Commercial battery storage designed around your site.
Reduce peak demand, store surplus solar, shift energy to better tariff periods and build greater resilience — with a BESS designed around your load profile and electrical infrastructure.
- Site-specific design
- DNO / G99 / G100 support
- Solar & EV integration
- O&M aftercare
Tell us about the site.
Even rough figures help. Half-hourly data can come later.
Site-led design
Capacity and power sized from real demand
Grid-aware
Connection, export and DNO constraints considered
Integrated
Solar PV, BESS and EV infrastructure designed together
Long-term support
Monitoring, servicing, upgrades and O&M
Start with the operating problem, not the battery size.
Commercial storage can solve very different problems. The useful capacity, inverter power and control strategy depend on which problem matters most.
Use stored energy when site demand spikes.
Battery power can support the site during higher-demand periods, reducing how much power needs to be drawn from the grid at once.
- Reduce short-duration grid peaks
- Support constrained site capacity
- Coordinate with EV charging and other loads
A 200kWh battery is not automatically a 200kWh solution.
Commercial BESS design needs both energy capacity (kWh) and power (kW) considered against the site’s real load profile. We use the site data to understand the opportunity before fixing the equipment.
Half-hourly consumption
Shows when energy is used and where peaks actually occur.
Maximum demand
Helps establish the power requirement — kW matters as much as kWh.
Existing / planned solar
Shows how much surplus PV may be available to store.
Operating hours
A factory, gym, farm and office all have very different load shapes.
Connection & export limits
DNO constraints can materially change system architecture.
Backup priorities
Critical-load power and required runtime need defining separately.

278kWh of storage alongside 300kW of solar PV.
For Grant UK, Sunergy delivered a 278kWh commercial battery storage system designed to capture and reuse surplus energy from an existing 300kW solar PV array.
The aim was straightforward: increase on-site use of solar generation, reduce avoidable grid import and give the client clearer visibility of how the system performs over time.
- 278kWh commercial battery storage
- Integrated with 300kW solar PV
- Online monitoring and reporting
A commercial BESS project should have a clear engineering route.
We keep commercial storage practical: define what the system needs to achieve, prove the technical route, then specify equipment around that requirement.
Initial data review
We look at bills, half-hourly data, maximum demand, operating hours and existing generation.
Technical feasibility
We review connection capacity, DNO requirements, equipment location, protection and site constraints.
Business case & design
We model the chosen use cases and develop the BESS power, capacity and control strategy.
Delivery & aftercare
Installation, commissioning, monitoring, handover and ongoing O&M support.
Commercial storage, without the jargon.
If you already have half-hourly data or a proposed solar design, send it over — it gives us a much better starting point.
Send us the site data. We’ll help work out what storage can actually do.
A bill is enough to start. Half-hourly data, maximum demand and an existing solar design make the first assessment even better.
