What to do if Magnum Energy ME-ARC Remote Control is non-functional?
- VvjenkinsAug 6, 2025
If your Magnum Energy Remote Control shows no lights, no text on the LCD display, and doesn't respond to button presses, check the communication cable from the inverter to the remote. Ensure it is connected to the REMOTE port and that you're using the correct cable. A 4-conductor telephone cable can be substituted to test the cable. Also, make sure the inverter is connected to the batteries and operating correctly without AC power connected; it should be able to invert and power AC loads from batteries.
