Racky Rax Additonal Shelf
RackyRax PowerCube battery rack — Built around the PowerCube H2 — and the BMU needs a shelf of its own.
A PowerCube string is a lot of weight in a small footprint, and it has to be supported at every module rather than stacked on itself. That is what these racks are for: a shelf per battery, in a frame designed around the PowerCube H2 rather than adapted from a network cabinet.
About the RackyRax PowerCube battery rack
Racky Rax build them to hold a full string, so the rack is chosen by the string length: eight batteries or twelve.
The detail that catches people out is the shelf count. A rack holds its string, but the BMU needs a shelf of its own, so a full rack plus BMU needs one additional shelf on top of the rack as listed. The -PACK versions have that shelf in the box already.
What does this fit?
This is the rack a Pylontech PowerCube H2 string is built in.
Designed around the Pylontech PowerCube H2 module (PYL-PC-H2-BATT). Choose the rack by string length, and remember the BMU needs a shelf of its own: a full rack plus BMU needs an additional shelf.

What the job needs
The details that decide whether this suits the system:
- Built for the Pylontech PowerCube H2, part PYL-PC-H2-BATT.
- RR-PC-13 holds a full string of twelve batteries; RR-PC-9 holds up to eight.
- An additional shelf (RR-PC-SHELF) is required for a full rack plus the BMU. It is not in the bare rack.
- The -PACK versions of both racks include that additional shelf.
- The PowerCube BMS on these systems is PYL-PC-SC1000-100-BMS.
- Check the floor loading. A full twelve-module PowerCube string in a rack is a substantial point load.
Where this earns its place
The rack is chosen by the length of the string.
