The right electrical choice is decided before construction site surprises
This decision influences the inverter, the load distribution, the charging station, the heat pump and sometimes the network connection itself.
The method in 6 steps
01
Check existing power supply
Meter, subscription power, panel and equipment already present provide the starting framework.
02
Look at the target power for photovoltaics
Some powers remain simple in single-phase, others become more coherent in three-phase.
03
List the major current and future uses
11 kW terminal, heat pump or technical workshops clearly change the logic of choice.
04
Integrate the constraints of the local DSO
The network manager can influence metering, injection and commissioning.
05
Compare the cost of adaptation with the real interest
Switching to three-phase has a cost. It must be compared to the concrete gain for the project.
06
Decide according to the evolution of the building
If the building is going to become more electrified, three-phase often becomes more relevant in the medium term.
