Application
Store daytime solar generation and use it when site demand is higher than PV output.
Solution
Self-Consumption Optimisation
Store daytime solar generation and use it when site demand is higher than PV output.
Project lens
Sunket Supply scope
Product supply, inverter matching, European warehouse coordination and project-scoped support.
Best fit
Commercial and industrial buyers, installers and distributors planning energy projects in Europe.
The challenge
Use more of what you generate
The economics of commercial solar now favour using your own generation over exporting it.
Feed-in tariffs are low, so exported solar earns far less than the grid price you avoid by self-consuming.
Daytime generation often exceeds daytime demand, creating surplus that is wasted without storage.
Operations want a measurable cut in grid purchases, not just nameplate capacity.
How it works
How self-consumption optimisation works
Shift surplus daytime solar to the hours when your site actually needs it.
- 01
Generate
PV can supply daytime loads directly within the site and grid-connection design.
- 02
Store surplus
Excess generation charges the battery instead of being exported.
- 03
Discharge on demand
Stored energy can cover selected demand periods within the battery, inverter, firmware and phase-loading limits confirmed for the project.
- 04
Monitor
Configured monitoring can report self-consumption, self-sufficiency and grid draw using the data points available for the project.

FAQ
Frequently asked
What self-consumption rate is realistic?
The achievable rate depends on the interval load curve, PV generation profile, storage sizing, operating reserve and export rules. We model it from site data rather than applying a fixed percentage.
Can I see the savings?
Available monitoring can report self-consumption, self-sufficiency and grid draw. Data points, history and report access are confirmed for the selected platform and project.
Does this work for shift operations?
Battery dispatch can be designed around single-, double- or continuous-shift demand patterns where the selected controls and available interfaces support the required schedule.
