Precept 36A - DC fuse for Xantrex freedom 1200 inverter?

[Barnesmobile]

Hi all,

We have a 2019 Jayco Precept 36A. The problem were experiencing is the Xantrex Freedom X 1200 inverter is not switching to battery mode. It works fine when generator power is detected.

I figure either:
a) the inverter is broken in this way and the inverter needs to be replaced OR
b) the dc fuse blew from the battery to the inverter (screenshot attached)

Does anyone know where this DC fuse might be? I can't find one.

The strange part is that the inverter can see the battery (viewing panel shows the current battery state of charge) so I'm doubting that it's b) either.

Any other ideas would be appreciated.

Thanks in advance! Happy traveling!
