Hi, I am adding the Growatt 3000TL LVM-24P in a van conversion but I found it is difficult to add 12v for the applications in the van. Could anyone get me a guide to wire? Thanks!
Well for starters you will need a 24 to 12 volt buck converter.
Do you have a system diagram to share with us so that we may better understand your setup?
Looks good, should be a fuse between the inverter/charger and the busbar.
Also a fuse between the buck converter and the busbar.
And a fuse block with fuses between the buck converter and the loads.
