The DropBox BESS Product Series Explained: G, E & S Series
Battery Energy Storage Systems (BESS) are not a one-size-fits-all solution. Every site has different power demands, space constraints and operational priorities, which is why selecting the right system is critical. At DropBox Green Energy Solutions (GES), we offer a structured range of BESS products designed to meet these varied requirements: the G Series, E Series and S Series.
Each series is engineered to deliver reliable, scalable energy storage while supporting on-grid, off-grid and hybrid energy strategies.
DropBox G Series – Compact, Modular and Efficient
The G Series is designed for commercial environments where space is limited but performance cannot be compromised. These cabinet-based systems provide modular energy storage that can be scaled over time as energy demands increase.
With built-in UPS functionality and MPPT for renewable integration, the G Series is well suited to applications such as commercial buildings, retail sites, gyms and smaller EV charging installations. Its compact footprint makes installation straightforward, while intelligent energy management ensures efficient operation and cost control.
The G Series is an ideal entry point for businesses looking to improve energy resilience, manage peak demand or integrate on-site solar without major infrastructure changes.
DropBox E Series – Scalable Power for Commercial and Industrial Sites
The E Series offers a step up in both capacity and power output, making it suitable for larger commercial and industrial environments. Delivered in containerised formats, these systems are designed to support higher loads, longer discharge durations and more demanding duty cycles.
With advanced thermal management and robust construction, the E Series is engineered for long-term reliability in challenging operating conditions. It supports applications such as peak shaving, load levelling, renewable energy integration and backup power for mission-critical operations.
This series is particularly well-suited to manufacturing facilities, logistics centres, large retail sites, and multi-use developments.
DropBox S Series – Heavy-Duty Storage for Demanding Applications
For projects requiring maximum capacity and resilience, the S Series delivers heavy-duty, containerised battery storage designed for the most demanding energy profiles.
These systems are commonly deployed in off-grid installations, EV charging hubs, remote infrastructure and large-scale energy projects, where reliability and performance are non-negotiable. Advanced cooling, intelligent control systems and rugged design allow the S Series to operate efficiently under sustained high loads.
Choosing the Right DropBox BESS
Selecting the right BESS depends on several factors, including load profile, space availability, renewable integration plans and long-term energy goals. DropBox GES provides expert site assessments and technical consultation to ensure each system is matched precisely to both current needs and future growth.
Whether you need compact modular storage or large-scale industrial capacity, DropBox Green Energy Solutions offers a BESS platform designed to deliver reliability, flexibility and long-term value.
