Inverter Fan Operation

The inverter contains two internal cooling fans that are automatically controlled. The speed of these
fans is determined either by 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 degrees Celsius (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 when none of the above conditions are met, or if the battery voltage is below
19.0V (24-volt systems)/38.0V (48-volt systems).
Whenever the inverter is fi rst connected to the battery, the fans will come on for about one second.
Info: The inverter's fans will not come on based on temperature sensed by the optional
Battery Temperature Sensor (BTS).

Using a Remote with the MS-PAE Series Inverter

The MS-PAE Series inverter has many advanced features. When the inverter is connected to a
remote, it allows these advanced features to be set up or enabled. However, the remote may
have a later/newer software revision than the inverter, so some of the features and functionality
in the remote may not be available with your inverter.
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, go to the TECH menus on your remote and
access the Revisions display.
2. Use the table below to determine the inverter's compatibility level (L1, L2, L3 or L4) 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:
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 you want. If your inverter does not have the required compatibility level for
a feature/setting you want, contact Sensata about a software upgrade.
