Unfortunately I have limited vertical height under the bed of my van (just over 600mm). With the batteries mounted below, this only gives me about 375mm of vertical height to work with, however width won't really be an issue.
Note I am missing some components. The red rectangle is a 60A fuse between the MPPT and positive bus bar. The measuring tape is the mSeries 6006 switch for the positive terminal on my parallel batteries. The coaster is the DC isolator switch for the solar panels.
I have the Orion Tr awkwardly mounted on its own as I've read this is prone to overheating and ideally needs 100mm clearance for optimal temperatures. Potentially I'll also add active cooling, but unsure. #lifestyle source
