The DropBox BESS Product Series Explained: G, E & S Series

Battery Energy Storage Systems (BESS) are not one-size-fits-all. That’s why DropBox Green Energy Solutions offers a family of BESS products tailored for different power, space, and application needs, including the G Series, E Series and S Series.

📦 DropBox G Series — Compact & Efficient

Designed for commercial environments where space is limited, the G Series provides efficient, modular energy storage with built-in UPS and MPPT for renewable integration. Its compact design makes it ideal for installers who need flexibility without sacrificing performance.

🚚 DropBox E Series — Scalable Powerhouse

The E Series steps up capacity and power, suited for larger commercial sites, industrial facilities or multi-use environments. With advanced thermal management and robust build quality, it’s engineered for high-demand applications and long-term reliability.

🏭 DropBox S Series — Heavy-Duty Performance

For projects requiring the highest capacity and rugged deployment, including off-grid installations, EV charging hubs and utility-scale storage, the S Series delivers. These containerised systems handle demanding energy profiles with efficiency and resilience.

Choose the Right BESS

Selecting the right BESS depends on load profile, space constraints, renewable integration plans, and energy goals. DropBox GES offers expert consultations to recommend the best system for both present and future needs.
