Operation

3.10 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

(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.

3.11 Using a Remote with the ME-G Series Inverter

The ME-G 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 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: Magnum-Dimensions.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 to determine if there is a software upgrade option for your inverter.
