How to Remove Firefly RV Control Panel: Complete DIY Guide (2024)

Our 2019 Fleetwood Discovery LXE has a malfunctioning Firefly multiplex control panel that needs to be completely removed. I've been putting this off for months because I keep hearing horror stories about people cracking their panels or damaging the surrounding woodwork during removal.

I need to access the back of the unit for some electrical work, but I'm honestly terrified of breaking something expensive. The panel seems to be mounted flush with no obvious screws or clips visible from the front. I've searched everywhere but can't find a complete walkthrough that covers the preparation, actual removal process, and how to get everything back together properly.

Can someone please provide a detailed DIY guide that covers all the steps? I'm willing to take my time and do this right - I just need to know the proper technique so I don't end up with a broken control panel or damaged wall. …more

How to Fix Firefly Battery and Victron System Conflicts in Your RV

Wondering if anyone else has dealt with a rental RV where the Firefly batteries and Victron system are constantly throwing conflicts I've never seen before. I have a 2020 Discovery LXE 40M that I've equipped with a complete Victron system - two Multiplus II inverters, Cerbo GX, and SOK lithium batteries. The problem is my coach's existing Firefly system is creating constant conflicts with the Victron equipment.

The AC units keep getting "shed" by Firefly, I'm getting random low voltage warnings even when my batteries are full, and my Auto Gen Start has completely stopped working. I've heard this might be related to waveform differences between the systems, but I'm not sure what that means or how to fix it.

I've seen some mentions of using dual transfer switches to isolate the systems, but I have no idea how that would work or if it would solve my Auto Gen Start issues. Has anyone actually resolved this Firefly-Victron nightmare? I really don't want to rip out thousands of dollars worth of equipment, but I need my RV systems to work properly! …more
