/charger is designated as a Standalone power inverter with an internal
battery charger. It can be connected to a utility grid (i.e., shorepower) or to a generator to
allow the inverter batteries to be charged, and to power inverter loads while connected. The
MSH3012RV is not a grid-interactive (also known as utility-interactive) inverter and does not
have the capability to export (or sell) power back into the utility grid.
The MSH3012RV is intended for RV use. It has been tested and listed to UL 458, 5th Edition
(Power Converters/Inverters and Power Converter/Inverter Systems for Land Vehicles and Marine
Crafts) for use in the US; and is also certi
fi
ed to CSA C22.2 No. 107.1-01 (General Use Power
Supplies) for use in Canada. It has been tested and certi
fi
ed to these product safety standards
by Intertek Testing Services (known as ETL), which is a Nationally Recognized Testing Laboratory
(NRTL). Organizations that are designated as a NRTL are quali
fi
ed to meet Occupational Safety
and Health Administration (OSHA) regulations to perform independent safety testing and product
certi
fi
cation.
