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 80°C
degrees Celsius (176°F), 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
60°C (140°F), 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
9.5V (12-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.

3.10 Using a Remote with the ME Series Inverter

The ME Series inverter—when connected to a remote control display (i.e., ME-RC, ME-ARC)—has
many advanced features. The inverter and remote communicate with each other to allow 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 (and Table 3-3) 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 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 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 you want. If your inverter does not have the required compatibility level
for a feature/setting you want, contact Sensata Technologies to determine if there is a software
upgrade option for your inverter.
