Scalable rack-mounted battery storage from 16kWh to 1MWh.1 Designed, manufactured and installed by Energy2 engineers — with cell-level telemetry and UK sovereign data infrastructure.
Each rack module delivers 16kWh of useable storage. Link multiple racks to reach 1MWh of capacity — all managed from a single platform.1
No one else can design the product, engineer the system, and fully install it — end to end, within 48 hours — all from the same company.
Design, manufacturing, system integration and installation — all one company. No middlemen, no fragmented supply chain.
Every cell monitored individually. Voltage, temperature and performance data — not just pack-level readings. Early detection of imbalance or thermal issues.
All operational data hosted in secure UK data centres. Not routed through overseas manufacturer cloud platforms.
Repairable infrastructure, not a sealed appliance. Faulty cells or modules can be isolated and replaced — not the whole unit.
Secure over-the-air firmware updates managed from the UK. Your system gets better over time — not fixed at manufacture.
A 96kWh system installed alongside existing solar PV at a secondary school, reducing peak demand charges and providing UPS backup for IT infrastructure. The system was fully installed during a half-term break with zero disruption to school operations.
We looked at three different battery providers. Energy2 were the only ones who could design the system, manufacture it, and install it themselves. That single point of accountability made the decision easy.
The cell-level monitoring is genuinely different from anything else we evaluated. We can see every cell, not just the pack. It gives us complete confidence in the long-term health of the system.
Energy2 systems keep operational data inside the UK, while many imported batteries rely on overseas cloud platforms for monitoring and updates.
| Energy2 | Typical Imported Systems | |
|---|---|---|
| Engineering model | Vertically integrated platform | Multi-vendor supply chain |
| Battery visibility | See every cell | See the battery as a single unit |
| Data & telemetry | UK-hosted cell-level telemetry | Overseas manufacturer cloud |
| Fault detection | Early detection of cell imbalance | Issues detected after pack-level deviation |
| Serviceability | Repairable — replace a component | Replace the whole unit |
| Lifecycle cost | Lower long-term maintenance | High replacement costs |
| Software updates | Continuous OTA improvements | Feature set fixed at manufacture |
| Accountability | Single engineering organisation | Multiple suppliers and installers |

Important information
Important Note: The energy performance and benefits of EESS is impossible to predict with certainty due to the numerous functions a system can be programmed to perform.
You should not sign a contract based on specific energy prices. Tariffs vary between suppliers and can change, so these costs can go up or down.
