From shopping street to production floor
the same supercapacitor core.
247 Energy serves both commercial and industrial environments from a single modular architecture. The use case determines the configuration — not a different product.
The 247 Energy supercapacitor system is engineered from the ground up for commercial environments — offices, hospitals, retail centres, hotels and logistics hubs where safety, aesthetics and operational continuity are non-negotiable. Unlike lithium battery systems, it installs inside any building without special fire suppression or structural reinforcement.
For ports, manufacturing plants, data infrastructure and heavy industry, 247 Energy delivers the high-power performance that lithium chemistry cannot match. Fast charge, fast discharge, cycle continuously — with an intelligent energy management layer that makes every kilowatt work harder.
Zero risk of thermal runaway. No flammable electrolytes. No toxic off-gassing. Compliant with indoor installation requirements without additional fire suppression systems.
Modular architecture scales from 15 kWh to multiple MWh. Configured to match your exact load profile, footprint and peak demand requirements.
Active cooling systems in lithium installations generate significant acoustic output. 247 Energy storage operates at 55 dB(A) — quiet enough for open-plan offices and patient areas.
Supercapacitors experience negligible calendar ageing. 247 Energy storage is designed for a 15-year operational life with no scheduled cell replacement.
Less than 10% capacity loss over the system lifetime. The energy you contract for is the energy you get — every day for the life of the system.
Supercapacitor systems have inherently low standby losses. 247 Energy storage draws minimal power when not actively cycling — critical for facilities where parasitic consumption directly impacts operating costs.
Accept charge at up to 10 times the capacity per hour. Captures regenerative braking energy from cranes and conveyor systems that lithium batteries cannot absorb fast enough.
Containerised outdoor configurations and indoor rack formats available. Deployable adjacent to high-voltage switchgear, in temperature-controlled plant rooms, or in open-air industrial environments.
The 247 ERP platform monitors, dispatches and optimises energy flows across all connected assets in real time — peak shaving, demand response, grid balancing and predictive load management from one interface.
Network-segmented architecture separates operational technology from IT systems. Encrypted remote communication, role-based access control, and IEC 62443 documentation available for NIS2-regulated facilities.
Proven results. Real deployments.

Common Questions.
- What is the cycle life of 247 Energy supercapacitor modules?
- The projected cycle life exceeds 15.000 cycles at 25°C, with a certified product lifetime of 10 years, significantly longer than conventional lithium-ion or LFP batteries.
- Are 247 Energy supercapacitors safe for indoor installation?
- Yes. The solid-state, non-chemical cell chemistry produces zero risk of thermal runaway. Products can be installed in existing buildings without modification to fire suppression or structural requirements.
- What temperature range do 247 supercapacitor modules operate in?
- The modules operate from -20°C to +50°C without active cooling systems, making them suitable for outdoor installations and thermally challenging industrial environments.
- Do 247 supercapacitor batteries contain cobalt or lithium?
- No. The graphene nanotube composite cell chemistry contains no rare or expensive metals, including no cobalt and no lithium, eliminating supply chain ESG risks associated with conventional battery chemistries.
- Can a supercapacitor replace a lithium-ion battery in a commercial building?
- Yes. The 247 Energy supercapacitor delivers battery-like energy storage with zero thermal runaway risk, a 15.000-cycle projected life, and no active cooling required. It is a direct alternative for peak shaving, demand management, and solar integration in commercial buildings, and can be installed without fire suppression or structural modifications.
- How does supercapacitor storage reduce my electricity bill?
- The 247 supercapacitor system stores energy during off-peak tariff periods and discharges during peak demand windows, directly reducing the demand charge component of the electricity bill. For most commercial and industrial operators, the peak demand charge is the largest variable cost on the electricity account, and eliminating it is the primary driver of payback.
- What inverter brands are compatible with 247 supercapacitor storage?
- 247 Energy storage systems are compatible with all standard grid-tied and off-grid inverters. The RES 10 kWh communicates via CAN, RS485, and Bluetooth. Containerised units in the SuperCap 250-1000 kWh range include the inverter as standard.
- How does 247 Energy supercapacitor technology compare to Tesla Powerwall or CATL systems?
- Unlike lithium-ion products from Tesla or CATL, 247 supercapacitor modules carry zero thermal runaway risk, contain no cobalt or lithium, and achieve up to 15.000 cycles versus the 3.000-5.000 cycles typical of lithium-ion alternatives. No active cooling is required, and the total cost of ownership over the product lifetime is lower due to the extended cycle life and absence of replacement costs.
- Is the system insurable and bankable for asset finance?
- Yes. The solid-state, non-chemical cell architecture, combined with IEC 62619, CE, and RoHS certification, positions 247 storage systems favourably with insurers and asset financiers. The absence of thermal runaway risk removes the fire risk premium that lithium-ion installations typically carry.
- What is the self-discharge rate of 247 supercapacitor modules?
- The cell self-discharge rate is 2% per month for the RES 10 kWh and 3% per month for the containerised SuperCap range. This is significantly lower than conventional supercapacitors and comparable to quality stationary storage cells, making the products well-suited for applications with irregular charge cycles or seasonal demand profiles.
