Help - Loss of Power after installing MPPT/DC-DC Charger

Help

I swopped over my Epever Dual MPPT Charger today to a Renogy 50a MPPT/DC-DC Charger all connected up fine and showing as the solar and batteries all fine but when I went to use the drop-down bed the control panel turned it's self off

Checked all the connections and the panel resets but any power drain resets the panel immediately.

I then reinstalled the Epever unit and noticed it was really slow showing the volts on the display and again did the same thing so checked the inline fuse on the leisure battery and that had blown so will need to replace that asap.

Really weird and we are off next weekend so need to fix asap so open to any suggestions please ?

Looks like it was just a faulty fuse but I think I will pay someone to install the dc-dc properly.

Having melted the wiring loom on a maxi in 1978, and had had an ‘incident’ with house lighting wiring that I thought looked wrong and redid

I leave anything that needs tools and multimeters to someone better qualified

Which is pretty much anyone
