Deye 3U-HRACK Battery Rack

1. Everything in One Tidy Stack

Because Deye designed the rack for its own BOS-G system:

• The BOS-G 5.12 kWh modules and the high-voltage control box slide into the rack like equipment in a server cabinet.
  
  
• Up to 12 batteries and 1 HV box fit in the one frame.
  
  

For you, that means:

• The battery bank looks neat and professional, not like a pile of boxes on the floor.
  
  
• Cables are shorter and better organised, which helps with safety and servicing.
  
  

2. Made for Bigger BOS-G Systems

On Deye’s BOS-G product page, they show BOS-G systems using 3–12 battery modules in series (15.36 to 61.44 kWh per rack). 

The 3U-HRACK is the rack that holds a full 12-module BOS-G system plus the HV control box, so it’s ideal for:

• Larger homes with high demand
  
  
• Farms and rural properties
  
  
• Small commercial sites (shops, workshops, sheds, offices)
  
  

If you know you need more than a small wall battery, this is the rack Deye expects you to use.

3. Big Capacity in a Small Floor Area

From Deye’s own figures: 530 × 602 mm footprint and about 2.2 m tall. 

So you get:

• A narrow cabinet that can sit against a wall in a plant room or garage
  
  
• Room for up to 61.44 kWh of BOS-G batteries in that one rack, when fully populated
  
  

That’s a lot of storage in a very compact space.

4. Official Deye Hardware, Not a Generic Rack

The 3U-HRACK (SKU: 10100401000078) can be installed with an optional door.

So you know:

• The rack is part of the official Deye BOS-G system, not a third-party add-on.
  
  
• You can choose it with or without a front door, depending on how you want it to look and how much physical protection you’d like.
  
  

That helps with compliance, warranty and long-term support.
