Operation
3.12 Inverter Fan Operation
The inverter contains two internal cooling fans that are automatically controlled. The speed of
these fans is determined either by the internal temperature of the inverter or by the load on the
inverter. The inverter’s fans will come on under the conditions listed below:
• Fans run full speed if the internal transistors (FETS) or the power transformer reaches 176°F
(80°C), or the inverter is running at 100% of its rated load.
• Fans run medium speed if the internal transistors (FETS) or the power transformer reaches
140°F (60°C), or the inverter is running at 50% of its rated load.
• Fans run low speed when the inverter is running at 25% of its rated load.
The fans shut down if none of the above conditions are met, or if the battery voltage is < 9.5V.
Whenever the inverter is
fi
rst connected to the battery, the fans start for about one second.
Info:
The inverter’s fans will not come on based on temperature sensed by the optional
Battery Temperature Sensor.
3.13 Using a Remote with the MSH3012RV Inverter
The MSH3012RV inverter when connected to a ME-RC or ME-ARC remote has additional features. The
inverter and remote communicate with each other to allow these features to be set up or enabled.
However, if the remote has a software revision that was developed after the inverter’s software,
some of the newest features and functionality in the remote may not work with your inverter.
Info:
If using a remote control (i.e., ME-RC or ME-ARC), plug the remote cable into the
Network (green label) port on the MSH3012RV inverter/charger.
Note:
If using a remote control, you can NOT use the RV-C connector port to communicate with
the inverter. The MSH3012RV inverter will only communicate with the remote control if connected.
Use the steps below to determine what remote menus/features are available with your inverter:
1. Obtain your inverter’s software revision.
Note: To view the inverter’s software revision level, push the TECH button on your remote and
access the Revisions menu.
2. Use the chart below to determine the inverter’s compatibility level (L1, L2, L3, L4 or L5) based
on your inverter’s software revision.

3. After determining the inverter’s compatibility level, refer to the remote’s compatibility matrix
(
fi
nd it online at: www.SensataPower.com) to determine which remote features/settings you
can use based on your inverter’s compatibility level.
Note: If your inverter’s compatibility level is the same or greater than the ‘Inverter Model/Level
Required’ on the remote compatibility matrix on our website, then your inverter can support the
device setting/feature. If your inverter does not have the required compatibility level for a feature/
setting you want, contact Sensata Technologies to see if there are any software upgrade options.
