I have a 2024 22BHE which has blown the 30A fuse leading to the battery bank numerous times. I wanted to share my experience in case anyone else is experiencing the same issue.
We've been using our trailer since we purchased it in November, 2023. Right away, I installed 3x 100ah LI batteries (and relocated to a massive unused space under the sink). Since doing so, I've blown countless 30a fuses (as well as 60a, but more on that later). The power converter installed is a WFCO WF-9855-AD, and there is a WFCO promotional sticker which claims it can detect the difference between lead acid and lithium batteries.
The WF-9855-AD is rated to charge at 14.6VDC @ 50A for a Lithium battery. My bank of 3 batteries is capable of soaking up 150A, so the 30A fuse between the converter and the battery bank is blowing anytime I try to charge up from even 10-15% depleted. When camping this is resulting in not being able to charge from the generator and a pretty uncomfortable night after quiet hours. I’ve even bypassed the fuse using jumper cables in order to get a charge.
It doesn't seem like too much to ask that the stock wiring be able to handle the load placed on it by the stock power converter.
I attempted to correct this by upgrading the wiring to the battery bank with 6g copper and a 60A fuse (based on the spec sticker on the WF-9855-AD stating it's max output was 55A. However, my first field test of this configuration immediately blew a fuse.
It wasn't until I purchased a loop multimeter to test the actual amperage that I learned that the converter spikes its output to ~68A immediately upon activation, blowing my 60A fuse. I'm in for another wiring upgrade to get this all working but I’m very close to closing this issue up.
Has anyone else run into this issue? It doesn’t seem like the kind of problem that would be limited to this model.
