Modular Energy Storage Mounting for Ground Settling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Energy storage systems face issues due to ground settling, which can cause damage to walls and premature failure of system components, as they are not designed to accommodate movement.
Innovation Solution
A modular installation method that supports the inverter on the wall while allowing the batteries to be ground-supported, enabling them to move with ground settling, while keeping the electrical conductions stationary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the energy storage system is rigidly installed to the wall, then the system structure is stable and secure, but the wall and system components may be damaged due to ground settling movement
Solution Approach 1:
The energy storage system is divided into separate modular components (inverter, battery racks, conduits) that can move independently. The battery racks are separated from the wall mounting structure, allowing them to settle with the ground while the inverter remains fixed to the wall, resolving the contradiction between structural stability and accommodation of ground movement.
Solution Approach 2:
The mounting system transitions from a rigid fixed installation to a dynamic configuration where battery racks can vertically translate along the wall-mounted rails. This dynamic capability allows the system to adapt to ground settling while maintaining secure wall attachment, preventing damage to both the wall and system components.
2Reliability
If the battery racks are fixed to the wall, then the system is secure and stable, but the electrical conduits are moved and damaged due to ground settling
Solution Approach 1:
The system separates the battery rack mounting from the conduit routing. Conduits are routed independently through the wall and ceiling structure, while battery racks are mounted on movable rails. This segmentation allows conduits to remain stationary relative to the building structure while battery racks settle with the ground, extending conduit lifespan.
Solution Approach 2:
Wall-mounted rails serve as an intermediary between the fixed wall structure and the settling battery racks. The rails provide a guided path for vertical movement, allowing battery racks to settle without dragging or stressing the electrical conduits, thus protecting conduit integrity and extending their service life.
3Ease of manufacture
If the energy storage system is installed as a single rigid unit, then the installation is simple, but the system cannot accommodate ground settling movement
Solution Approach 1:
The system uses modular battery racks that can be independently mounted on wall rails, simplifying installation while enabling differential movement. Each rack is a self-contained module that can be installed and adjusted independently, maintaining ease of installation while providing adaptability to ground settling through the movable rail system.

AI summary
In various embodiments, an energy storage mounting system includes an inverter wall bracket mounted to a wall, wherein an inverter is coupled to the inverter wall bracket. The system includes a battery wall bracket to which a battery block is coupled. The battery wall bracket interfaces with an auxiliary bracket that is mounted to the wall, is vertically translatable relative to the auxiliary bracket, and is at least in part ground-supported.
