Checking Firmware & Reading Inverter Error Codes

If you are having an inverter issue (beeping or other problem), we may need you to check the firmware version and/or read the inverter error code. This information is available using the inverter remote (pictured below) that was given to you when your system was initially installed.

  1. You will need to connect the RJ12 cord to this remote – instructions here.
  2. Once the remote is plugged in, turn the inverter on using the switch on the control panel on the wall. When the inverter is on, the remote should turn on. It will display Rx.x then rx.x (where X is a variable number and these are the levels of firmware). After that, it will go to the main default display. 
  3. When the error is occurring, the inverter remote will display an error code: E followed by a number. 

Common error codes:

  • E13 is a GFCI error code. If it is constantly beeping and a constant E13 any time the inverter is on, check the GFCI outlet on the inverter and make sure it has not been tripped. 

    1st Generation Revels: The inverter is accessible behind this panel on the front of the bench seat:

    2nd Generation Revels: The inverter is underneath the step in front of the bench seat. Remove the Phillips screws on top of the step then lift off the top to access the inverter. The GFCI is on the short side of the inverter::

  • If the E13 error code it is not constant and ONLY shows when the AC or other high load item cycles on shore power, please update your firmware as this is a known issue that Kisae addressed with a firmware update.
