Racky Rax Cabinet 12U 550D - Black
RackyRax 19-inch battery cabinet — Welded steel, lockable glass front, assembled — sized in rack units, not in batteries.
A rack-mount battery needs a rack, and on a domestic or light commercial job that usually means a cabinet rather than an open frame — it keeps the terminals behind a locked door and the installation looking finished.
About the RackyRax 19-inch battery cabinet
These are 550 mm deep 19-inch cabinets in welded steel, with adjustable front and rear mounting profiles, ventilation slots in the top, removable sides and a lockable glass front door. They arrive assembled.
Size them by the modules, not by the kWh. The same 12U cabinet takes five Pylontech US2000B Plus, three US3000 or three Fox ESS HV2600, because those modules are different heights.
One fixing rule applies throughout: batteries are attached using the front mounting holes only.
What does this fit?
This is the 19-inch cabinet a rack-mount battery string lives in.
These are 19-inch cabinets sized by rack units. The battery count depends on how tall the module is: a 12U cabinet takes five US2000B Plus, or three US3000, or three Fox HV2600. Batteries must be fixed using the front mounting holes only.
