Measure energy flow
A meter at the correct point records import and export.
Solar surplus control
Direct solar power to where it creates the greatest benefit.
PHT measures power flow at the grid connection and controls loads according to power, priority, comfort and technical limits.
MeteringPrioritiesLoad managementMonitoring
Quick answer
Surplus control starts with reliable measurement. Only when generation, building load and grid flow are known can batteries, hot water, heat pumps, EV charging or other loads be enabled in steps or proportionally.
Solar surplus control
A robust priority sequence
Define priorities
Rank the building, battery, heat, mobility and flexible loads.
Protect limits
Respect minimum run times, temperatures, state of charge and connection capacity.
Make results visible
Monitoring shows whether the rules work in real operation.
Process
From the first photograph to a working installation.
Record the baseline
Check meters, inverter, loads and communication paths.
Design the strategy
Set priorities, thresholds, power limits and exceptions.
Integrate interfaces
Connect devices through suitable protocols or enable contacts.
Tune with data
Review performance in different seasons and improve it.
Solar surplus control
A robust priority sequence
1. Current building load
PV automatically supplies the demand that exists now.
2. Storage or heat
Energy is stored electrically or thermally according to season and objective.
3. Other flexible loads
EV charging, processes or optional mining operate within clear limits.
4. Export
Surplus that cannot be used sensibly is exported or curtailed where required.

Local SEO should not consist of copied town pages. A real project depends on the grid connection, current tariffs, shading, building services, permissions and measured demand. PHT combines these local facts with an integrated system design.

Frequently asked questions
Frequently asked questions
Does every installation need complex energy management?
No. Once several controllable components interact, coordinated control improves transparency and avoids conflicting rules.
Can it respond to dynamic prices?
Yes, where tariff data, metering and device access are available. The all-in price must be used.
What happens if communication fails?
The installation needs safe default states. Heating, storage and other loads must remain within their own protections.
Can PHT integrate third-party equipment?
It depends on interfaces, documentation and manufacturer permissions. Compatibility is checked before commitment.
