01
Measure correctly
Generation, grid import/export, battery state and flexible loads must be measured at the correct point and updated quickly enough.
- Grid-flow direction
- PV power and state of charge
- Temperature and enable signals

Energy management
We connect solar, storage, EV charging and heat through reliable measurement, understandable priorities and defined safe states.
Direct answer
Energy management decides where each kWh goes: direct use, battery, car, heat or grid. Sound measurements and fallback rules matter more than flashy automation.
02
Set priorities
Together we decide which load comes first and which reserves remain. Rules can change with season, tariff or vehicle availability.
- Direct use first
- Minimum battery reserve
- EV and heat as flexible loads
03
Use robust interfaces
Modbus, digital contacts, APIs and proprietary systems all have limits. We verify compatibility and behaviour when communication fails.
- Documented compatibility
- Safe local control
- Planned expandability
04
Optimise with real data
After commissioning, thresholds and delays are compared with actual operation. Small changes can improve self-consumption and comfort.
- Review deviations
- Tune thresholds
- Useful, actionable alarms
Project process
From first idea to stable operation.
- 01Map sources and loads
- 02Define priorities and limits
- 03Integrate meters and controls
- 04Test faults and optimise
FAQ
Frequently asked questions
Must everything be one brand?+
Not necessarily, but interfaces must be documented and stable. We verify the exact product combination before promising functions.
Can Home Assistant be integrated?+
Yes, where suitable interfaces exist. Safety functions remain independent of the higher-level smart-home logic.
What happens without internet?+
Essential functions should move to a defined local state. Any cloud-dependent convenience features are clarified during design.
