Scalable rack-mounted battery storage from 16kWh to 1MWh. Designed, specified and installed by Energy2 engineers — with cell-level telemetry and UK sovereign data infrastructure.
3–5 year typical payback · UK engineering & support · 0% VAT applied
Each rack module delivers 16kWh of useable storage. Link multiple racks to reach 1MWh of capacity — all managed from a single platform.
16kWh — 150A / 7.68kW
48kWh — 450A / 23.04kW
96kWh — 900A / 46.08kW
1MWh+ — Scalable output
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, specification, 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.
Tariff arbitrage, peak shaving and demand response. Savings from day one with full payback in 3-5 years.
Worked example for a 96kWh system at a mid-sized commercial premises on a time-of-use tariff with peak demand charges.
Based on a 96kWh / 6-module system. Actual savings depend on tariff structure, usage patterns and grid services participation. We provide a detailed ROI projection as part of every site survey.
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 |

Most commercial systems are fully installed within 48 hours. We handle the complete process — from site survey through commissioning — with our own engineering team. No subcontractors.
In most cases, indoor battery installations do not require planning permission. Our systems are IP21-rated for indoor use and fit within standard server rack dimensions. We advise on any specific requirements during the free site survey.
Our commercial rack modules are CE, UN38.3, and IEC 62619 certified. Energy2 is an MCS-certified installer, RECC member, and TrustMark registered. All systems comply with current UK fire safety and electrical regulations.
Yes. Energy2 commercial systems are compatible with all major solar inverters including Victron, Sunsynk, Growatt, and Solis. We design the integration as part of the system specification.
All operational data — including cell-level telemetry — is encrypted and hosted in secure UK data centres. We do not route data through overseas manufacturer cloud platforms. Full UK data sovereignty.
Energy2 systems are designed as serviceable infrastructure. If a cell or module develops a fault, it can be isolated and replaced individually — you don't need to replace the entire unit. Cell-level telemetry means we often detect issues before they become failures.
Most commercial installations achieve full payback within 3-5 years through tariff arbitrage, peak shaving, and demand response. A 96kWh system typically saves between £12,000 and £25,000 per year depending on usage patterns and tariff structure. We provide a detailed ROI projection with every site survey.
