1: Solar PV collector (module) array
Sun rays excite electrons inside the solar
panels which create DC electric current.
2: DC isolation switch
Isolates the generating system from the
electrical grid when needed.
3: DC / AC inverter
Converts the DC power into standard
household AC power for use in the home,
synchronizing with utility power whenever
the electrical grid is distributing electricity.
4: AC isolation switch
Isolates the generating system from the
electrical grid when needed.
5: Credit meter / net meter
The produced PV electricity that is not
used in the household goes back to the
national grid and by this the net meter can
keep track of what the owner of the PV
system have in credit at the national
electrical power supply company and will
only be charged for the consumed
electricity.
6: Electrical panel (consumer unit)
Distributes solar electricity and utility power
throughout the household.
7: Household supply
8: Heat pump (connected to household supply)
(by connecting a DC signal from the inverter to the
heat pump, the heat pump will recognize when there
are free solar power available on the grid in the
household. PV function must be activated. Read
more details in our user manual)
9: Electricity meter
Measures the amount of electricity consumed by the
household.
10: Utility power
is automatically provided at night
and also during day time when the demand exceeds
the solar power production.
The 3D model is only a principle model. All external
connections must be carried out according to
national and/or international legislations to keep
manufacturer’s warranty.
