Does anyone know what size in 'U' units I'll need for 4 off Pylontech 5000s? I think they'll fit in a 16U, but before I buy a rack too small, am I forgetting anything like cooling space between units, or space for shelf brackets? Thanks in advance.

Rack Size For 4 Off Pylontech 5000 Packs?
@Jonny B Did you install a rack?
I'm installing and just have the batteries stacked on a piece of wood with small pieces between each battery for now. My solar guy says this is fine and there is no real benefit to a rack in my case, but I'm interested to hear what others think?
Dear Jonny-b, 4 Pylontech US5000 will fit into a 16U rack (see pdf), I believe that the space between units (16,8mm) is a little lower compared with the 4 units rack mount you see in the Pylontech manual, so it will be Ok depending of how do you use the batteries, environment temperature, etc.
According to the manual each unit must be placed on a shelf (for a min. wieght of 40kg). These kind of shelves need some support on the rear side, not only the front. It is not allowed to mount the Pylontech unit only with the front "ears" only, these are just for securing in position to the rack.
Also be aware of a proper air flow, a glass door looks nice but the airflow is blocked.
Yes. Interestingly the Pylontech cabinets simply have supporting rails at both of the sides, not a full shelf.
Has anyone tried this setup?
Is the airflow between US5000 batteries enough in a U16 rack?

@jonf3n Not that hot warm but not hot, mine are in a celetex box with a 60watt heat lamp and will be a toasty 27 to 30 degrees at 70amps charge for 4 or 5 hours
I’ve had three US5000 modules in a 16U Samson SRK16 rack for almost 5 months with no issues. I’ve spaced the batteries to leave space for a fourth module but currently have networking gear in the top slots. I’ve run the system at max charging of 70A from inverter, 120A from MPPTs and max discharge of just over 100A on several occasions and the batteries never seem to rise much above ambient temps.
My rack is open front and back, and has rear supports for the batteries. Let me know if you want any more info.

pylontech advises to keep space between them so i would advice to use a 20U rack
i have 3 pylontech 5000 in a 16u rack and they have never been hot, just warm
most important is the shelving, the rack mount on the front of the 5000s can not hold there own weight!!
Completely agree @duivert !
