9-Layer 19" Rack for Deye BOS-G Battery Systems
The Deye 3U-LRACK is a tall, 19-inch metal rack made to hold Deye’s BOS-G high-voltage batteries. It can fit 8 BOS-G 5.12 kWh battery modules plus 1 high-voltage control box in one neat cabinet, for a clean, safe indoor battery setup.
BSC Renewables uses this rack when building larger, rack-style battery systems for homes, farms and businesses.
What the 3U-LRACK Actually Is
It’s a standard 19″ battery rack made for Deye’s 3U battery modules. It can hold:
- 8 × BOS-GM5.1 5.12 kWh batteries, and
- 1 × high-voltage battery cluster control box (HVB750V/100A).
It’s designed for indoor use, in a plant room, garage or battery room. Think of it as the “battery cupboard” for your Deye BOS-G system – everything in one place, not scattered around the room.
Why Use a Proper Deye Battery Rack?
1. Keeps Everything Neat and Organised
Because the rack is designed by Deye for Deye batteries:
- Each battery and the HV box slides into its own slot.
- Cables can be run short and tidy inside the rack.
For you, that means:
- The battery bank looks clean and professional, not like a stack of boxes on shelves.
- It’s easier to see what’s what if anything ever needs checking or replacing.
2. Built for BOS-G High-Voltage Systems
In Deye’s small-scale C&I (commercial and industrial) storage docs, the 3U-LRACK is shown as part of the BOS-G high-voltage system: up to 3–12 BOS-GM5.1 modules in series per rack.
So it’s ideal if you:
- Want more storage than a single wall battery, or
- Are running a larger home, farm or small business with higher energy needs.
The rack helps BSC Renewables build your BOS-G system in a way that’s easy to expand later if you need more storage.
3. Compact Footprint, Big Capacity
Deye lists the rack size as: 530 × 602 × 1629 mm (W × D × H) and about 41 kg empty.
So you get:
- A tall, narrow cabinet that fits nicely in a corner or along a wall.
- Room for up to 8 batteries plus the HV box in that one footprint.
It’s a simple way to keep plenty of storage in a small floor area.
4. Optional Front Door
The LRACK can be supplied with an optional door.
This lets you choose:
- Open front – easier access and visibility, or
- Door fitted – a cleaner look and an extra layer of physical protection.
BSC Renewables can recommend which option is better for your site.
