The BigBattery ETHOS Rack Base Gives Each ETHOS Battery Stack a Stable, Level Foundation

The BigBattery ETHOS Rack Base is the metal foundation that an ETHOS battery stack sits on. The first ETHOS module locks onto the base, and the remaining modules and the ETHOS Control Box stack on top. The base keeps the stack level and aligned.

Every ETHOS stack needs its own rack base. One comes with each ETHOS Control Box and with each ETHOS expansion kit. Order this one when you are starting an additional stack from single modules, replacing a damaged base, or setting up a stack in a new location. Built by BigBattery for its ETHOS 48V home battery system, which is backed by a 12-year warranty and lifetime USA-based technical support.


BigBattery ETHOS Rack Base Features

Made for ETHOS Modules

The base matches the 26.5 in wide footprint of ETHOS modules so the stack locks into place securely.

Supports Multi-Stack Systems

ETHOS systems with four or more modules use two stacks side by side, each on its own base.

Included With ETHOS Hardware

A rack base ships with every ETHOS Control Box and expansion kit, so you only need this one for an extra stack or a replacement.


Real-World Applications

Second stack. Start a new stack beside an existing one when you add single modules.

Replacement. Replace a damaged or missing base.

Relocation. Set up a stack in a new location.

Yes. Each ETHOS stack sits on its own rack base.

Does the Control Box Include One?

Yes. The ETHOS Control Box and the ETHOS expansion kits each include a rack base.

Will It Fit Other Batteries?

It is designed for BigBattery ETHOS modules.
