So I am still in the prep stage for installing the Victron upgrade with the XS50 B2B and the Multiplus 1600va Inverter/Charger.
All the bits are mounted onto a fireproof board to be slid into place , so it's just the final cable connections now ( and the snipping of the R37 ).
I am sure I will get shot down now but please help. In the photo attached of my existing CBE522 charger, I have highlighted "B+/B-" and "D+?" wires/cables.
[1] If/when I snip the R37 what do I do with these cables ?
[2] If I remove the old charger where do I then bolt down those B+/B- cables too ?
[3] Do I just leave the white cable loose ( tie-wrapped somewhere ) or disconnect it from the CBE distribution board ?
[4] On an earlier thread ( back in 2020 ) when using a lower amp B2B posters identified the middle 50A fuse as being for the original B2B feed though I did not have a B2B. I have installed a 100a mega fuse in the spare slot which will attach to the 25mm cable run through the double floor to the "B2B in" in the garage ( via a 2nd 100a midi fuse ) then out ( via a 3rd 100a fuse to the positive busbar connection. Do I just leave the original fuses in place ?
[5] Is it good practice to have the glass "up" on the engine bay fuse or face down ?
[6] a VanBitz battery charger is connected to the B2B ( purchased from Roger Ivy at Offgrid and followed his video on how to do that ! Thank you Roger Ivy )
Earths : B2B 25mm cable fixed to the 250A busbar which is fed to ground with a 50mm cable bolted to the chassis. The inverter/charger is fed to ground with a 6mm cable bolted to another part of the chassis ( it's 50mm cables sitting on their respective +/- busbars ).
The original earth points are still in place and bolted to another part of the chassis.
At present, none of the new kit is actually connected to the existing system.
[7] What else do I need to consider ?
Thanks in advance for guidance.
