Smarter Energy Management, More Value from Solar

From Solar Surplusto Greater Energy Value

A 10 kWh battery stores surplus solar energy so the home can use it when it is needed most.

With SAJ · Recorded

Previously, Jaume exported around 2,400 kWh of surplus solar energy each year while still importing approximately 2,200 kWh from the grid.

With HS3, his home can store that surplus for periods of lower solar generation or higher demand.

Smarter Energy Decisions, More Value Every Day

In late September, Jaume switched to an indexed electricity tariff and activated AI Saving in elekeeper, opening up new opportunities to optimise his energy costs.

What makes his experience particularly interesting is how he uses AI Saving. Rather than pursuing maximum revenue all the time, Jaume chooses between two operating objectives based on his household's needs and weather conditions:

Maximise Revenue:

Takes advantage of electricity price fluctuations to increase potential energy revenue, particularly when solar production is expected to be low.

Self-use Priority:

Prioritises using stored solar energy to meet household demand.

A choice that fits everyday life

For everyday operation, Jaume keeps Self-use Priority as his preferred setting, switching to Maximise Revenue selectively when weather conditions are less favourable for solar generation.

“I started trying AI Saving after switching tariffs, and honestly, it works really well.”

--Jaume, the homeowner

Self-Consumption First. Extra Revenue, Too

With AI Saving, elekeeper helps Jaume balance self-consumption and revenue optimisation based on his household needs and weather conditions. The October results demonstrate the additional value AI-powered energy management can bring, even when self-consumption remains the priority.

Total Revenue in 7 months: €571

Revenue in October: 

€81.64 (Solar PV and storage alone)

+€14.40 (Additional revenue attributed to AI Saving)

This represents additional value generated through intelligent energy optimisation, without requiring Jaume to prioritise electricity-price arbitrage all the time.

With elekeeper, energy optimisation is not a one-size-fits-all strategy. It adapts to different priorities, helping homeowners balance self-consumption and potential revenue on their own terms.

Better Visibility, Greater Confidence

Detailed energy data helps homeowners understand system performance and make better-informed decisions.

Data That Connects to Daily Life

Jaume reported that elekeeper’s grid import and export readings closely matched his electricity bills. This visibility helps him better understand how his system performs.

A More Complete Experience

He also appreciated the system’s appearance, the integration between the inverter and battery, and the responsive support he received when software update issues arose.

“The consumption and energy export data provided by elekeeper are almost identical to the figures on my electricity bills.”

--Jaume, the homeowner

“The elekeeper app is much more comprehensive than the app I used before, providing far more data and graphs, as well as a much more attractive visual experience.”
