01
Right-size capacity and power
We compare daytime generation, evening demand, seasonal loads and autonomy goals. Energy capacity and charge/discharge power are evaluated separately.
- Usable kWh
- Charge and discharge kW
- Future expansion
Storage · Self-consumption
Battery storage
We size storage around the actual load profile: usable capacity, power, inverter, reserve, location and operating strategy must work together.
Direct answer
A battery does not generate energy; it moves solar surplus into hours when the building needs it. A larger battery is therefore not automatically a better one.
02
Integrate the system
We assess hybrid, AC-coupled and retrofit options. The inverter, meter and communication interfaces must form one coherent system.
- New build or retrofit
- Measurement at the grid point
- Coordination with solar PV
03
Backup and safety
Backup, EPS and whole-home emergency supply are different. We define priority circuits, available power, switching and reserve behaviour.
- Essential circuits
- Configurable reserve
- Location and safety distances
04
Operating strategy
Storage may prioritise self-consumption, reserve, peak shaving or dynamic prices. Essential operation should remain safe without the cloud.
- Clear priorities
- State-of-charge limits
- Monitoring and support

FAQ
Frequently asked questions
How many kWh do I need?+
That depends mainly on daily surplus and demand outside solar hours. PV nameplate power alone is not enough for proper sizing.
Will the house run in a blackout?+
Only if storage, switching and selected circuits are designed for it. A battery alone does not automatically provide backup.
Can storage be retrofitted?+
Often yes. We check the inverter, metering, space, protection, approvals and the economics of the retrofit.
