In today’s energy-driven world, industries and infrastructure projects need storage systems that are reliable, space-efficient, and cost-effective. Traditional containerized solutions work well in large deployments—but they often fail in locations where space is limited or scalability is critical.
That’s where Envault makes the difference.
What is Envault?
Envault is a plug-and-play, modular energy storage solution designed for industrial, commercial, and remote site applications. With its scalable architecture and compact footprint, Envault is redefining how energy storage systems are deployed.
- Modular Design: Each 18.2 kWh Envault module can be connected in parallel.
- Scalable Capacity: Multiple modules scale seamlessly to meet higher energy demands.
- High Energy Density: Delivers up to 218 kWh per square meter, one of the highest in the industry.
- Voltage Flexibility: Supports medium to high DC voltage (1000–1500 VDC).
- Compact Footprint: Provides 350–437 kWh in only 2 m², making it ideal where space is at a premium.

Skid Solution: Megawatt Storage in Container-Sized Space
For larger industrial applications, Envault offers a 12-unit skid solution:
- 5.2 MWh of storage capacity
- Fits within the footprint of a 40-ft container
- Simplifies deployment while maximizing space efficiency
This makes Envault the perfect fit for projects where big containerized systems cannot be placed, such as industrial parks, data centers, telecom towers, and remote infrastructure projects.
